Series HS Humidity Switch
Programmable, 8 Amp Relay, 3-Digit Relay
 

The microprocessor based Series HS Humidity Switch provides control for humidifying or dehumidifying. Relative humidity, output status, and error messaging can be viewed on the bright green LED. The switch features 9 user defined parameters including setpoint, hysteresis, control type, cycle time, and probe adjustment. Access to programming parameters can be locked for security purposes using the password protection feature. Use the configuration key (sold separately) to quickly program multiple units. The Series HS includes a fitting clip for panel mounting, gasket, rear terminal cover, and instruction manual.  Dimensional Information
