vided. Remove the protective carton from the contacts to
ensure perfect contact.
The marks of the connections are pressed into the plas-
tic above the connection points: N, L, 1, 2 and 3.
230 V mains voltage should be supplied to the receiver
unit. This provides the power supply for the device, but
this voltage does not appear on the terminals 1and 2.
We propose to connect the neutral wire of the network to
point N, while the phase conductor to point L. We recom-
mend using a fork type connection including a switch for
mains connection. Please de-energize the device when
heating is continuously not needed (e.g. summer).
The receiver unit controls the boiler or air conditioner
through a potential-free alternating relay whose con-
nection points are: 1 (NO), 2 (COM) and 3 (NC). Con-
nect the two connection points of the heating or cooling
equipment to be controlled to terminals No. 1 (NO) and
No. 2 (COM), i.e. to the normally open terminals of the
relay as shown in the gure.
