Figure 22: Dehumidier control
If the humidity rises above the SP, then dehumidication is started via a DO signal to a dehumidier.
If the humidity drops below the SP – Humidity dierential, then dehumidication is stopped.
Heating function (application 4 only)
The heating function is used to prevent the temperature from becoming too low, e.g. in a cold room, etc. The limit
for when the heating function cuts o is set as an oset value below the current cut-out limit for the refrigeration
thermostat. This ensures that refrigeration and heating do not occur simultaneously. The dierence for the heating
thermostat has the same value as for the refrigeration thermostat. To prevent that the heating thermostat cuts in
during short-term drops in air temperature, a time delay can be set for when to change from refrigeration to
heating.
