Multiple Installation (Ecopower only)
To Master/Slave two or more air curtains together the remote control is plugged into the
Master unit and a RJ lead should be connected from the Master to the Slave unit(s).
Thermoscreens 3m RJ extension leads are available and must be ordered separately.
Additional air curtains, up to a maximum of eight units, may be connected as indicated
below. For Master/Slave configuration an independent mains supply as per Table 2 must
be supplied to each air curtain.
Ecopower Controller Motherboard
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.
