FLOORTOUCHtm Touchscreen Thermostat User Manual IMPORTANT: Ensure the mains supply is isolated prior to installation. All heating mats and cables must be earthed. Electrical work which is subject to Part P Building Regulations must be carried out by a qualified electrical engineer. All work must conform to BS7671 and the latest 17th Edition wiring regulations. GENERAL Technical Parameters • Weekly programming adopting the latest single-chip computer control technology. Power supply: 230VAC 50/60 Hz • The clock continues after a power failure and the scheduled time settings will not be affected. • Designed for electric underfloor heating. According to the pre-set temperature and time, the thermostat will automatically start and stop the floor heating. • Multiple schedule settings available: 5+2 / 6+1 / 7 days. FLOORTOUCH supports different temperature settings accordingly with 6 time modes daily. Maximum switch power: 16A / 3,600 watts Internal Sensor: Setting Range 5°C ~ 35°C External Sensor: Setting Range 5°C ~ 95°C Sensor: NTC3380, 10Kohms @ 25°C Temperature setting steps: 0.5°C Display type: LCD Display area: 60 x 45m • Users are free to choose manual and full automatic mode for operation. • Keypad lock function. • Flame retardant, safe and easy cleaning. Wiring details: These are printed on the back of the thermostat casing. The floor sensor is connected to terminals T1 & T2 (please note there is no polarity and the twin core sensor cable can be connected either way). The 230V electrical supply connects to terminals L (Live) & N (Neutral). The heating mat(s) connect to terminals L1 (Live) & N1 ( Neutral). Earth connections are made with the back box. When the thermostat is powered for the first time you may see “OFF” on the screen in the lower sub-display. Press ON / OFF symbol to activate and turn on your thermostat. Keypad Lock - Press Clock symbol and Menu at the same time for 2 seconds. Repeat to unlock. LCD display will show the temperature value when keypad is locked. Press the power ON/OFF key to turn the thermostat ON or OFF. The display will be as below when turning OFF. Three types of Temperature Control and Display The thermostat can be set to operate in three different modes; IN: Internal, OUT: External, ALL: combined internal and external. The default setting is IN. Enter the advance functions to change the mode setting. Internal control (IN): Based on built-in sensor temperature measurement & suitable for detection of air or room temperature only. External control (OUT): Based on external temperature Press Menu to choose between Manual Mode and Automatic Mode. measurement & suitable for floor temperature control only. ADVANCED FUNCTION SETTINGS Dual temperature control (ALL): Temperature control based on built-in internal temperature sensor and external temperature sensor (over temperature protection). Suitable for detection of room temperature and floor temperature monitoring. If the external sensor is over temperature, the thermostat will shut down the heater. Press ON/OFF until the sub-display shows OFF, press ON/OFF again, then immediately press Menu. You are now in the Advanced Function Settings. The first display will be Adj. Press Menu to navigate through the menu items. Use UP or DOWN to change the settings. When the setting is IN or ALL the main display shows air or room temperature. When the thermostat is set in OUT mode, the floor icon will be lit and the main screen will display floor temperature. WARNING: The settings are used to set some important parameters of the system and the thermostat has already been debugged and tested by professionals, there is no need to reset. Do not make any improper modifications and permit changes only by a qualified person. To save the data go through the functions then exit at any time by pressing the menu key. In the Automatic mode, the main display area will alternately display the day of the week (WEEK) and the daily schedule stage (STAGE). Manual mode: The schedule programme is overridden and the temperature can be adjusted to your individual requirements. The system will control at this temperature without any change. Automatic mode: System will control temperature according to the preset temperature values in different time settings. The Auto symbol will show, which means the system is running under Automatic mode. Setting the time and day of the week In the sub-display it will show the set temperature and time alternately. Press UP & DOWN arrows to adjust temperature settings and other settings.

Press UP or Down to set the correct minutes. Press Clock again to confirm. Press the Clock symbol for 5 seconds to enter into time adjustment. The number representing the day of the week will flicker. Press UP or DOWN to select the day of the week, 1 = Monday, 2 = Tuesday and so on. Press Clock again and the hours will flicker. Use UP or DOWN to set the correct hour To check the floor temperature when the thermostat is set in ALL mode, press Clock and DOWN at the same time. Then the large main display will show the floor temperature. The label FLOOR icon will appear in the lower sub-display. Schedule Settings go back to previous settings. Finally, press ON/OFF twice to confirm. Press Menu for 5 seconds to enter the schedule settings mode. The display will show the featured week e.g. 5 + 2 / 6 + 1 or 7 days. Each period can be set for the desired time and temperature. Six periods can be set P1, P2, P3, P4, P5 & P6. Use UP or DOWN to adjust the hours then press Menu, the minutes flicker. Press UP or DOWN to adjust the minutes. Press Menu then the large temperature displayed will flicker. Press UP or DOWN to adjust to the desired temperature in period P1. Press Menu to move onto the settings for P2. Repeat this procedure through P1 to P6. You can press the Clock icon to If you want to turn off a period, then in the temperature setting for the period press DOWN until OFF is displayed in the temperature screen then press Menu to confirm. To quickly return to the original display press ON/OFF twice. The system default is 5 + 2 and the default settings are as the following table. For example, when the system time is Friday 08:20 under Automatic mode the display would show as STAGE 2 and the set temperature value would be 15°C. 5+2 mode ID P1 P2 P3 P4 P5 P6 Monday to Start time 06:00 08:00 11:30 12:30 17:00 22:00 Friday Set value 22°C 15°C 15°C 15°C 22°C 15°C Saturday to Start time 06:00 08:00 11:30 12:30 17:00 22:00 Sunday Set value 22°C 15°C 15°C 15°C 22°C 15°C Temperature Override Facility – Manual Mode Only This allows you to override the temperature setting at any time. For example, you arrive home early and want the heat on. Press Menu to enter Manual mode. Assume the set point in the schedule was 15ºC and the room temperature is actually 18ºC. The heating will not be energised in this setting. Press UP or DOWN to adjust the temperature above 18ºC. Let’s say 22ºC, and the heating symbol will appear and the heating is now ON. INSTALLATION A: Hook B: Central fixing lug 1.Remove the bezel to start the installation by pushing the bezel away from the main body of the thermostat 4.Make the wire connections into the back of the thermostat as shown in the H3 wire diagram 2.Pull outwards on the central fixing lug and at the same time lift the whole body assembly so that the hooks on the steel back plate can be released. The steel back plate can then be removed 5.Align the four hooks and with a press down movement click the main body of the thermostat back in position on the steel back plate 6. Replace the bezel and the installation is complete 3.Screw the steel back plate into the back box but not too tight to prevent deformation of the steel plate A A B A A External Sensor PROBLEMS and SOLUTIONS There is no display a) Check power supply to thermostat. b) C heck the thermostat is wired as the wiring diagram on the back side of the thermostat. Display ruptured Displays ER0 or ER1 a) E R0: Built-in sensor is damaged. Avoid damage to the small black dot sensor which can be found behind the temperature sensing window of the main thermostat panel. b) E R1: The system is set in dual Temperature Control mode (ALL) and the external sensor is not connected or is damaged. Missing segments from numbers or letters on LCD a) D isplay has been subjected to abuse with hard objects or sudden force. Check whether the steel plate has been deformed during installation. If deformed, correct it. Display a black screen Large deviation of measured temperature and the actual temperature a) I f the display surface temperature is too high. Please note whether there is a heater nearby and if so, remove. a) T he thermostat should be installed in a ventilated room and never in direct contact with sunlight or localised heaters. b) Check terminal connections, including the sensor.
