2. Wire the thermostat as shown in figure 2:
L/N (Line): Connect incoming power supply to the terminal block.
L1/N1 (Load): Connect the heating load wires to the terminal block.
(Above wiring screws should be torqued between 0.7-1.0 N.m)
Ensure the junction box is grounded, and attach the heating cable ground to this location.
S1/COM/ : Connect the floor sensor.
If a spare (redundant) probe has been installed in the floor, tape this to the other probe wire in the junction
box, but ONLY CONNECT (1) SENSOR to the thermostat at any one time.
3. Install the power base into the junction box and secure it using the supplied set screws as
shown in Figure 3.
(Screws should be torqued to approx 0.1-0.2 N.m)
4. Install the thermostat faceplate on the power base; start by aligning the top of the units, then
swing the faceplate down so it comes to rest on top of the power base, with the screw holes lined

Operation：
The thermostat controls your floor heating system based on built-in weekly program, running in
4 or 2 stages per day, 7 days a week.
The default weekly program parameters satisfies most usage scenarios, however you can also
modify the weekly program parameters in the thermostat.
When there is no one in the house, it is recommended to reduce the temperature set-point to
save energy.
The thermostat also has built-in adaptive function. When this function is active, the thermostat
heats or stops heating in advance of next stage to bring the room temperature to the set temp-
erature of the next stage. Please note that after turning the Adaptive function ON, the thermostat
will require a few days of normal operation to learn the time required to achieve the heating
targets selected.
