In addition to these three, it is possible to connect another anologue output signal for control of an
optional sequence, Y4 Extra sequence. Y4 Extra sequence is set in the same way as above. You can
also decide whether you want the output to be affected by the enthalpy control and/or the cooling
recovery.
0% at HCOut = 0%
100% at HCOut = 0%
It is also possible to split one of the three analogue outputs heating, heat exchanger or cooling into
two equal parts to give a fourth output sequence for temperature control.
5.1.1 Control modes
1. Supply air control
The supply air temperature is kept at the setpoint value by controlling the output signals for Y1
Heating, Y2 Heat exchanger, Y3 Cooling and Y4 Extra sequence. A single PI control loop is used.
The setpoint value is set using the front panel or alternatively using an external setpoint device.
Alarms for high and low supply air temperature are active.
Alarm for control offset of the supply air temperature is active.
2. Outdoor temperature compensated supply air control
The supply air temperature setpoint is outdoor temperature compensated using a control curve with
6 node points.
The supply air temperature is kept at the setpoint value by controlling the output signals for Y1
Heating, Y2 Heat exchanger, Y3 Cooling and Y4 Extra sequence. A single PI control loop is used.
Alarms for high and low supply air temperature are active.
Alarm for control offset of the supply air temperature is active.
