Thermostat introduction

With the Touch display thermostat (referred to in the following thermostat), you can regulate room or floor temperature. The unit is operated using a touch display. The thermostat can be connected to floor heating systems, radiators or ambient heating systems.

Operating modes
The thermostat can be operated in three different modes:

• Ambient air mode:
  • The internal temperature sensor detects the room temperature. The thermostat controls the load, based on the room temperature.
• Floor mode:
  • The floor sensor detects the floor temperature. The thermostat controls the load, based on the floor temperature.
• Dual mode:
  • The internal temperature sensor monitors the room temperature and controls the load, based on the room temperature.
  • At the same time, the floor sensor monitors the floor temperature and limits this to the predefined maximum temperature value (“max Temp”).
  • This mode is particularly recommended for parquet and laminate floors.
  •  In all operating modes, you can connect an external time switch for temperature reduction (TR).

Installing the thermostat

Thermostat installation

• In order for the thermostat to be operated in ambient air or dual mode, the thermostat must be installed in such a way that it is protected as far as possible against external influences and temperature fluctuations.
• This guarantees reliable detection of the room temperature.
• The following should therefore be taken into account when considering the installation site:
• Minimum installation height: 1.5 m above the floor.
• Do not install too close to windows, doors or ventilation openings.
• Do not install above heaters or other heat sources.
• Do not cover or install behind curtains.
• Avoid direct sunlight and light from lamps

Floor sensor installation

•  In order to guarantee reliable operation in floor and dual mode, the floor sensor must be protected against external influences and temperature fluctuations.
• The following should therefore be taken into account when considering the installation site:
•  If possible, maintain a clearance of 1.0 m from walls and doors.
•  Install sensor in the middle of the loops (see picture below).
•  Place the floor sensor in a plastic tube with an inside diameter of 16 mm.

Wiring the thermostat

• External time switch (TR)
•  Heat load/thermoelectric valve drive
•  Floor sensor

Mounting the thermostat and covers

•  Install the thermostat in a flush-mounted box.
•  Place the frame onto the insert.
•  Press in the snap ring until it presses against the frame.
•  Press on the central plate until it snaps into place

Removing the covers

•  Using a suitable screwdriver, press on the marked points to loosen the central plate.
•  Tilt the central plate forward and remove it.
•  Lift out the snap ring using a suitable screwdriver and remove it.
•  Remove the frame

Starting up

Switching on the thermostat for the first time
The thermostat can be switched on and off using the software shutdown and also using the switch

To switch off using the software shutdown,

•  press „+“ and „-“ simultaneously,
•  hold for 3 seconds,
•  keep pressing when „COdE“ is demanded,
•  thermostat shuts down

Language pin code request

• When the device is switched on for the first time, the display requests the language pin code. This ensures that the messages are displayed in the correct language
• Press “+” until the correct language pin code is displayed.
• The language pin codes are

Operating mode display

• The thermostat automatically detects when a floor sensor is connected and goes to the floor mode (“FLoor”).
• If the floor sensor is not connected, it goes to the ambient air mode (“Air”).
• Also other factory settings are displayed now

Operating the thermostat

Setting the temperature

Select the desired room temperature by pressing “+” or “-“.
• The desired room temperature is shown on the display.
• The blue dot A indicates that the heat load is warming up.

Changing the basic settings

• Hold down “+” and “-” together for three seconds to activate the Settings menu.
•  Enter the language pin code and confirm.
•  Select the desired operating mode and confirm
•  Set the maximum temperature and confirm

The factory setting for the maximum temperature is

•  35 °C in Air mode
•  40 °C in Floor mode and
•  27 °C in Dual mode (Floor max.).

What should I do if there is a problem?

The connected load is not heating

•  Observe the message on the display:
• If “Error HEAt” or “Error FLoor” are shown, load is not connected.
• Investigate the cause of this error.
•  Check the power supply.
•  Switch the thermostat off and back on again.
•  Check the “SAFE”-value setting. The value may be too low.
•  Check the load.
•  If using an external time control device, check the control voltage.

Display is blank:

•  Check the power supply.
•  Switch the thermostat off and back on again
