Product Code: E914
The E914 will accurately control the humidity of an area to a fully adjustable relative humidity setpoint between 5% and 95%, combined with an adjustable relative humidity hysteresis (differential) of anything between 1% and 10%.
The humidistat offers greater flexibility and control with a semi-automatic on/off pushbutton. In the ‘on’ state the humidity level will be regulated to the setpoint until the room user disables the humidistat by pressing the pushbutton to select the ‘off’ state.
LED indicators illuminate to signal which state the humidistat is operating in. After a pre-selected number of hours in the ‘off’ state (any time between 1 and 15 hours is selectable), the humidistat will automatically revert back to the ‘on’ state, ensuring that control of the room humidity is again restored.
This unit is supplied as a robust and tamperproof unit which includes a die-cast aluminium case and tamperproof screws.

Remote Sensor (/RS)
