TH111RCD-P (230-240 VAC) OWNERS GUIDE Installation This thermostat is designed to control electric floor heating systems. The resistive load must not exceed 4000 watts (NI) @ 230-240 VAC (16.7 A). The thermostat is equipped with a residual current device (RCD) and therefore the isolation of the line and load are required for operation. During an earth fault, the two lines of the load will be cut off from the 230-240 V line. Connect the thermostat as shown in the diagram. Electricians or experienced technicians should install the thermostat. This thermostat is designed to be used with a circuit breaker. PARTS INCLUDED - One (1) TH111 RCD-P (230-240 VAC) thermostat - Two (2) 6-32 screws - Four (4) solderless connectors (for copper wire) - One (1) temperature sensor with a 4.5 metre 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 230-240 V LINE 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. WARNING : Special CO/ALR solderless connectors must be used when connecting with aluminiumn 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 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 performance. The sensing probe should be centered between the heating wires. 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 • When the power is applied for the first time, the display will show the following - Time.00:00 - The floor temperature - Manual mode icon • If there is other information that shows up on the display then the power may have previously been on or the installation may be defective. Contact your local distributor. • The warning light (GFI) must be off. • The message LO or HI will appear on the display if the temperature sensor is defective or the temperature is below 0°C or higher than 60°C. • The heating indicator will be present on display and the relay will be closed due to the current going in the load. Checking residual current device (RCD) • Adjust the setpoint temperature until the heating indicator appears on the display. • Press on the 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 the above events do not occur then check the installation • Press the RESET button to reset the RCD If the RCD test fails • Check the load wires • The thermostat must be in heating mode to carry out the test (heating indicator ON) The RCD test should be carried out monthly. If the test fails : • Cut off the electric power to the heating system • Call customer service or return the thermostat to your supplier for verification • If the warning light comes on during the normal operation, cut off power to the heating system and have an electrician verify the installation Options Selection At the back of the thermostat, there are 3 pre-set factory options as follows : • Temperature in degrees centigrade (default) or Fahrenheit • Time in 12 or 24 hours (default) You can press on Day, Hour and Minute buttons to adjust the time and day • Normal operation (default) or Early Start function This is a built in function, which, when used in conjunction with the timer functions, enables the thermostat to calculate the optimum time to start the heating system to achieve the desired temperature setting at the programmed time. This function has the ability to start the heating system as early as 6 hours prior to the programmed time. In order to enable this function, set the switch E.S. to “ON” at the back of the thermostat. You will have to ensure that the main power is turned off before you enable this function. Comfort, Economy and Vacation settings These settings represent the temperatures you wish to have During the day or when the heating is required Comfort At night or when the heating is not required Economy While you are away for an extended period Vacation How to program your settings Comfort Setpoint Temperature (when the heating is required) The Comfort temperature can be set as follows : First press the button Then select the temperature that you require (by using the arrow keys at the bottom of the thermostat) Finally press and hold the button for approximately 3 secs until the icon Economy Setpoint Temperature appears on the display. (at night or when the heating is not required) The Economy Temperature can set as follows First press the button Then select the temperature that you require (by using the arrow keys at the bottom of the thermostat) Finally press and hold the button for approximately 3 secs until the icon Vacation Temperature (while you are away for an extended period) appears on the display. The Vacation Temperature can be set as follows : First press the and buttons Then select the temperature that you require (by using the arrow keys at the bottom of the thermostat) Finally press and hold the is displayed. and buttons simultaneously for approximately 3 secs until the icon Press the Mode button to exit this function and return to the normal operating mode. Operating Modes The TH111RCD-P has two operating modes – Automatic and Manual In order to select an operating mode, press the MODE button at the right panel of the thermostat. AUTOMATIC This mode uses your own chosen programming. In order to activate this mode, • Press on the Mode button to display the automatic icon. • When the Mode button displays the automatic icon - the use will indicate which temperature setting is being used. or icons whichever are currently in • The icon of the program no. will also be shown. MANUAL This mode allows you to maintain a constant temperature of the floor • Press on the Mode button to display the Manual icon • Set the desired temperature using the arrow keys or • You can select the pre programmed Comfort or Economy or Vacation settings.
