SYSTEMAIR HR1 Humidistat RAL 9003

Art. no.: 215150

Room humidistat

A humidistat for controlling exhaust air fans in response to the relative humidity. The humidistat uses human hair as the humidity sensor medium. The set-point can be anywhere between 10 and 95% RH. Base plate in black plastic and cover in white plastic.

 

The HR1 is supplied with a sliding cover over the set-point dial, which can be locked.

 

The humidistat should be mounted in a location with good air circulation and constant temperature and humidity. It should not be fitted on external walls, walls in direct sunlight, corners etc.

 

The humidistat´s mounting holes make it suitable for fixing on to a terminal box with screws at 60 mm centres.

 

The humidistat should be precision-calibrated after it has been mounted, and should be recalibrated regularly. Dust and other matter should be removed with a soft brush at regular intervals.

 

Contacts 1 and 3 close when the air humidity exceeds the preset value.
