N322-RHT-24V Temperature & RH Controller 24 V

The N322RHT is a digital controller for relative humidity and temperature. Its 2 relay outputs can be configured independently as control or alarm, either for temperature or relative humidity. A Relative Humidity and Temperature or RHT probe (3 m length) is provided along with the instrument

The temperature, humidity and status of relays are shown on the LED Display.

Each relay output has configurable set point, hysteresis and action. Relays can trigger above or below setpoints, within or outside temperature ranges. On and off times are configurable.

Relay outputs can drive fans, compressors, pumps, heaters etc. to control the temperature and humidity.

Applications include fruit storage and air conditioning.


  • RHT sensor probe with 3 metre cable included
  • Dual independent relay output
  • Bright, 3.5 digit LED display
  • Adjustable hystereses and configurable setpoint minimum and maximum limits
  • Configurable password protection
  • IP65 when installed in a panel
