Automatically control dehumidification during the night

How the Opticlimate Humidistat with Light Cell Works:

The humidistat adjusts via the in-built sensor the difference between night and day, during the dark period humidity levels can spike, the sensor picks up on this change and engages the Opticlimate to correct the deficiency or excess humidity in the air.

By using the light cell, the night hours are detected so that the humidistat does not need to be connected to a timer. It should be noted that if co2 is added the excess co2 will also be drawn from the air.

Using the Opticlimate Humidistat with Light Cell:

The Opticlimate Humidistat needs to be wired into the motherboard of the Opticlimate unit, this might sound complicated but its very simple. Unscrew the face plate off the Opticlimate which will show the circuits.

The humidistat comes with tags on each wire showing where they connect onto the circuit. Simply insert these into the corresponding fittings making not of the numbers on the wires and the motherboard.

Keep the unit turned off at this time then turn back on once fully fitted.
