2. INSTALLATION

2.1 ASSEMBLY
Attention!
Always make sure the mains power is disconnected before opening the enclosure.
Installation must only be carried out on a closed and dry place. To ensure proper operation, make sure there are no strong electromagnetic fi elds in the place of installation. The controller must be separated from the mains power
supply by means of an additional device (with a disconnection distance of at least 3 mm on all poles), or by means of a disconnecting device complying with the regulations in force, During installation make sure the power supply
connection cable and the probe cables remain separated.
2.2 INSTALLATION
Before installation, remove the front part of the box, prising with a screwdriver at point 1
(fi g.3); then lift the front part of the box as indicated in point 2 (fi g.3):
2.3 ASSIGNING OF TERMINALS
After switching off the power to the boiler, carry out the wiring using the terminal block on the zone controller (fi g.4)
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 connection 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, it is advisable 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 request heat from the generator in 3 different ways:
Therefore, fi rst of all it is necessary to select one of these 3:
