3 Operation
The system is operated via the ON / OFF
switch in combination with the 3-position
switch for the required fan power. Both
switches have no indication of their switch
position. The optional temperature
controller permits selection of the required
temperature.
As an option the integral fresh air valve can
be actuated using the OPEN / CLOSE switch.
When it is open the control light in the
switch (Compact Cooler 8) will be lit.
If the roof-top air-conditioning system
Compact Cooler 8 has been installed with
optional heating, the heating will be
switched on via a combined heating / air-
conditioning switch. The two-position ON /
OFF switch for the air-conditioning system
(top right) will then be replaced by the
combined heating / air-conditioning switch
(bottom right).
