TRM-FH-Silver
Quick Start Guide
Programmable Radiant Floor Thermostat
Warnings:
-Installation or replacement of this product should only be done by qualified personnel.
-To avoid risk of electric shock, turn OFF the power source from the main service panel prior to
installation of the thermostat.
-Keep thermostat air vents clean and free from obstructions.
-Electric floor heating cable/mat must be in accordance with the thermostat supply voltage.
-All wiring must conform to local as well as national electrical codes and ordinances.
-Power and Load terminals (L/N/L1/N1) are designed to handle a cross-section of wire measuring
12-22AWG.
-Sensor terminals (A/B/C/D) are designed to handle a cross-section of wire measuring 18-22AWG.
Installation:
1.Loosen the bottom screw using 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 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.
IN/SNR Terminal (C/D) (Floor Sensor):Connect the floor
sensor to this location on the thermostat there is no polarity to this connection.
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.
OUT Terminal (A/B) (External relay communication): Connect to IN/SNR on the Relay power
module (sold separately); used to expand a floor heating system beyond the 15 amp thermostat capacity.
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)
Refer to figure 4 for Junction box dimensions
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 power source (feed breaker).
6. Turn ON the thermostat and wait for the operating screen to be
displayed.
7. Test the thermostat GFCI by pressing the top button marked
'Test'; a Ground Fault message will be displayed on the thermostat screen.
8. Reset the thermostat GFCI by pressing the top button marked 'Reset'; the Ground Fault
message will disappear and the thermostat operating screen will be displayed.
If the thermostat does not reset, and continues to display a Ground Fault message,
contact your installer for troubleshooting support.

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 is functioning normally; the following testing process
should be done monthly:
GFCI Testing steps:
1.Confirm that the thermostats is turned ON.
2. Press the [Test] button. If a red light appears in the upper left corner of the thermostat and
GROUND FAULT appears on the screen, the GFCI is functioning normally. If there is no res-
ponse, contact your installer for troubleshooting assistance.
Note: Do not press and hold the test button
3. Press the [Reset] button.The red light will turn OFF and the thermostat will display the
operating screen.
Note: In daily use, if the RED light is ON and the "Ground Fault" message appears on the screen, you need
to check if the ground fault is actually present by pressing the [Reset] button.If the red light is off and the
screen display returns to the operating menu the unit has nuisance tripped, or been manually tested. If the
ground fault message persist when you attempt to heat up the floor, you may have an actual fault. Contact
your installer for troubleshooting support.
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.
