Controller installation

G

De-energise all parts of the system that are to be worked on and 
ensure that they cannot be reconnected without authorisation! 

G

Consider the protection class of the controller before selecting where it
should be mounted (See the technical data)!

G

The (wall-mounted) unit must only be installed on a flat surface. 

G

Before installing it, remove the plate covering the screws shown in Fig.
1 and unscrew the screws. Remove the terminal block cover. The spacing
between the drill holes is indicated on the back of the casing.

G

Screw the device onto the wall and then replace the terminal block
cover. Replace the screw covers.

Installing the room temperature sensor

The room temperature sensor records the temperature at the place of
installation. For this reason, select the place of installation so that the 
temperature measurement process is not hindered.

The unit should be mounted approx. 1.5 – 2 m off the floor. The units
should not be mounted:
- on poorly-insulated exterior walls,
- right next to doors and windows (because of draughts),
- behind curtains or furnishings,
- in direct sunlight,
- in the current of air emitted by the heaters,
- above or near to other external sources of heat, such as radiators, TV

sets, lamps, etc.

Please observe the permissible sensor cable length!
