The HR1 is a humidistat with potential free switching contact response to the relative humidity in the ambient air. It features an adjustable set-point that can be anywhere between 10 and 95% relative humidity. The HR1 is supplied with a sliding cover for the set-point dial, which can then be locked. Contacts 1 and 3 close when the air humidity exceeds the preset value. The humidistat has mounting holes that make it suitable for fixing onto a terminal box with screws at 60mm centres. After it has been mounted, the humidistat should be precision-mounted and recalibrated regularly.
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, or corners. Dust and other matter should be removed with a soft brush at regular intervals.
