Specific wiring
Second sensor installation (2nd floor probe or exterior probe):
• Connect to 1st wire of external sensor (2nd floor sensor) to terminal 2
• Connect to 2nd wire of external sensor (2nd floor sensor) to terminal 3
Master/Relay installation (connecting 2 stats together):
• Connect from terminal 3 on the “master” to terminal 3 on the “relay” thermostat.
• Connect from terminal 2 on the “master” to terminal 2 on the “relay” thermostat.
NOTE: The “relay “ thermostat will no longer use its own floor sensor for thermal regulation. It will turn
on/off in tandem with the master thermostat.
Powering up
You can now power up the thermostat and begin the programming process. An easy to follow menu will
guide you through the programming. If you want to turn on / off the thermostat and heating system, hold
down the recessed button on the bottom of the stat for 3 seconds.
It is important to test the GFCI for correct installation and function. Testing can only be carried out while
the thermostat is calling for heat (see operating instructions for details).
When you have ensured that both the floor sensor ,heating elements and the GFCI are working correctly
you can complete the installation of floor covering and remove the protective cover on the front of the
thermostat.
