Pretreatment
Damper and pump control for preheating or precooling of the outdoor air via an underground
intake channel.
Cooling recovery
If the extract air is colder than the outdoor air and cooling is required, the heat exchanger
control is reversed in order to return the cool extract air.
Recirculation control
Recirculation of air using a supply air fan and (optionally) extract air fan and a recirculation
damper with or without temperature control. Used as a recovery function or during heating
with support control during the night. Recirculation control is available as an analogue or a
digital function.
Step controllers Heating/Cooling
As an alternative to the analogue control of ”Actuator heating Y1” or ”Actuator cooling Y3”
step controllers can be used for controlling heating or cooling in steps using digital control.
Change-over
In 2-pipe systems where a combination heater/cooler is operating together with a heat pump,
Change-over is a function that enables using the same pipe for both heating and cooling,
depending on which is currently required. It uses the output Y1 Heating/Y3 Cooling.
