Product Code: E915
The E915 offers a calibration-free, high quality solution to tamperproof humidity control. It utilises a high-accuracy humidity sensor in conjunction with its robust die-cast aluminium case and tamperproof screws to ensure vandal-resistant yet accurate tamperproof energy control.
The E915 regulates to a fully adjustable relative humidity set-point between 5% and 95%, combined with an adjustable relative humidity hysteresis (differential) of anything between 1% and 10%.
The humidistat provides accurate humidity control by controlling loads of up to 10A such as ventilation, humidification and dehumidification equipment.
Robust Range Variants:
Remote Sensor (/RS)
Remotely located humidity sensor. This unit is ideally suited for use within ventilation ducts.
24 Volt (/24V)
Powered by 24 volt (AC or DC) supply.
