Measure and record on the test sheet the
resistance of each element and carefully insert all
black and white (red if 240V) cables into separate
Wago connectors as shown in the diagram (fig.8). A
suitable cable will be required to connect the
connector blocks to the output (load) side of the
thermostat.
Please note: If the installed load exceeds the
thermostat power rating then a suitable power
module, contactor/relay must be used.
Measure and record the total installed load
resistance and carry out a resistance check to
ensure no damage to the elements has occurred
during installation. A second resistance
measurement should be taken once the flooring
has been laid.
Finally, complete the test report and warranty
certificate ensuring all measurements are correctly
recorded and leave all documentation including
the thermostat instructions next to the main
electrical supply panel. Remember the warranty must be filled in and kept with a proof of purchase to
ensure coverage by our ten year warranty.
Install the thermostat following the manufacturer’s instructions and carry out an operational test, taking
time to check and adjust the floor sensor limiting temperature if required.
TROUBLESHOOTING
Should you experience any problems with your THERMOFILM installation, please carry out the following
tests before calling Thermosoft technical support.

Step
Test
Outcome
Action
1
Check for a 120/240V supply to the
thermostat
120/240V
If no voltage present,
check electric power
supply.
2
Set the thermostat to the highest
position and test for a 120/240V output.
This may take a few minutes
120/240V
Check resistance of the
floor sensor (step 3). If
normal, the thermostat is
faulty. Contact supplier.
3
Turn off power to thermostat and test
floor limit sensor resistance
Approximately 8-12KΩ for
temperatures 68-86°F
If sensor is faulty, contact
supplier for replacement.
