The air handling unit lighting is controlled by a switch
mounted on the cover of the control panel on the air hand-
ling unit. The switch is connected to a quick connector in
the control panel.
Lighting control in the control panel
Connect the power supply for the air handling unit light-
ing via the terminal block on the power unit, see page 4–5.
For 5.5 kW power units, L3 and L3’ are strapped on the
terminal block for the lighting power supply via the air
handling unit power supply. For 7.5 and 11–15 kW power
units, L3 and L3’ are strapped downstream of the fuse,
see pages 4–5. Note that in this case the lighting power
supply is also cut when the air handling unit power
supply is cut. Connect the external power supply to the
lighting in accordance with the wiring diagrams on pages
7-9. This allows lighting even when the power to the air
handling unit is cut.
