This temperature control mode combines Room cascade and Supply air outdoor compensated modes.

Summer/winter mode function is utilized for switching.

In summer - room cascade mode is active and room 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.
