Thermostat

This product is no longer available. We recommend using one of the following alternatives to control your installation:

• Niko Home app, in combination with a push button with LED and comfort sensors in each zone
• Digital black

Description

Using the thermostat function, you can select heating or cooling options for several different zones or rooms. The thermostat works with a heating or cooling module or, in the case of electric heating, with the three or six-fold switching module. See Heating- or cooling module.

Up to 20 thermostats may be added in one Niko Home Control installation.

Calibrating the clock thermostat

If the thermostat temperature differs from the actual temperature, the thermostat must be calibrated.

• Only calibrate the thermostat after the installation has been in use for at least two hours as this will ensure that the temperature displayed has stabilised. 
• Do not calibrate the thermostat temperature under extreme temperature conditions.

1. Measure the temperature in the centre of the room using a thermometer.
2. Select CALIBRATION on the following screen:
   

   

3. Press button "C".

4. Use the navigation keys until the temperature on the display corresponds to the temperature measured in the centre of the room. Press button "C".

   

   You can increase or decrease the temperature on the display by six degrees.

   
   

5. Select back using the navigation keys and press button "C".

Installation

A thermostat can be mounted in any room fitted with underfloor heating, a radiator, heating unit or cooling unit. It controls the heating or cooling for the room in which it is mounted.

The thermostat only functions properly when the temperature within the room can be measured accurately. Try to eliminate as many factors as you can that may inhibit the thermostat’s ability to accurately control the room temperature.

Do not mount the thermostat:

• in direct sunlight.
• on an outside wall.
• within the immediate vicinity of a heat generating source (heater, radiator, etc.) or electrical equipment that may radiate heat (TV, computer, etc.).
• behind a curtain.

Do not allow air to circulate behind the thermostat. If necessary, close the holes in the flush-mounting box.

See Installation in Display controls.
