3.2.7 Description of HumPower function
The HumPower is the interface between the HumSpot and the atomisers. It provides the
power for the HumSpot and the atomisers. When the value falls below the target, the HumPower receives a message from the HumSpot and connects the atomisers. When the target value is reached, the atomisers are switched off.
Various inputs and outputs are available. For the use and connection of the inputs and
outputs, see under "electrical installation", Point 5.4.3.
3.2.8 Description of maximum hygrostat function
The supplied maximum limiter must always be used. It is a safety element: in case of a malfunction in the precision hygrostat and/or external hygrostats, it limits the room humidity to
the value selected on the regulator. The target value should be set at 10% RH above the
precision hygrostats and/or external hygrostats. Upon delivery it is set at 65% RH. To
change this value, remove the screw (1), set the value required and screw it back in.

NOTE: This safety element can prevent overhumidification and thus considerable damage.
Only authorised people may be allowed to change the target value. The operator shall be
liable for ensuring that this note is complied with.
