Installation and configuration

5.1.

Wall installation

Four 4.2 mm holes for installation are located on the under-
floor heating controller.
Take the 52 mm installation height of the under-
floor heating controller into account. If the under-
floor heating controller is installed at a severe
angle, the transformer must be on top to allow for
ventilation.

Setting the thermal actuator type

Only one thermal actuator type can be connected
per underfloor heating controller. If normally open
and normally closed actuators are to be oper-
ated, you require two underfloor heating control-
lers.
The thermal actuators are protected by a ceramic
fuse.
► Check the type of thermal actuator being used.
► Set the switches in accordance with the following table
(see the fold-out page, Fig. 4 (10)):
