The controller compares room temperature with an adjustable set point (knob) and regulates a 0..10 V proportional integral INTERNAL 1 SIGNAL in direct or reverse action based on jumper JP1 setting:
JP1 closed 1-2 = heating (reverse action) JP1 closed 2-3 = cooling (direct action)
The controller compares also CO2 with an adjustable set point (SW3) and regulates a 0..10 V proportional INTERNAL 2 SIGNAL in direct action.
The output signal applied to a ventilator is the maximum between INTERNAL 1 SIGNAL and INTERNAL 2 SIGNAL.
The range for temperature knob set point is from 5 to 30°C
