Example:
0 % Cooling at HCOut = 30 %
100 % Cooling at HCOut = 0 %
0 % heat exch. at HCOut = 32 %
100 % heat exch. at HCOut = 50 %
0 % Heating at HCOut = 54 %
100 % Heating at HCOut = 100 %
In addition to these three, it is possible to connect two additional anologue output signals for control
of optional sequences, Y4 Extra sequence and Y5 Extra sequence. ”Y4 Extra sequence” and ”Y5
Extra sequence” are both set in the same way as above. It is also possible to select whether “Y4
Extra sequence” should be affected by the enthalpy control and/or the cooling recovery.
A change-over signal can also be configured, “Y1 Heating/Y3 Cooling”.
0 % at HCOut = 0% (HCOut= Heating Controller Output)
100 % at HCOut = 0% (HCOut=Heating Controller Output)
”Y4 Extra sequence” can also be used for control of a modulating recirculation air damper. In cases
where “Y4 Extra sequence" controls a water heater battery, frost protection control may be
activated.
A change-over signal can also be configured, “Y1 Heating/Y3 Cooling”.
It is also possible to split one of the three analogue outputs Heating, Heat exchanger or Cooling into
two equal parts if an additional output function is desired.
Y4 Extra sequence, Y5 Extra sequence, Humidity control, Extra controller valve and Y1
Heating/Y3 Cooling can also be split.
There is also a pulse-width modulated digital output, ”Heating PWM”.
Its period time is settable with a default setting of 60 s.
Example:
With a controller output of 50 % and a period time of 60 s, the output will be on for 30 s and off for
30 s. With a controller output of 25 % the output will be on for 15 s and off for 45 s.
