CONNECTION TO THE MAINS
1. Make sure that the sectioning device at the beginning of
the unit’s power line is opened, locked and equipped
with a signal.
2. Open the general line disconnecting switch (if present)
3. Verify that the net is in conformity with the data shown
in the registration plate placed on the electrical board.
4. Check the dimensional drawing for the input of the
electrical lines
5. Take away the closing plate placed on the electric
board (ONLY IF PRESENT) and drill a hole through it
to pass the cables through)
6. Protect the cables, using the fairlead of an adequate
size.
7. Using the layout of the electrical diagram, single out the
connecting terminals of the electrical supply cables, of
the neutral (if foreseen) and the PE protection cable
8. Connect the cables to the relevant terminal boards
9. Before supplying power to the unit, make sure that all
the safety devices that were removed during electrical
connections are positioned again.
FUNCTIONAL CONNECTIONS
Use voltage-free remote control devices that are suitable to commutate very low loads
(12V, 10mA)

Few inputs must be activated by configuration parameters whose access is reserved to
authorized assistance centers (in order to avoid unauthorized modifications)
ON / OFF FROM REMOTE CONTROL
It allows the remote start and stop, not by keypad.
It can be used to disable the unit during the night, the weekend etc., so with ON or OFF periods relatively longs (some hours).
It has not to be used with ON or OFF cycles too much shorts: they compromise the operating logic and they can cause
malfunctions or faults. In summer operating, for example, ON –OFF cycles lower than one hour can compromise the
thermoregulation logic, that implements an integral check.
If this function is not used, jump the respective terminals.
SIGNALIZATION OF MALFUNCTIONING/ UNIT FUNCTIONING
Remote signalization of the proper function (ex. green light) or signalization of blocks of the machine (ex. red light).
Maximum voltage at the terminal ends is 24v ac and maximum power is 5a (ac1)
SECOND SET-POINT
It allows the use of a secondary set-point, such as, for example, for a night operation, which can be activated by a remote
contact.
When the contact is CLOSED, the secondary set-point is activated.
DEMAND LIMIT
It is possible to limit the absorbed electric power with an external signal of 10 Vcc or 4-20 mA. The higher the signal is, the
lower the number of compressors available to meet the thermal need.
Only an authorised service centre can perform the parameter configuration.

FRESH AIR TEMPERATURE PROBE -
Optional
It allows the automatic correction of the set-point according to the external air temperature.
For example, the summertime with low external temperatures, it is possible to have the internal comfort even with set-points
higher than the standard.
The parameter configuration must be carried out by an assistance center.
