6 - ELECTRICAL CONNECTIONS
WITH A PERMISSIBLE TOLERANCE
Make sure that the sectioning device at the beginning of the unit’s power line is opened, locked and equipped with a signal.
Open the general line disconnecting switch (if present)
Verify that the net is in conformity with the data shown in the registration plate placed on the electrical board.
Check the dimensional drawing for the input of the electrical lines
Take away the closing plate placed on the electric board (ONLY IF PRESENT) and drill a hole through it to pass the cables
through.
Protect the cables, using the fairlead of an adequate size.
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
Connect the cables to the relevant terminal boards
Before supplying power to the unit, make sure that all the safety devices that were removed during electrical connections are
positioned again.
FUNCTIONAL CONNECTIONS
FOR ALL CONNECTIONS REFER TO THE WIRING DIAGRAM ENCLOSED WITH THE UNIT
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
Generally the unit is delivered with bridged terminals; if the control is not used, the bridge should not be removed.
CHANGING FROM SUMMER TO WINTER USING THE REMOTE CONTROL
Only if the hot water coil or electric heaters are present.
This function is activated with the RemMode = 1 parameter.
Selection switch open – unit in heating mode, selection switch closed – unit in cooling mode, this way the keyboard or su-
pervisor unit selection is deactivated.
SET ECO USING THE REMOTE CONTROL
This function is activated with the RemMode = 1 parameter.
In this way the keyboard or supervisor unit selection is deactivated.
VENTILATION ONLY USING THE REMOTE CONTROL
This function is activated with the RemMode = 1 parameter.
In this way the keyboard or supervisor unit selection is deactivated.
FIRE ALARM INLET
Generally the unit is delivered with bridged terminals; if the control is not used, the bridge should not be removed.
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).
