NOTE: Thermostat must be ON and screen LIT UP to operate this thermostat unless stated otherwise.
Turn ON/OFF: Quick tap POWER button to turn on and turn off.
To change the time and day tap the OK button. Minutes will flash, use the UP / DOWN buttons to set the minutes. Once correct tap OK again and the hours will flash. Again make changes using UP / DOWN buttons and then tap OK again. Now day will flash, (note the 7 days of the week are represented as numbers 1-7 with 1 being Monday) again make changes using UP and DOWN buttons and then tap OK to finish.
Manual mode activated. Thermostat will hold the current set temperature unit a change is made. To select Manual mode simple tap the SET button to swap between Manual and Auto modes.

Automated / Programmed heating cycle activated. Stat will continuously run the pre-set automated 7 day heating cycle. To select this simply tap the SET button to swap between Auto and Manual modes. See `Automated Program Settings’ for how to set up and program the automated heating cycle.

Automated program – Temporary override. If you wish to manually change the temperature when running the stat in Auto mode simply use the UP/DOWN buttons to change the temperature. The new temperature will now be set and held until the next automated program cycle zone kicks in. During this temporary override time you will see in the bottom left of the screen. Once this time zone ends and the programed cycle moved into the next time zone the thermostat will revert back to the preprogrammed temperature and time cycle. This symbol will then be replaced with
Holiday mode is used to set a single temperature for a set number for days such as when away on holiday. To set up press and hold OK for 5 seconds to enter holiday mode setting. OFF or ON will now be flashing. Use UP / DOWN buttons to select ON and then tap OK. Number of days will then be flashing. Use UP/DOWN buttons to select desired number of days and tap OK again. Temperature will be flashing. Select the desired temperature using UP/DOWN buttons and tap OK to complete set up. Screen will now revert back to home screen and suitcase will now be showing. To check how many days and or time is left before holiday mode ends tap the UP / DOWN button once. NOTE: if you tap the SET button during the holiday mode period, holiday mode will be cancelled and the thermostat will revert back to manual mode.

Child lock to stop unwanted tampering or temperature changes. To activate or turn off simply hold the DOWN button for 5 seconds until the padlock appears / disappears.
When the flame is showing, power is going to heating. The flame will show until the set temperature is achieved. If the set temperature is below the actual temperature the flame will not show as there is no need for the heating to be on.

External NTC sensor / Floor sensor, (not air sensor) is being used to measure main temperature on screen. NOTE: Air or floor or both sensors can be selected (see advanced options B for setting options). WHEN USING UNDERFLOOR HEATING IT IS IMPORTANT TO USE FLOOR SENSOR ONLY.
Read this section on automated program settings fully before trying to program the thermostat. NOTE: The thermostat does not turn on or off it simply changes the set / desired temperature 6 times per day on a 7 day cycle. NOTE: When programming the thermostat you must work in a linear time line from zone 1 – 6 and not jump back and forward in time. NOTE: If you do not want the heating to come on in any part of the day / zone simply set a low temperature for that zone and the thermostat will not turn the heating on unless the temperature drops below the set temperature. NOTE: For ease of programming you can select a 5+2 (factory default),6+1 or 7 day cycle setting. For more information on this or how to change see advanced options A6. NOTE: When programing the thermostat if the screen is left untouched for 10 seconds the thermostat will save changes made and revert back to the home screen. This time can be increased in advanced options A – A5 up to 30 seconds before the thermostat saves and reverts back to home screen if more time is needed.
START: To program each zone hold down SET for 5 seconds and the time will flash and zone 1 will appear in top right corner. The times and temperatures you put into the next 6 zones will be copied across to all days showing across the top right of the screen. Follow the next 3 steps below to work through and set all 6 zones for these days without delay, (it can be helpful to have your time and temperatures for all zones written down first). NOTE: If you have selected 0 (=5+2) in advanced setting A – A6 you will have days 12345 showing across top right of screen at this stage, if you selected option 1 (=6+1) you will have days 123456 showing or if you selected optio 2 (=7) you will have days 1234567 showing. The times and temperatures you put into the next 6 zones will be copied across to all days showing on your screen. In step 5 below you will compete the missing days 6,7 or 7 if you selected options 0 or 1 in advanced options A – A6 1: Change the hours using UP/DOWN buttons for when you want to wake up (zone 1 time) and tap SET to move to minutes. 2: Minutes will flash next, change these again for when you want to wake (zone 1 time) and once correct tap SET to move to temprature. 3: Set temperature will now flash. Change the temperature to the desired temperature and tap SET again to move / set up next zone.. 4: You will now see Zone 2 appear in the top right and the hours will be flashing again. Repeat steps 1 ­ 3 above for all 6 zones. # If you selected option 0 (=5+2) or 1 (=6+1) in advanced option A – A6 go to instruction step 5 below. # If you selected option 2 (=7) in advanced options A – A6 you are finished. 5: Once you complete zone 6 and tap SET you will now see zone 1 reappear top right but the days will change to weekend days. Days 6+7 or only 7 will now be showing. You now need to repeat steps 1-3 above for all 6 zones. These are your weekend zone settings. These days are typically programmed differently to the weekday

zone settings.

6: Once you have completed time and temperature for all 6 zones for the weekend days simply tap SET and you have finished.

To use the automated mode simply make sure the AUTO symbol is showing and the time and day is correct. The below diagram / table gives a general idea on how we

would suggest programming your thermostats 6 zone times and tempratures daily cycle.
