Thermostat Manual

MODEL FTGF2P (240 VAC) SUMMARY u OPTIONS SELECTION At the back of the thermostat, there are two selection switches to set your preference. 1 Temperature in °C or °F. 2 Time in 12 or 24 hours. u TO SET TIME AND DAY Press on DAY, HOUR and MIN buttons to adjust time and day. u TO RECORD THE (COMFORT) SETPOINT TEMPERATURE Select chosen setpoint temperature by using or button. Press on button (2 to 3 seconds) until icon appears on display. u TO RECORD THE (ECONOMIC) SETPOINT TEMPERATURE Select chosen setpoint temperature by using or button. Press on button (2 to 3 seconds) until icon appears on display . u CHECKING GROUND FAULT CIRCUIT INTERRUPTER (GFCI) Adjust the setpoint temperature until heating indicator ( ) appears on display. Press on TEST button. The test is conclusive if the warning light (GFI) on thermostat is ON and power to the load is cut-off ( remain on display though). If these events do not occur, check the installation. Press on RESET button to reset the GFCI. u OPERATING MODES To select an operating mode, use MODE button. AUTO: Runs the program. or shows temperature setting and can temporarily override your programming up to the next program. MAN: Maintains the selected temperature. the temperature setting. or changes INSTALLATION This thermostat is designed to control electric floor-warming systems. The resistive load must not exceed 4000 watts (NI) @ 240 VAC (16.7 A). The thermostat is equipped with a ground fault circuit interrupter (GFCI) and therefore the isolation of the line and load are required for operation. A certified electrician must install the thermostat. PARTS INCLUDED - One (1) FTGF2P (240 VAC) thermostat Two (2) 6-32 screws Four (4) solderless connectors (for copper wire) One (1) Temperature sensor with a 15 foot extension TURN OFF POWER OF THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRICAL SHOCK. Keep air vents of the thermostat clean and free from obstructions. 1) Connecting wires and mounting thermostat Connect the rear thermostat wires to the power supply and to the load using solderless connectors for copper wires. See schematic diagram. Push the excess wire back into the electrical box to prevent interference with the thermostat. Secure the thermostat using two (2) 6-32 screws. Once the thermostat is properly installed, return power to heating system. 240 V Line 240 VAC Note 1: All cables and connections must conform to the local electrical code. WARNING: Special CO/ALR solderless connectors must be used when connecting with aluminum conductors. 2) Connecting temperature sensor wire Connect the temperature sensor wire to the two lower screws of the terminal block at the back of the thermostat (no polarity needs to be respected). The sensing probe should be placed in a representative heat area for maximum system perfomance. The sensing probe should be centered between the wires in the mat. The temperature sensor wire cannot cross any heater wires and the sensing probe must not be directly ON or adjacent to a heating wire. Power-up 240 VAC To power up thermostat: When power is applied for the first time, the display must show the time 00:00, the floor temperature and the manual mode icon ( ). Other information might show up on the display if installation is defective or does not comply with the instructions. The warning light (GFI) must be off. L0 will appear if temperature is below 0 °C (30 °F), temperature probe defective (open) or not connected. Also, the heating indicator will be present on display and the relay will be closed (current going in the load). HI will appear if temperature higher than 60 °C (140 °F) or temperature probe shorted. Checking ground fault circuit interrupter (GFCI) Adjust the setpoint temperature until heating indicator ( ) appears on display. Press on TEST button. The test is conclusive if the warning light (GFI) on the thermostat is ON and power to the load is cut-off. If these events do not occur, check the installation. Press on RESET button to reset the GFCI. If the GFCI test fails: Check the load wires. The thermostat must be in heating mode to carry out the test (heating indicator ON). The GFCI test should be carried out monthly. If the test fails, cut off the electric power to the heating system and call customer service or return the thermostat to your supplier for verification. If the warning light comes on during normal operation, cut off power to the heating system and have an electrician verify the installation. OPERATING MODES The FTGF2P has two (2) operating modes. MANUAL ( ) This mode allows you to maintain a constant temperature on the floor. 1- To activate this mode, press on Mode button to display the 2- Set the desired temperature using the pre-programmed or or settings. (To select the setting, press on and AUTOMATIC ( icon. buttons or select the simultaneously.) ) This mode executes your own programming. To activate this mode, press on Mode button to display the icon. The or icon indicates which temperature setting is used. Also, the icon of the program number will be shown. Memory back-up In the event of a power failure, an internal circuit will maintain the programming and the time. Only the time will have to be set if a power failure is more than 6 hours. PROGRAMMING Programming the time and day 1-Set the time using the Hour and Min buttons. 2-Set the day using the Day button. Programming the Comfort, Economic and Vacation settings The Comfort , Economic and Vacation settings respectively represent the temperatures that you wish to have during the day , at night or while you are away at work , or while you are away for an extended period . To program your settings a) To program the Comfort temperature, select the desired degree using the buttons and press the button until the icon is displayed (approx. 3 seconds). b) To program the Economic temperature, select the desired degree using the buttons and press the button until the icon is displayed (approx. 3 seconds). c) To program the Vacation temperature, select the desired degree using the buttons and press on the and buttons simultaneously until the icon is displayed (app. 3 seconds). d) Press the Mode button to exit this function and return to the normal operating mode. Schedule programming The FTGF2P allows 4 setting changes for each day of the week. There are no presset programs.The programs are tailored to perfectly adapt to your life style. The principle is very simple. For each day, enter the time at which you wake up (P1), the time you leave for work (P2), the time you arrive back home (P3) and the time you go to bed (P4). Mode Program NOTE : Time 1 Wake-up time 2 Leaving time 3 Return time 4 Bed time For temperature increases (Prog. 1 and 3), allow at least 1 hour.
