Thermostat

Description

Using the thermostat function, you can select heating or cooling options for several different zones or rooms. The thermostat operates in conjunction with a heating or cooling module. See Heating or cooling module . Up to 20 thermostats may be added in one Niko Home Control installation.

Overview

Operation

Each thermostat can be programmed independently. There are three weekly programmes to choose from: two for the heating function and one for the cooling function. In addition, there are five statuses (DAY, NIGHT, ECO, COOL, and OFF). You can use the pre-programmed settings or enter your personal settings.

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".

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 exterior 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 needed, fill in any gaps in the flush-mounting box or bus cable duct using PU foam.

See Installation in Push buttons with display.
