Function Control Comments Standard
Fan Heat Interlock –
The heat output is governed by the
fan speed. If low or medium fan
speed is selected the heat output
will operate on only first heat stage.
Second stage heating will only
operate on high fan speed.
DIP1 Option Suitable on vertical electrically
heated Designer air curtain.
Maximum heat output achieved if
maximum fan speed selected.
Independently set-up DIP switch
on each mother board. This
feature operates in manual or
auto mode. As supplied, the
default setting would
be for heat and fan
settings to be
independent (
DIP1
OFF).
Disable Fan Run-on –
Disable fan run-on.
DIP2 Option
(LPHW &
Ambient only)
Must only be used for LPHW and
Ambient air curtains.
Independently set-up DIP switch
on each mother board. As supplied, the
default setting would
enable fan run-on
(
DIP2
OFF).
Thermostat Master –
Only the air sensor thermistor in
the master air curtain will be used
for measuring the reference air
temperature for the whole
master/slave installation.
DIP3 Option
The air sensor thermistors in all
the slave air curtains will be
ignored. This will then avoid
situations on larger doorways with
master/slave air curtains where
some units can blow cold air
whilst others can blow warm air,
because they currently all refer to
their own air sensor for control of
the heat output of each air
curtain.
The master air curtain need not
be the one that the wall control is
plugged into. This dip switch
setting must also be used for
Global Switching (Master/Slave)
via the INHIBIT terminal – see
next page. As supplied, the
default setting would
be for the air sensor
thermistor on all
units to be
measuring
(
DIP3
OFF).
Overheat Fan Disable –
If DIP4 is on and thermal cut-out(s)
operate both heat and fan circuits
are isolated and LED’s on wall
switch flash. If DIP4 is off and
thermal cut-out(s) operate, only the
heating circuit is isolated and the
LED’s on the wall switch flash.
DIP4 Option
(Electric only) Independently set-up DIP switch
on each mother board.
To remove fault, isolate electrical
supply to air curtain, reset TOC
and reconnect supply.
As supplied, the
default setting would
enable fan if TOC
trips (
DIP4
OFF).
Fan run-on time set two minutes. Built-in If “FAN ONLY” has been
selected, at switch off, no fan run-
on.
