Further information
⚠ In order to ensure the expected status of the
relays, please check that the device is
connected to the main power supply before
energizing the power circuit.
For a 4-pipe fan coil, the cooling valve should
always be connected on the left side and the
heating valve on the right side. Before the start-
up of the device, it must be assured that the valve
is completely closed.
The fan and the valves to be connected must
have the same nominal supply voltage.
Outputs that are not being used for valve control
can be used as individual outputs or shutter
channels.
