WARNING! Electric shock!

Upon opening the housing, live parts are exposed!

ÎAlways disconnect the device from power supply

before opening the housing!

Note

Strong electromagnetic elds can impair the function of the device.

ÎMake sure the device as well as the system are not exposed to strong

electromagnetic elds.

The device must only be located in dry interior rooms.

The controller must additionally be supplied from a double pole switch with con-

tact gap of at least 3 mm.

Please pay attention to separate routing of sensor cables and mains cables.

ÎUnscrew the crosshead screw from the cover and remove the cover.

ÎMark the upper fastening point on the wall. Drill and fasten the enclosed wall

plug and screw leaving the head protruding.

ÎHang the housing from the upper fastening point and mark the lower fastening

points (centres 180 mm).

ÎDrill and insert the lower wall plug.

ÎFasten the housing to the wall with the lower fastening screw and tighten.

ÎCarry out the electrical wiring in accordance with the terminal allocation (see

page 6).

ÎPut the cover on the housing.

ÎAttach with the fastening screws.

2.2 Electrical connection

WARNING! Electric shock!

Upon opening the housing, live parts are exposed!

ÎAlways disconnect the device from power supply

before opening the housing!

ATTENTION! ESD damage!

Electrostatic discharge can lead to damage to electronic com-

ponents!

ÎTake care to discharge properly before touching

the inside of the device!To do so, touch a grounded

surface such as a radiator or tap!

Note

Connecting the device to the power supply must always be the last step

of the installation!

Note

It must be possible to disconnect the device from the mains at any time.

ÎInstall the mains plug such that it is accessible at any time.

ÎIf this is not possible, install a switch that can be accessed.

Do not use the device if it is visibly damaged!

Attach exible cables to the housing with the enclosed strain relief and the cor-

responding screws.

The controller is supplied with power via a mains cable.The power supply of the

device must be 100… 240 V~ (50 … 60 Hz).

The controller is equipped with 1 changeover relay to which a load such as a

pump, a valve, etc. can be connected.
