Installation|

1. Loosen the bottom screw with a Phillips screwdriver, then open
   the thermostat from the below as shown in figure 1. Note: The
   bottom screw does not need to be removed to detach the
   faceplate.

2. Install the thermostat faceplate on the power base; start by
   aligning the top of the units, then swinging the faceplate down so it
   comes to rest on top of the power base, with the screw holes lined
   up; tighten the screw to secure the faceplate to the
   power-base.

3. Turn ON the thermostat and wait for the operating screen to be
   displayed.

Heating Schedule:

Assign seven days a week to the following two schedules:
1. 5+1+1: The Event parameter is the same from Monday to Friday,
with separate Event parameters on Saturday and Sunday.
2. 7: With separate Event parameters every day.
Note: Set schedules, the week can be multiple selections, complete
batch change.

Energy Use:

This option is used to calculate data on energy usage. The user
sets the power in the Power Set. The thermostat will automatically
count the heating time and calculate the energy consumption.

Troubleshooting| Problem

Solution

1. Check if you have 120V/208V or 240V supplied to the Junction
   box.

2. Ensure the power supply is connected to the Line side of the
   thermostat (L/N).

3. Contact your installer for troubleshooting support.

Problem

Warnings:

• Installation or replacement of this product should only be done by qualified personnel.
• To avoid the risk of electric shock, turn OFF the power source from the main service panel before installation of the thermostat.
• Keep thermostat air vents clean and free from obstructions.
• The electric floor heating cable/mat must be by the thermostat supply voltage.

Installation

1. Loosen the bottom screw with a Phillips screwdriver, then open the thermostat from the below as shown in Figure 1：
   Note : The bottom screw does not need to be removed to detach the faceplate.

2. Wire the thermostat as shown in figure 2:
   L/N (Line): Connect the 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 up; tighten the screw to secure the faceplate to the power-base.

5. Turn ON the thermostat and wait for the operating screen to be displayed.

Operation

• The thermostat controls your floor heating system based on a built-in weekly program, running in 4 or 2 stages per day, 7 days a week.
• The default weekly program parameters satisfy 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 a built-in adaptive function. When this function is active, the thermostat heats or stops heating in advance of the next stage to bring the room temperature to the set temperature 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.
