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
