DESCRIPTION
The thermoregulators are designed to fit all standard laboratory baths, especially Techne baths. They will
heat, circulate and safely control the temperature of the liquid in the bath within precise limits. In a
suitable bath, the TE-10 or TU-20 will control the temperature of the liquid within the range -40°C to
250°C (see the specifications for details). However, temperatures from -40°C to 5°C above ambient
require an additional cooling system such as a Techne Flow Cooler.
The instrument consists of the following main parts:
• The pump assembly and base moulding in PPS plastic. The pump can circulate liquid externally under
pressure via its support tubes.
• A heater assembly in 316 Stainless Steel.
• A base plate made from stainless steel to which are mounted the motor, over-temperature cut-out,
mains switch, fuse holder and PCB assembly.
• A cover made from Noryl plastic which is fitted over the main controls.
In the TE-10A, bath temperature is monitored and controlled by a thermistor in conjunction with a
proportional controller.
In the TE-10D and the TU-20D, bath temperature is monitored and controlled by a PRT in conjunction
with a 3 term controller.
Protection in all the units is provided by means of an adjustable over-temperature cut-out. The pump
motor and the transformer are also fitted with thermal fuses.
A portable clamp or a bridge piece are available as alternative ways of fixing the thermoregulator to the
bath.
18
Set Up
1 There are two modes of operation for the pump; circulation internal to the bath; circulation external
to the bath. For internal circulation the blanking caps on the top of the outlet and return pipes
should be securely in place. They screw on and, for safety, they may be tight. For external circulation
these need to be removed.
The outlet nozzle is supplied fitted to the bottom of the pump housing in the internal circulation
position. In this position and with the blanking cap on the outlet pipe the pump will circulate
internally.
If maximum external flow is required: Remove the outlet nozzle from the pump base and reposition
it on the bottom of the return pipe. Remove the blanking cap from the return pipe and screw it onto
the hole from which the nozzle was taken. This redirects the full flow externally. Screw the pipe
connectors supplied with the unit to connect the appropriate pipe to the unit.

2 CAUTION: DO NOT SWITCH THE THERMOREGULATOR ON UNLESS EITHER THE
BLANKING PLUGS ARE FITTED TO THE TOP OF THE PIPES or AN EXTERNAL CIRCUIT IS
FULLY CONNECTED. NEVER SET THE UNIT SO THAT THE FLOW IS SPLIT INTERNALLY AND
EXTERNALLY.
3 Ensure that the bath is set up on a flat level surface.
4 Fit the unit securely to the bath using the correct bridge piece for the unit/bath or a portable clamp,
see the list of accessories. THE UNIT MUST ALWAYS BE MOUNTED WITH THE BACK AND
THE SWITCH END OUTSIDE THE AREA OF THE BATH. This will reduce the infiltration of hot
vapours into the cooling system of the thermoregulator. Ensure that at all times the air inlet and
outlet remain clear of obstructions. Free circulation of air inside the unit is essential for proper
cooling of the electronics and pump motor.

5 Begin by securing the bridge piece to the bath. Use the two M4 countersunk stainless screws and
screw into the holes in the corners of the bath.
6 Locate the thermoregulator above the bridge piece. Toggle the heating element carefully through the
clearance hole. Lower the thermoregulator onto the M4 threaded stud (1) and 3mm diameter stud
(2). Use the half-turn plastic fastener (3) to clamp down the thermoregulator.
7 Use the thumb screw (4) to secure the cover plate to the bridge. Bungs (5 and 6) are provided to seal
off the holes in the bridge piece. It is necessary to fit the bungs to reduce heat losses and prevent
steam or other vapours getting to the thermoregulator.

8 If you do not want to use a bridge piece to secure the unit to a bath then you must use a clamp. The
clamp bracket fits between the pump legs in the slot provided. Slide the bracket into the slot and use
the two screws in the clamp kit to secure the clamp to the unit.
9 If the pump has been set correctly for external circulation, suitable hoses should be fitted to the outlet
and return pipes. A suitable hose must be capable of withstanding both the temperature of operation
and the liquid being used. Always securely clip the hoses in place.
Hose material Allowable temperature range Comments
PVC 10°C to 60°C (50°F to 140°F) For water only
Silicone -40°C to 200°C (-40°F to 362°F) NOT for silicone oil
Viton -20°C to 250°C (-4°F to 482°F)
10 A cooling coil will give control for temperatures between 5°C above ambient and 5°C above the
temperature of the water supply. See the list of accessories as the cooling coil is an accessory on the
TE-10A, TE-10D and the TU-20D.
The cooling coil is fitted to the thermoregulator just below the over-temperature cut-out reset
button. You will find a rubber moulding screwed to the base and filling two slots. Remove the screw

