Suntouch FloorStat 500600-120 - Thermostat Manual

OVERVIEW

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
  T o 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. or changes the temperature setting.

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.

Connecting wires and mounting the unit

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.

Note 1: All cables and connections must conform to the local electrical code.

Special CO/ALR solderless connectors must be used when connecting with aluminum conductors.

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.

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).

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 500600-120 have two (2) operating modes.

MANUAL

This mode allows you to maintain a constant temperature of the floor.

1. To activate this mode, press on Mode button to display the icon.
2. Set the desired temperature using the buttons or select the pre-programmed , or , or settings.
   (To select the setting, press on and simultaneously.)

AUTOMATIC

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. But only the time could have to be set if power failure is more than 2 hours.

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.

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 , while you are away at work , or while you are away for an extended period .

To program your settings:

1. To program the Comfort temperature, select the desired degree using the buttons and press the button until the icon is displayed (approx. 3 seconds).
2. To program the Economic temperature, select the desired degree using the buttons and press the button until the icon is displayed (approx. 3 seconds).
3. To program the Vacation temperature, select the desired degree using the buttons and press the and buttons simultaneously until the icon is displayed (approx. 3 seconds).
4. Press the Mode button to exit this function and return to the normal operating mode.

Schedule programming

The 500600-120 allows 4 setting changes for each day of the week. There are no pre-set 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).

Program	Mode	Time
1		Wake-up time
2		Leaving time
3		Return time
4		Bed time

NOTE: For temperature increases (Prog. 1 and 3), allow at least 15 minutes per °C. If you have lowered the temperature by 3°C during the night and you wake up at 7 a.m., change the setting at 6:15 a.m.

For savings to be obtained, you must lower the temperature for a period of 2 to 3 times the delay required to bring the temperature back to your comfort level.

Example: If your system takes one hour to go from your saving temperature level to your comfort temperature Ievel, it is useless to lower the temperature for a period less than 3 hours.
