The extra controller can also be used for humidity control. The cooling battery will
be used for dehumidification if the room/extract air humidity is too high. The
function uses the sensor “Extra unit temp” and is placed immediately after the
cooling battery. The function also requires use of a room humidity or extract air
humidity sensor.
Example:
If the room humidity exceeds the setpoint for the function, the cooling battery will
be controlled by the external controller. The heater is controlled normally. When
the room humidity falls below the setpoint once more, the cooling control will return
to normal control. A hysteresis of 1 % is added to the function.
The function can be used for “Cascaded room temperature control”, “Cascade
connected extract air temperature control”, “Outdoor compensated room
temperature control” as well as “Outdoor compensated extract air control”.
An alarm will be triggered if “Extra controller” is in manual position or if a sensor
error occurs.