and moulding and use the screw to fit the cooling coil in the slots. Keep the moulding in a safe place
in case you need to replace it. Connect a hose from a tap to one end of the coil and from the other
end of the coil to drain. Adjust the water flow to give the required cooling.
11 For lower temperatures, a Dip Cooler such as a Techne RU-200 or RU-500 or a Flow Cooler such as
the FC-200 or FC-500 is required. Alternatively you could use either the RB-5A or the RB-12A Techne
refrigerated baths, which have integrated fridge coils and no additional cooling mechanism is
required.
See the individual instruction manuals for installation information.
12 If a thermometer is to be used, it may be fitted in the end of the top cover of the thermoregulator
between the two lugs, using the O-ring supplied with the unit. If a bridge piece is fitted, it is
necessary to remove the bung (5) to insert the thermometer through the plate into the bath.
13 Fill the bath to between the minimum and maximum levels stated in the specification. If water is
used, demineralised water is preferred to reduce the formation of scale. If scale should form, use
only mild de-scaling agents to remove it. DO NOT attempt to hammer, chip or scrape the deposits
from the surface of the bath.
14 Recommended liquids:
Temperature Liquid
-40°C to 0°C 40% water, 40% ethylene glycol and 20% alcohol
-20°C to 30°C 50% water and 50% ethylene glycol
5°C to 95°C Water, preferably de-ionised with neutral pH
10°C to 150°C Dow Corning Silicone Oil 200 series*
10°C to 250°C Dow Corning Silicone Oil 210H/100cs series*
*Warning: check gel life at top end of range.
Extraction may be necessary at high temperatures; always check the manufacturer’s data and safety
sheets before using any of the liquids.
In all cases the OVER-TEMPERATURE CUT-OUT must be set correctly for the liquid being used and
the temperature at which it is to operate.

15 A bath that is fitted with a lid or insulating ball blanket gives the best operating conditions. A lid or
ball blanket will prevent vapour loss, heat loss and give better temperature control. If an open bath
is used above 80°C (ie where steam or other readily condensing vapours are present) the operation
of the unit, particularly the digital display on the TE-10D and the TU-20D, may be affected.
Below about 80°C a cover becomes less important but will still give better temperature control.
16 The symbols next to the indicator lamps on the front panel of the thermoregulators have the
following meanings:
: the power indicator
: the heater indicator
: the over-temperature indicator
17 Symbols on the switch have the following meanings:
I : mains switch On
O : mains switch Off

OPERATION
• Ensure that either the outlet and return pipes have their caps on or an external system is properly set up.
• Switch the unit on by pressing the power switch. The switch and the POWER indicator on the front
will light up.
Setting the temperature on the TE-10A
• Turn the knob until the line on the knob points to the required temperature.
• The heater (and heater indicator) comes on if the set temperature is higher than the current bath
temperature. When the measured temperature approaches the set temperature, the heater indicator
will begin to flash. As the measured temperature stabilises the indicator will stay on for shorter
periods.
• Due to variations in heat losses, the actual temperature may vary. If you need to control the
temperature to a greater accuracy than the TE-10A’s accuracy, place a thermometer in the lugs as
shown on page 21. For greater accuracy still you can place the thermometer in one of the samples.
In either of these cases, it may be necessary to readjust the set temperature to achieve the precise
temperature required. Allow the temperature to stabilise after each adjustment.

WHEN SWITCHING ON THE TE-10D OR THE TU-20D
When first switched on the display will show the edition of the software currently installed.
For example software issue “5.12” would be shown as follows:
It will display this for 1 second, then the actual temperature of the bath will be indicated.
THE FRONT PANEL CONTROLS
The front panel controls consist of three buttons for controlling the display, a four digit LED display and
three indicators.
The SET temperature button
The SET temperature button displays the set temperature when pressed.
The UP ARROW button
When the SET temperature button is held down and the UP ARROW button is pressed, the set
temperature is increased.
The DOWN ARROW button
When the SET temperature button is held down and the DOWN ARROW button is pressed, the set
temperature is decreased.
Speed of change of set temperature
Each press of the UP ARROW or DOWN ARROW buttons will increase or decrease the set temperature
by 0.1°C. If the buttons are held down the temperature change will accelerate to 5°C per second.
Power indicator
The top indicator shows that there is power to the unit.
Heater indicator
The middle indicator shows when the heater is heating. When the temperature is being set, and the new
set temperature is higher than the temperature already in the unit, the heater indicator will light as the
unit tries to follow the set temperature. If the light is on continuously the heater is getting constant
power. The only exception is described under over-temperature indicator. As the temperature approaches
the set temperature the heater indicator will flash. When the set temperature is reached the indicator
will stay on for shorter periods. If the bath temperature is above the set temperature then the indicator
will be off, as the heater is not getting any power.
30
Over-temperature indicator
If the unit should, for any reason, exceed the temperature set for the over-temperature cut-out, the
over-temperature indicator will light. The heater will have been switched off and the unit will begin to
cool even if the heater light is on (the light staying on or not depends on which circuit has sensed an
over-temperature).
Low liquid level
The float switch will trip if the liquid gets below a safe level; the display will change to "LLL". The heater
will be switched off. Fill the bath to above the minimum level of 100mm and the display will return to
the 'present' temperature; the unit will again work.
Sensor fault indicator
If the unit there should, for any reason, be a sensor fault, the bottom indicator will light. The power to
the heater will have been switched off and the unit will begin to return to ambient even if the heater
light is on (the light staying on or not depends on which circuit has sensed a fault).
31
AFTER USE
When you have finished heating samples, remember that parts of the unit and the samples may be very
hot. Take the precautions listed earlier. We recommend that the samples should be allowed to cool to
50°C before being removed from the bath. They will still have to be handled with care.
Should you want to remove the unit from the bath, it too should be allowed to cool to 50°C before being
removed.
Remember the bridge, the lid (if used), the bath and all other parts close to the bath will be hot while it
is in use.
32
SETTING THE OVER-TEMPERATURE CUT-OUT
An adjustable over-temperature cut-out is fitted. When the cut-out operates, the heater will stop
working and the ‘over-temperature cut-out indicator’ will illuminate. On the TU-20D an audible alarm
will sound. The pump will continue working on all units.
It should be set to approximately 10°C ABOVE THE OPERATING TEMPERATURE. This can be done in one
of two ways; The first is more accurate and the second quicker (and better if you do not want to overheat
the liquid). For both, first turn the reset button fully clockwise then:
1 Heat the bath to the desired cut-out temperature and turn the reset button anticlockwise until the
cut-out just trips.
Either: Switch off at the mains power. Remove the unit from the liquid and press the reset button.
Return the unit to the liquid, switch on the mains power. The heater will again work.
Or: Allow the liquid to cool, may be as much as 40°C, and press the reset button. The heater will
again work.
2 Heat the bath to the required maximum operating temperature and turn the reset button
anticlockwise until the cut-out just trips. Turn the reset button clockwise one small division on the label
and press the reset button. The heater will again work.
An alarm will sound on the TU-20D when the over-temperature cut-out is activated by a temperature
higher than that set for the over-temperature cut-out. Reset the over-temperature cut-out, by pressing
the reset button, to stop the alarm.
33

