2.3 ASSIGNING OF TERMINALS
After switching off the power to the boiler, carry out the wiring using the terminal block on the zone control unit ( fi g.5).
fi g. 5
For the low voltage connections (terminals: 17-33) use cables of section 2.5mm2 max., making sure their path is not the same as that of the mains power cables. The max.
length of cables must not exceed 50 m. For the connections to mains voltages (terminals 5-16) and Earth (terminals 1-4), use cables of section 4.0mm2 max.
The permanent power supply of the zone controller must be connected to terminals 5(L) and 6(N); the cable for communication with the boiler board (OpenTherm Remote
Timer Control terminals) must be connected to terminals 32 and 33 (BLR); a possible External Probe (optional) must be connected to terminals 30 and 31 (T4) if the con-
nection is not available on the boiler board. For the rest of the wiring, use the diagrams given in the following sections.
Room adjustment can occur by means of the Remote Timer Control (OpenTherm) and/or Room Chronothermostats (only with voltage-free contact). In any case, make
sure to use at least one Remote Timer Control to facilitate the user and installer settings.
Generator demand
Regardless of the type of layout to be managed, the zone controller can demand heat from the generator in 3 different ways:
Therefore,
fi rst of all it is necessary to select one of these 3:
1 - Communicating: Generator equipped with Opentherm protocol
