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.

tion
DANGER
Danger to life through electric
shock!
Contacts that are open are live.
► Unplug the power plug before open-
ing the housing.
► Have all the work carried out by
authorised specialist personnel.
► All wiring must be in accordance with
IEE & Building Regulations.
WARNING
Damage to exposed components!
Destruction of the electronic compo-
nents through electrostatic discharges.
► Do not touch the components.
► Touch an earthed piece of metal to
discharge static electricity from your
body.
6.1. Opening the housing
► Open the housing as shown in Fig. 2 on the fold-out page.
6.1.1. Plugging in the expansion module
(optional)
The expansion module HCS 80 expands the number of
possible temperature zones of the underfloor heating con-
troller from 5 through 8.
► Insert the expansion
module with the adapter
connector into the pro-
vided slot.
6.1.2. 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)):
