unit then fix the back panel to the wall in the vicinity of the boiler
with the screws provided. Remove the protective carton from the
contacts to ensure perfect contact. The marks of the connections
are pressed into plastic above the sensors:

and

.
230 V mains voltage should be supplied to the receiver unit. We
recommend using a fixed cable instead of a fork type connection
for mains connection to avoid any unintentional de-energization of
the device. We propose to connect the neutral wire of the network
to point
N
, while the phase conductor to point
L
. We propose to
interpose a switch so that the receiver unit can be de-energized
if required.
The receiver unit controls the boiler through a potential-free
alternating relay whose connection points are:
1
(NO);
2
(COM);
3
(NC). The connection wires of the boiler should be connected to
terminals
1
(NO) and
2
(COM) to control a heating equipment, while
the connection wires of the cooling equipment should be connected
to terminals
2
(COM) and
3
(NC) to control a cooling unit.
ATTENTION!
The instructions of the manufacturer of the heating
(cooling) equipment should always be followed!
