Application

Featuring on-off control of the temperature with four individually programmed relay outputs this system is standard for control of pool water temperature on most DCA pool water heating dehumidifiers. It is also used for staged control of outdoor air and exact replacement for older T775 controllers. A remote temperature sensor is required.

Features
  • Based on the Honeywell T775B2040 Staged Electronic Controller
  • Easy to use graphical interface
  • Individually adjustable set points and differentials
  • Up to four SPDT relay outputs
  • Configurable minimum on and off times
  • Sensor calibration
Selection
  • MPCT-3201: Pool water control
  • MPCT-3202: Outdoor air control from entering air temperature
  • MPCT-3203: Replacement for old T775B1026
Accessories
  • TS-W-1097 Wall mounted temperature sensor, 1097 ohm
  • TS-D-1097 Duct mounted temperature sensor, 1097 ohm
