Humidistat for wall mounting and the possibility of Normally Open or Normally Closed contact.
The humidistat is adjusted by turning the knob on the front panel. To save power there will be up to 2.5 seconds delay before hygrostat responds to the changed position of the knob. At start-up the delay is up to 10 seconds.
When the sensor has detected that the realy should shift position, the light diode will flash at a fast pace, until the shift has taken place.
The light diode flashes at a slow pace when contacts are closed and not at all when the contacts are open.
In case of power failure the relay will remain in the last position before interruption. When restarting it may take up to 10 seconds before any need for change is detected and performed.
The humidistat has a built in hysteresis (see graph in the manual) and should not be placed in continuous relative humidity above 80%.
