Notes
Fan heat interlock
Allows fan speed to govern heat
output on electric heated units.
If low or medium fan speed is
selected, a lower heat output
results. High heat operates only
on high fan speed.
DIP 1
ON
Heat output is
governed by fan
speed.
This feature is only used with
electric heated air curtains to
limit very high air
temperatures.
Set DIP1 to OFF if unit is
water heated or ambient.
Disable fan run-on
The 2 minute fan run-on after
switch off is enabled or disabled
on electric heated air curtains.
DIP 2
OFF
Fan run-on at
medium speed
enabled.
Must only be used for water
heated or ambient air
curtains. Each air curtain
must have DIP2 set to ON for
no fan run-on.
Thermostat master
For master/slave installations.
Only the air sensor in the
thermostat master air curtain is
used to measure air temperature.
Set DIP 3 to ON in the air curtain
that will be the master unit.
DIP 3
OFF
Air curtains in
master/slave
systems all act
independently.
Air sensor thermistors in all
slave air curtains will be
ignored.
Stops some units blowing
cold air and others blowing
warm air in master/slave
systems on larger doorways.
