The heaters and floor sensors

must be tested before they are

laid, once they have been laid

but before the tiles or levelling

compound has been laid and

again before they are connected

to the thermostat. The resistance

(ohms) of each heater should be

measured. You should carry out

the following tests and should expect the results detailed below:

• Heating Cable Resistance Test

Set a multimeter or ohmmeter to record resistance in the range of

0-500. Measure the resistance across the RED-240V or YELLOW-

120V wire and the black wire. Ensure the measured resistance

is within the Reference Resistance Band shown in the Technical

Specifications page for the cable size being tested.

Record the readings in the control card in line with the installation

procedure.

• Earth Fault Check

Set a multimeter or ohmmeter to record resistance in the range

of 200M or greater if available. Measure the resistance across

the RED-240V or YELLOW-120V wire and black wire to the ground

(braid) wire.

Ensure the measured resistance is showing as greater than 200M

or infinite if the meter cannot read this high.

Insulation resistance test

Set an insulation resistance tester to 500VDC. Measure the

resistance across the RED-240V or YELLOW-120V wire and black

wire to the ground (braid) wire.

Ensure the measured resistance is showing greater than 200M to

indicate a pass.

NOTE: Due to the high resistance of the heating element, it may

not be possible to get a continuity reading from the heating cable

and as such, continuity testers are not recommended. When

checking resistance, make sure your hands do not touch the

meter’s probes as the measurement will include your internal body

resistance and render the measurement inaccurate. If you do not

get the expected results or at any time you believe there may be a

problem, please contact Warmup’s Technical Team for guidance.

How to test the heater & oor sensor

Floor Sensor

Ensure that the floor sensor is tested before the final floor

finish has been laid. The floor sensor values can be found in the

thermostat instructions. When testing the floor sensor ensure that

the meter can read up to 20k. Warmup thermostats use a 10k

floor sensor @ 77°F (25°C). For temperatures between 68°F (20°C)

and 86°F (30°C) the resistance of the floor sensor should measure

between 8k and 12k.
