INTRODUCTION

Electrical installation must be in accordance with all applicable national electrical codes (NEC, CEC) as well as local electrical and building codes, regulations and inspection procedures. Electrical inspection of the installation may be required before, during, and after installation. Check with your local electrical inspection department before beginning installation. Per U.S. National Electrical Code – Installation in a bathroom requires that the Thermostat/Equipment Ground Fault Protection Device be installed on a circuit protected by a separate Ground Fault Current Interrupter (GFCI).

New Construction Rough-In

• Fasten electrical connection box (as required per local electrical code) at desired position on side of stud.
• Drill one 1-inch hole in base plate for singlecable installation and two 1-inch holes for twocable installation.
• Thread pull-cord through hole(s) in base plate and in corresponding holes in electrical box. Secure the pull cords in the electrical box. Tie floor ends of pull-cord together with Warning Tags and fasten to floor.
• Install the guard plate over the hole for the cold leads and sensor wire before drywalling.
• Install guard plate as shown in Figure 1.
  

Thermostat Installation

• Pull sensor wire into ECB and secure to the floor. See Figure 2. The sensor must not cross or overlap any other cable on the floor AND must be embedded in the cementituous based mortar in the same manner as the heating cables.
  
• The floor temperature sensor wire can be extended to a maximum of 50 ft with UL or CSA recognized wire 22 AWG rated for 300 V.
• Ensure the supply branch circuit has been disconnected/de-energized.
• Prepare the thermostat for installation:
  1. Remove the thermostat, wire connectors and screws from packaging.
  2. Pop out the Screw Cover by gently pushing from behind, with a screwdriver, see Figure 3.
     
  3. Trim excess length of supply branch circuit, cold lead and temperature sensor cables, as necessary, leaving about 6" (15 cm) projecting from the Electrical Connection Box (ECB), see Figure 4.
     
  4. Prepare each heating cable/cold lead for connection/splicing and connection per Figure 5 or Figure 6, as applicable.
     
  5. Prepare the sensor wire per Figure 5 or Figure 6, as applicable. Use screwdriver for connection to the sensor wire connections (black and white wires) to corresponding BLK and WHT terminals.
  6. Neatly fold all wiring into ECB and fasten thermostat with #6-32 screws provided. Do not apply excessive force to the thermostat. Apply firm but continuous force until the screws can be fully seated.
  7. Align the thermostat, then finish tightening the two screws.
  8. Snap the Screw Covers over the screw heads.

Button Explanation

Screw Covers – Decorative covers which conceal the screws securing the thermostat, easily removable.
LCD Display – Large scale readout which indicates the operational status of thermostat
Mode Switch – Allows easy selection of ON and OFF modes.
Up/Down Button – Used during time setting to move values up or down (if held down for 2 seconds, values will change rapidly).
Back Button – Used during time setting to go back to the previous step.
Accept – Used during time setting to accept the setting, and to advance to the next step.
GFCI Test Button – Used to simulate a ground fault, tests the GFCI circuitry and activates GFCI Fault Light.
GFCI Fault Light – Turns on when a ground fault is detected.
GFCI Reset Button – Resets a simulated, or repaired GFCI fault, and deactivates GFCI Fault Light.

LCD Explanation

Hour Digits – Indicates the time of day with AM or PM.
Sensor – Flashes when the Floor Sensor is malfunctioning.
Floor Temp – The floor temperature readings may be represented in either °F or °C. The operating floor temperature range is from 60°F (16°C) to 104°F (40°C). The displayed floor temperature range is from 32°F (0°C) to 120°F (49°C). The thermostat only functions in the operating floor temperature range (from 60°F/16°C to 104°F/40°C).

– Indicates that the floor heating is energized, flashes slowly during 3 minute standby cycle.

NOTE – Not all display elements will appear simultaneously.

Energizing the Thermostat

"DISPLAY FLASHING"

When power is first connected to the thermostat, the LCD Display flashes as shown. After 90 seconds the display will stop flashing and go to the default time setting of 12:00 AM and display the Floor Temp. The display will also stop flashing if a button is pressed, or the mode switch is moved to another position.

Setting the Time and Day

1. Move the mode switch to the OFF position; the actual Floor Temp Level and current time are displayed.
   
2. To enter the time setting, press and hold the BACK and the ACCEPT buttons for 3 seconds, the AM symbol flashes. Press the UP () or DOWN () button to set AM or PM. Press the ACCEPT button once to accept the AM/PM setting.
   
3. After accepting the AM or PM setting; the Hour digits flash. Press the UP () or DOWN () button to set HOUR. Press the ACCEPT button once to accept the HOUR setting.
   
4. After accepting the Hour setting; the Minute digits flash. Press the UP () or DOWN () button to set the Minute. Press the ACCEPT button once to accept the minute value and exit the time setting program.
   During the previous steps, if no key input is received for 90 seconds or the mode switch is moved to other position, the thermostat will exit the time setting mode and reset to the Default value of 12:00 AM.
   The time is now set, the thermostat clock will start running.

Selection of thev Temperature Scale (Fahrenheit or Centigrade)

1. Move the mode switch to the ON position; the Floor Temp and current time are displayed.
2. To enter the temperature scale selection; simultaneously press and hold the BACK and the ACCEPT buttons for 3 seconds. The "F" or "C" digit flashes.
3. Press the UP or DOWN button to toggle between F and C.
4. Press the ACCEPT button once to accept the F or C scale and exit the setting.

Floor Temp setting

Slide the mode switch to ON position, press and hold the UP () or DOWN () button for 1 second (temperature display will flash) and then repressing the UP () or DOWN () button for each degree that you want to increase/ decrease. Display stops flashing when UP () or DOWN () button is not pressed for 5 seconds, and then the new temperature setting goes into effect.

Ground Fault Interrupter (GFCI)

The thermostat has an integral Ground Fault Protection Device (GFCI) circuit to isolate faults on the heating cable load. Test this circuitry monthly. Press the TEST button once to simulate a fault; the red GFCI light will come on and the "GFI" symbol will flash on the display. Press the RESET button to restore power to the cables, and return the floor temperature setting to the original setting.

• If the GFCI trips and can't be reset, turn the Mode switch to the OFF position, and have a qualified electrical technician check on the electrical circuit before energizing the system again.
• Under NO circumstances should the thermostat be bypassed, and the heating cables energized, when a fault condition exists.

Power Outage Recovery

Power interruptions to the thermostat will not affect the time or Floor Temp settings. However, a power interruption of greater than approximately 10 minutes will require that the clock be reset (see "Setting the Time" above). Of course, for extended power interruptions, the display will remain blank.

Sensor Icon

If the thermostat detects a fault with the Floor Sensor, the Sensor icon will flash on the LCD display. The power to the heating cable will be disabled.

Changing the Door

The GT series thermostats come with 2 doors, allowing you to customize the look of your thermostat to best match the room decor. The doors remove easily. With the door halfway open, gently pull down at the bottom hinge point and twist the door away from the thermostat. Simply reverse the process to install the new door.
