INSTRUCTION AL230A
Room temperature controller
AL230A is a room temperature controller for use in air handling or
demand-controlled ventilation applications.
It controls a 0...10 V output signal with a PI algorithm in direct or
reverse action. The output signal is applied to an air handling unit,
e.g. a ventilator such as an EC fan or damper.

unit is forbidden.
Installation
Place the device in a location that has a temperature representative
for the room. A suitable location is approx. 1.6 m above floor level in
a place with unobstructed air circulation.To remove the front cover,
use a 3 mm flatblade screwdriver to depress the locking tongue in
the lower part of the casing (
picture 1
). Press and twist the screw-
driver, and at the same time pull the bottom part of the front outwards
(
pictures 2-4
). When the bottom end of the front cover is free from
the bottom part of the casing, slide the cover towards the top of the
casing to free the hooks holding the upper edge of the front cover
(
picture 5
). Perform the connections according to electrical wiring
diagram. Cables must be fixed using the 2 cable ties supplied as indi
-
cated in
picture 6
. Screw the bottom part of the casing to the wall.
Disconnection
AL230A should be connected to a switch or circuit breaker in the
building installation. This switch should be in close proximity to the
controller and within easy reach of the operator, and should be
marked as the disconnecting device for the equipment.
Always use the circuit breaker to disconnect the controller from the
mains supply during maintenance of the EC fan or damper.
Settings
The direction of the output signal is set using the JP1 jumper

The range of the voltage applied to the ventilator is defined using the
MIN and MAX knobs. MIN is used to define the minimum applicable
voltage to the ventilator (0...5 V), while MAX defines the maximum
voltage (5...10 V). The PI controller will then operate between the
relevant MIN and MAX values.
Example 1:
If the MIN value is set to the minimum position and MAX to the
maximum position, the PI controller will work from 0...10 V.
Example 2:
If MIN is set to 2 V and MAX is set to 7 V, the PI controller works
from 2 to 7 V.
