* The 24 V AC power-supply conductors can be
connected to Terminals 60 (G) and 61 (G0) in
the control unit of the air handling unit.
** Digital temperature sensors require correct
polarity. Be careful when you wire the conduc-
tors.
*** Electrical air heater above 36 kW 440 V
and above 27 kW 230 V (Norway) demand
supply voltage 24 VAC to internal control equip-
ment. Supply voltage 24 VAC can be connected
on the AHU control unit, terminal block 60 (G)
and 61 (G0).
