Humidistat

The HT Series setpoint relay models offer thermostat or humidistat functionality. Two separate relays can be configured to control heating and cooling when in thermostat mode, or humidifying and dehumidifying when in humidistat mode.

HT models are calibrated with NIST traceable calibration equipment. Analog output models feature a keypad to make adjusting humidity and temperature setpoint values easy. They transmit the setpoint values back to a control system by means of dual outputs.A slide-switch allows easy selection of output type, either 4 to 20 mA or 0 to 5 V/0 to 10 VDC signals. Dual outputs enable effortless control of both humidity and temperature in a single.
