1. Connecting wires and mounting thermostat PROGRAMMABLE FloorStat Connect the rear thermostat wires to the power supply and to the load using solderless connectors for copper wires. See schematic diagram. PART NO. 500600-120 SUMMARY OPTIONS SELECTION At the back of the thermostat, there are four selection switches to set your preferences. The first is not used. The next three set: Temperature in °C or °F, time in 12 or 24 hours, and early start function. TO SET TIME AND DAY Press on DAY, HOUR and MIN buttons to adjust time and day. 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. 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 . 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. OPERATING MODES To select an operating mode, use MODE button. AUTO: Runs the program. or shows temperature setting and can override temporarily your programming up to the next program. MAN: Maintains the selected temperature. the temperature setting. or 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. 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 need to be respected). The wire must pass outside the electrical box and follow the wall down to the floor. 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 or adjacent to a heating wire. changes Power-up 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. The message L0 or HI will appear on the display if the temperature sensor is defective or the temperature is below 0°C (32°F) or higher than 60°C (140°F). Also, the heating indicator will be present on display and the relay will be closed (current going in the load). INSTALLATION This thermostat is designed to control floor electric heating systems. The resistive load must not exceed 2000 watts (NI) @ 120 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. The polarity of line connection (line and neutral) must be respected. During a ground fault, only the current in the black wire (line) of the load will be cut-off. Connect thermostat as shown on diagram. Electricians or experienced technicians should install the thermostat. This thermostat is designed to be used with a self-protected heating system equipped with thermal cut off and circuit breaker. PARTS INCLUDED • One (1) 500600-120 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. 920-111-016-00-1-A 1/2 06/01/2003 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 (d) Example 2: The 500600-120 have two (2) operating modes. Comfort period: Monday to Friday from 6:15 AM to 8:15 AM and from 5:00 PM to 10:00 PM.

NOTE: It is faster to program the same schedule for every day and then modify the exception days. This mode executes your own programming. 1. Press on PGM button to access the programming mode. 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. 2. Press on Day button 3 seconds to select every day of the week. Memory back-up In the event of a power failure, an internal circuit will maintain the programming and the time. But only the time could have to be set if power failure is more than 2 hours. 3. Press on Hour and Min buttons to enter 6:15 AM Prog. 1, ( 4. Press on PGM button to select Prog. 2 ( enter 8:15 AM. ). ) and Hour and Min buttons to 5. Repeat step 4 to enter Prog. 3 (5:00 PM) and Prog. 4 (10:00 PM). NOTE: When making modifications, make sure you are in the right program. Early start function The thermostat is providing a built-in function enabling it to calculate the optimum time to start the heating system to achieve the desired temperature setting at the programmed time. This function could start the heating system as early as 6 hours prior to the programmed time. To enable this function, set the switch E.S. to “ON” at the back of the thermostat. PROGRAMMING Programming the time and day 1. Set the time using the Hour and Min buttons. 2. Set the day using the Day button.
