Installation

1. Loosen the bottom screw by a Phillips
screwdriver, then open the thermostat from the upper right side as shown.
Note: You do not need to unscrew the screw completely.

2. Wire as shown:
L/N lead: Connect the power cord using the terminal block.
L1/N1 lead: Use a terminal block to connect the load line.
IN/SNR terminal: Connect the floor sensor.
OUT terminal: Connect to IN/SNR of Power Module.
Note: Disconnect the main power supply before wiring.
If an electric floor heating cable or mat system requires more than 15 Amps, install a power module. [Wiring diameter: 12 to 22 AWG]

3. Install the back cover into the terminal box and secure it with the set screw.
4. Fit the left side of the front and rear covers as shown. Rotate to the right again and press the upper half of the right border until you hear a click. Secure the bottom screw.
Turn on the power and test the GFCI function.

WARNINGS

To avoid risk of electric shock, disconnect all power coming to heater at main service panel before installing the thermostat. Keep thermostat air vents clean and free from obstructions. All wiring must conform to local and national electrical codes and ordinances. Installation must be carried out by qualified personnel.

Ground Fault Circuit Interrupter (GFCI)

This thermostat has a built-in GFCI function that protects people from electric shock. It is very important to check whether the GFCI function is normal or not every month using these check steps:

1. Confirm that the thermostat is turned on.

2. Press the [Test Monthly] button. If a red light appears in the upper left corner of the thermostat and GROUND FAULT appears on the screen, the GFCI function is normal. If there is no response, it means the function is invalid; please contact the dealer or electrical installer.
   Note: Do not press and hold the [Test Monthly] button.

3. Press the [Reset] button. The red light is off and the screen shows the power off state.

4. Press the [Reset] button again. The thermostat is turned on.

If in daily use, the red light is on and the screen appears GROUND FAULT, then you need to check if the ground fault is present by pressing the [Reset] button. If the red light is off and the screen shows the shutdown status, it is nuisance tripping. If not, it means that ground fault has occurred. Please contact your dealer or professional technician immediately.

Instruction

The RFT-P 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 set the temperature down to save energy. The thermostat also has built-in adaptive function. When this function acts, the thermostat heats or stops heating in advance of next stage to bring the room temperature to the set temperature of the next stage. Please note that after turning adaptive on, the thermostat takes a few days to learn the time required.
