HCE80(R) / HCC80(R) Mounting and operation 13
Installing an external antenna
Up to three underfloor heating controllers
can be connected to an antenna.
1
Only install the external antenna outside
metal housings (e.g. control cabinets).
2
Install the antenna at a suitable location near
the underfloor heating controller (3).
3
Strip the connections 5.5 mm (see
fold-out page, Fig. 5).
14
Connect the antenna (see fold-out page, Fig. 4 (9)):
Shield to Terminal 2, second conductor to Terminal 1
5
Close the terminals.
Operation with several underfloor heating controllers
If several underfloor heating controllers are operated
simultaneously, an antenna (internal or external)
may only be connected to one controller.
Closing the housing
1
Place the housing cover back on (see fold-out page).
2
Snap the left and right snap lock back into place.
3
Tighten the screws on the top.
Commissioning
During commissioning, room setpoint
generators/sensors and, if applicable, the
time programs of the central operating
devices are assigned to the temperature
zones of the underfloor heating controller.
1
Connect the underfloor heating
controller to the supply voltage.
The mains voltage LED (POWER) lights up.
LED displays at the underfloor heating controller
The LEDs on the underfloor heating controller
(see fold-out page, Fig. 3 (1, 2, 3)) indicate
the operating modes of the underfloor heating
controller and the installed temperature zones.
