Featuring two modulating analog outputs, four individually programmed relay outputs and two temperature inputs this is for special DCA dehumidifier applications requiring modulating control of auxiliary heat and on-off control of cooling where the heater supply air temperature must be limited or controlled. A remote temperature sensor is required as well as a heater leaving air temperature sensor.

  • Easy to use graphical interface
  • Individually adjustable set points, differentials and throttling ranges
  • Two analog outputs with selectable 0-10VDC, 2-10VDC and 4-20mA signals
  • Four SPDT relay outputs
  • Configurable minimum on and off times
  • Sensor calibration
  • Configurable integral and derivative times
  • MPCT-3401 Control of SCR type electric heat (0 to 10 Vdc)
  • MPCT-3402 Control of modulated gas duct furnace (0 to 10 Vdc)
  • MPCT-3403 Modulated hot water valve (2 to 10 Vdc)
  • TS-W-1097 Wall mounted temperature sensor, 1097 ohm
  • TS-D-1097 Duct mounted temperature sensor, 1097 ohm
Control of SCR type electric heat (0 to 10 VDC)
