Information for the specialist
The room temperature is kept at the setpoint value by controlling the output signals for the sequences. Two
PI loops are used.

Extract air cascade
Cascade control of extract air temperature and supply air temperature to achieve a constant, settable room
temperature. The extract air controller output signal (0-100%) generates the supply air controller's setpoint
value between min and max supply setpoint.
The extract air temperature is kept at the setpoint value by controlling the output signals for the sequences.
Two PI loops are used.

3.3 Temperature sequences
The supply air controller output is either a heating demand or a cooling demand depending on if the supply
temperature is over or under the setpoint. This demand is then divided into up to 4 sequences A to D. Each
sequence is configured as Heating, Cooling, Exchanger, Damper, or Not used depending on the selected
configuration.
Each sequence has it own PID-settings that can be set in the Ventilation menu in the display.
Each of these output sequences can be bound to either an analog output, to one pulse-width modulated
(PWM) digital output with a settable period time, or to a start/stop digital output.
