Temperature setting

MICROLINE has a temperature setting range of 0-40°C.

To help set the temperature correctly, the thermostat has an LED,

which lights red when heating is activated. Set the thermostat to max.

temperature until the required room or floor temperature is reached.

Then reduce the temperature setting until the LED goes out. If

necessary, fine adjustment can be performed after 1 or 2 days.

Night setback

The night setback/economy temperature function is activated via a

230 V signal from an external timer connected to terminal S.

The function is factory set to 5°C (2-8° OTD2). The LED lights green

when the economy signal is active and red when heating is active.

Frost protection

If the signal is connected via a rectifier diode, the thermostat will

maintain a floor/room temperature of 5°C.

Pollution class: 2

Pollution class 2, representative of air circulation in typical homes.

Overvoltage category: III

Pulse voltage 4 kV to IEC 60664-1.

Sensor installation

Floor sensor:

The floor sensor should be installed in standard conduit embedded in

the floor. The conduit should be sealed and positioned as close to the

floor surface as possible.

Room sensor:

The room sensor should be installed in a standard wall box or

mounted direct on the wall. Sensor cables can be extended up to a

maximum of 50 m in length using power cable. Two wires in a multi-

wire cable must, however, not be used if the cable is also used to

supply power to heating cables. The best result is achieved if a

separate cable, installed in a separate conduit, is used for the sensor.

Installation of thermostat with built-in or external room sensor

The thermostat or external room sensor should be mounted on a wall

in such a way as to allow free air circulation around it. It must also be

positioned so as to prevent it from being affected by direct heat

sources (e.g. the sun), draughts from doors and windows, or outside

temperature (i.e. do not mount on outer walls). MICROLINE has a

built in fault circuit which switches the heating off if the sensor is

disconnected or short-circuited.

Thermostat installation

- Open cover.

- Unscrew cover and remove.

- Connect wires from rear as shown in wiring diagram.

- Mount thermostat in wall box - fit frame and cover.
