PLEASE NOTE THAT THE ACK42 MOTOR IS DOUBLE INSULATED SO THEREFORE DOES NOT REQUIRE AN EARTH CABLE
Multiple window motor connections
It is possible to connect multiple window motors in parallel up to a maximum
load of 5A, allowing more than one window to be controlled simultaneously.
The motors should normally be wired to terminals 1, 2 & 3 of the 7 pin
connector.
Radio Antenna
The radio antenna wire must not be shortened. To achieve the best reception
range, the antenna would ideally be arranged in a straight line (not coiled
or scrunched up), pointing directly away from the controller and not adjacent
to any other metalwork or wiring. In practice, this arrangement will usually
be impossible to achieve. Try different arrangements of the antenna wire and
range-test the remote control to find an acceptable solution.
Software/ Operation
When electrical power is first applied, the software version is displayed
for about 5 seconds:
Press the Auto key to switch to Auto from any other command mode if necessary.
In t`his mode the controller tries to maintain a steady ambient temperature
by fully opening and closing the window according to the desired and measured
temperatures.
The first figure (+24°C) is the desired temperature.
Hold down the SET key and use the up and down arrow keys to adjust the value.
The second figure is the measured temperature.
The prefix ‘T’ can change, indicating alternative measured temperature
data.
· ‘T’ indicates live data from the remote thermometer,
the preferred source.
· ‘t’ (lowercase) indicates live data from the on-board
thermometer. This feature is provided in case the remote thermometer fails
or becomes disconnected.
Note that after power-up, once the controller has established communication
with the remote thermometer, the on-board thermometer is disabled.
· ‘@’ indicates the controller is using the most recent
valid data in the event of both thermometers failing.
The display is updated at roughly 5 second intervals.
The controller uses two methods to reduce any nuisance caused by the window
constantly opening and closing:
1) It applies a ±1°C deadband around the desired temperature,
the window state is not changed while the measured temperature remains within
the deadband.
2) The window state is only updated at roughly 60 second intervals, except
when a rain sensor is installed and rain is detected, in this case the window
closes immediately:

For security reasons, the controller needs to be taught the unique electronic
serial number of a new keyfob before it will respond to it. To learn a new
keyfob:
1. Remove mains power from the controller and wait a few seconds until the
display goes blank.
2. Hold down the set key while reapplying the mains power.
The display confirms that the controller is in learning mode:
The controller also exits learning mode if no valid keyfob
code is received within 60 seconds.
Up to 8 individual keyfobs can be recognised by the controller, each keyfob
must be learned separately by following the above procedure.
All learned serial numbers can be erased if necessary by applying mains power
while holding down the Auto key.
The display confirms that the controller has erased all the codes:
