HEAT-MAT NGT-567-0010 Underfloor Heating Thermostat





The NGT thermostat can switch your underfloor heating system on and off at predetermined times throughout the week. Each day of the week is split up into four separate periods, each of which can have a different target temperature. This allows you to lower the temperature in rooms that are unoccupied at different times reducing your energy usage without reducing your comfort. Your NGT thermostat comes ready and programmed with a default schedule which is suitable for most homes. If you do not change the settings your thermostat will follow the default schedule. Your thermostat also features an adaptive function that learns how long the floor takes to heat up and cool down as the seasons change and takes this into account when turning the heating on and off. This ensures the room is always up to temperature at the desired time. The adaptive functions fuzzy logic takes three days to learn the heat characteristics of the room before it operates efficiently

First-time settings

The first time you switch the thermostat on the time, application, floor type and load must be set. The menu will automatically guide you through the process.

  • Set the hour and press the OK button. Then set the minutes.
    Press OK.
  • Now set the date: year, month and day. Confirm the settings with the OK button.

The next menu allows you to select the application you want the thermostat to run on.If the thermostat is in the room to be heated select Room/limit. If the thermostat is outside of the room to be heated select Floor. Once you have chosen your setting press OK. You now need to select your chosen floor covering so the thermostat can take this into account in it’s settings. Select your chosen floor covering and press OK. You now need to enter the loading of the system, this is the kW output of the heating system powered by the thermostat. Select the appropriate loading and then press OK. The thermostat is now ready for use and your underfloor heating will operate following the pre-programmed 4-event schedule. See Factory Settings for full details of this.


General operation

The on/off button allows you to turn the thermostat on “I” and off “0” by sliding the button up and down. When the thermostat is switched off “0”, the relay disengages and your underfl oor heating system will not heat up whatever the temperature. All settings, including time and date, will be saved into the thermostat’s memory. The thermostat is simple to use and program by using the navigation buttons.
The function of each button is indicated above the button in the display.

In various parts of the menus and submenus, you will find the Back menu item.

Engineer settings

The Engineering settings menu contains the following options:HEATMAT-NGT-567-0010-Underfloor-Heating-Thermostat-FIG.13

  • Application
  • Temperature scale
  • Backlight
  • Floor sensor
  • Factory reset
  • Information

Offset temperature

It the temperature the thermostat displays does not correspond to the actual temperature in the room you can adjust the sensor.
Press OK and then enter the correct temperature for the air or floor. The thermostat will then automatically correct itself in the future.Please note that the thermostat anticipates rises and drops in temperature by a few minutes so that it does not over-run the target temperatures. This can lead to the temperature reading shown on the thermostat being slightly above or below the actual readings but is perfectly normal. Confirm with OK.

Adaptive function
The adaptive function ensures that the required temperature has already been reached when you get up in the morning or come home from work. If this function is operating and you have set your underfloor heating to come on at 6:30 am, the fl oor will already be warm by that time, rather than just starting to heat. The adaptive function takes a few days to learn the heat characteristics of your room before it functions correctly. Press OK and set the function to On. Confirm with OK.HEATMAT-NGT-567-0010-Underfloor-Heating-Thermostat-FIG.15

Set the type of regulation used.
There are two options:

  • Floor reg. : The thermostat controls the floor temperature only. A floor sensor must be connected.
  • Room/limit: The thermostat controls the air temperature in the room whilst ensuring the floor never drops below or rises above the floor temperature limits. For this function, the floor sensor must be installed. A fl oor sensor must be connected.

Press OK and select the required application. Confirm with OK.

Temperature scale
The temperature scale allows you to set maximum and minimum floor temperatures and the thermostat will ensure that the floor never operates outside of these limits. Even if a higher target temperature is set for the room, the thermostat will stop the floor from overheating. This is particularly useful for systems used beneath wooden or laminate floors.
Press OK to highlight the minimum temperature. Use the up or down button to select the minimum permissible temperature. Press OK and then select the maximum permissible temperature. Confirm the settings with OK.HEATMAT-NGT-567-0010-Underfloor-Heating-Thermostat-FIG.16

The backlight menu allows you to choose when the display is lit up. The options are as follows:HEATMAT-NGT-567-0010-Underfloor-Heating-Thermostat-FIG.17

  • Auto: The thermostat backlight comes on if any button is pressed and switches off again if no button is pressed for 30 seconds.
  • On heat: The backlight comes on when buttons are pressed and also whenever the underfloor heating is powered up. Const on – The backlight stays on constantly, although it swaps to a lower power state after 30 seconds. This is useful if you want your thermostat to constantly display the time.

Floor sensor
The NGT thermostat can operate with many different models of floor sensors. This allows you to replace most older underfl oor heating thermostats with the NGT thermostat without having to replace the floor sensor. The value of your original fl oor sensor can be set in this menu, and this value is usually listed in the instructions that were supplied with the previous thermostat.
