Installation:
Separate the front housing of thermostat from wall module:
1. Unscrew both closing screws (bottom of stat) until they will not turn any
further.
2. Release front housing by gripping lower half of outer frame and pulling
outwards then upwards
3. Place front housing somewhere safe
4. Run all wires to the wall box. Check to ensure that you have included the
following:
• Power (Live and Neutral)
• Heater (Live and Neutral)
• Floor sensor
• Fil pilote (if necessary)
• External/ 2nd oor Sensor (if necessary)
5. Pull wires through wall box and complete terminal wiring.
IMPORTANT: Ensure that multi stranded wires are fully inserted into the
terminals and secured tightly. Any loose strands should be trimmed as they
could cause a short-circuit.
If connecting more than two heaters, an electrical junction box will be required.
NOTE: Always ensure that the sensor cable is installed in a separate
conduit to the power cables supplying the thermostat and heating system.
Normal electrical installation (see numbering on diagram to right)
2. Connect to Power Supply (Live – 230V AC)
3. Connect to Power Supply (Neutral – 230V AC)
4. Connect to Warmup heater(s) (Neutral – MAX 3600W/ 16 Amps)
5. Connect to Warmup heater(s) (Live – MAX 3600W/ 16 Amps)
7. Connect to 1st wire of oor sensor (colour not important)
8. Connect to 2nd wire of oor sensor (colour not important)

Special installations:
(should only be performed under the supervision of Warmup)
Fil Pilote installation: (only for use in France)
Connect l pilot (F.P.) to terminal 1
Second sensor installation: (2nd oor probe or exterior probe)
You are able to attach a second sensor to terminals 6 and 7. You can then use external sensor function to dene the use of
that sensor:
Master/Relay installation: (connecting 2 stats together)
This feature allows you to use one thermostat to control another. This is useful if you need to control multiple underoor
heating elements with one program.
Use low voltage electric cable to connect terminal 6 on the “master” to terminal 6 on the “relay”
Use low voltage electric cable to connect terminal 7 on the “master” to terminal 7 on the “relay”
On the “master” thermostat these connector cables are in addition to the oor sensor but on the “relay” thermostat the oor
sensor is not necessary. The “relay” thermostat will no longer use its sensors for thermal regulation. It will now turn on/o in
tandem with the “master” thermostat.
- Installed in oor: This is to be used if the oor surface area is very large and delicate to overheating. The reading
from this secondary oor sensor will be used to monitor the overheat limit.
- Installed outside house: 2nd oor sesnor will engage weather compensation. Weather compensation saves energy
by delaying the start of heating period by 10 minutes if the dierence between internal and external temperature
is less than 5°C.
