curtain in cold curtain mode (with electric heater switched
off)
In the summer time, it is possible to switch off the electric heater and use the
air curtain
E curtain as a cold curtain (i.e.,
fan only, electric heater does not work). In this case, a simple power cut-off installation (shown in the dashed diagram below) must
be made. The installation consist in inserting any on/off switch (labelled as "G") into the control circuit between
terminal 3 on
Comfort Panel and Terminal 2 in the
air
curtain
. The on/off switch itself should be installed in a place suitable for the curtain
user.
Warning! The Comfort Panel thermostat must be set to max. The on/off switch and the wires to the switch are not included in the
scope of delivery
