Control modes > Extract (summer) else supply air |
This temperature control mode combines Extract air cascade and Supply air outdoor compensated modes.
Summer/winter mode function is utilized for switching.
In summer - extract air cascade mode is active and extract temperature controller generates the setpoint for the supply air temperature controller.
In winter - supply air outdoor compensated mode is active. Setpoint for supply air temperature is determined by outdoor temperature and dependency curve.