RS232 SERIAL INTERFACE
The TU-20D may send data logging information to a compatible computer by connecting the unit and
the PC via an RS232 cable, and installing the “Thermsoft” software. Contact your supplier for details.
The RS232 cable must be fitted to both the unit and the PC before either unit is powered up, otherwise,
data integrity cannot be guaranteed. Once the cable is fitted, it does not matter which unit is powered
up first.
The following tables indicate the cable specifications for a 9-way PC serial port:

ADDITIONAL INFORMATION
NOTE THAT THIS EQUIPMENT SHOULD ONLY BE DISMANTLED BY PROPERLY TRAINED PERSONNEL.
REMOVING THE TOP CASE EXPOSES POTENTIALLY LETHAL MAINS VOLTAGE. THERE ARE NO
OPERATOR MAINTAINABLE PARTS WITHIN THE EQUIPMENT.
In the unlikely event that you experience any problems with your Thermoregulator which cannot easily
be remedied, you should contact your supplier and return the unit if necessary. Please include any details
of the fault observed and remember to return the unit in its original packing. Techne accept no
responsibility for damage to units which are not properly packed for shipping: if in doubt, contact your
supplier.
OPERATOR MAINTENANCE
1. Cleaning
Before cleaning your unit ALWAYS disconnect from the power supply and allow to cool below 50°C.
Your Thermoregulator can be cleaned by wiping with a damp soapy cloth. Care should be exercised
to prevent water from running inside the unit. Do not use abrasive cleaners.
2. Over-temperature cut-out
The over-temperature cut-out is a sensitive mechanical device and mechanical shock can cause it to
trip.
• In the event of no heater power, check the mains plug and lead, then reset the cut-out control.
• Repeated operation of the cut-out indicates a serious fault: you may need to return the unit to
your supplier for repair.
3. Fuses
Your unit is protected by two fuses.
TE-10A & TE-10D 230V 2 x F5A; 120/100V 2 x F10A
TU-20D 230V 2 x F10A; 120/100V 2 x T16A
These should only be changed by suitably qualified personnel.
The fuses must only be replaced by a fuse of the same type and value.
If the fuses blow persistently, a serious fault is indicated and you may need to return the unit to your
supplier for repair.
35
CALIBRATION OF THE TE-10D AND TU-20D
Remember that if you change the calibration from that set at the factory you may change the
calibration at all temperatures. You may get different calibration with different baths and/or
liquids.
In order to ensure that the calibration you are setting is correct, you will need to use an independent
calibrated probe or thermometer.
Set the temperature display to the particular temperature at which you require to control. Measure the
actual temperature of the bath liquid using a calibrated probe or thermometer.
If the calibration is not correct then you can follow this procedure.
a Hold down the Up and Down buttons and then press the Set button at the same time for 5 seconds.
b The display will change from the bath temperature to “EEEE”.
c Press the ‘SET’ button and either the ‘UP’ or the ‘DOWN’ button to adjust the display to the same
temperature as the measured value.
d Press ’UP’ and ‘DOWN together to confirm the value. The display will return to the bath temperature
and the unit will control with the new calibration parameters.
36
Replacement parts
Each unit is supplied with an O ring for a thermometer. The following parts may be purchased if
replacements or alternatives are required:
