3.1 INSTALLING THE POWER SUPPLY PROVIDED
For the device to function correctly, the power supply provided in the package must be used.
It can be placed inside a junction box or secured to the wall or to another support through the screw slots.
Some units have panels which, in addition to holding the control board, are arranged to house the power supply inside
the unit itself.
In these cases, for the 230Vac connection, use the terminals L1 and N of the control board (see the unit installation
manual).
The fastening holes are identified by a rectangular hole.

3.2 AUXILIARY RELAY
The Connect CRP has an auxiliary relay with voltage-free NO contacts, able to take a maximum load of
5A - 250Vac.
This relay can be used to control (for example) a zone valve. It closes when the set point of the Connect CRP, in
thermostat mode, is such as to require the system to be switched on, i.e. in heating when the set point is higher than
the room temperature and, in cooling, when the set point is lower than the room temperature
.
