4. SETTINGS ON THE C5 CONTROLLER

Initial zone setup is done from the computer connected to the AHU directly, via local network or internet. This can be done

by authorized service personnel only.

If zone control function was not ordered in advance and if it was not activated from the factory, at first it is needed to log in

to the “Factory” level and activate one or two additional zones.

If zone control function was ordered in advance and if it was activated from the factory or in a way described above, log in

into the “Service” level and navigate to “Functions screen”. Enable which additional zones will be used. For the control of

independent temperature zones or pre-heater (see application examples in section 1), check mark option “Independent”

and enter desired temperature setpoint.
