Application

Standard on-off control of the room temperature with up to 12 relay outputs with accessory expansion modules for use with most DCA systems, where staged on-off control of cooling and heating is required. A remote temperature sensor is required. The system provides two sequencing loops, one each for heating and cooling with separate set points and throttling ranges.

Features
  • Based on the Honeywell T775L2007 Stage Sequencer Electronic Controller
  • Easy to use graphical interface
  • Adjustable set points and throttling ranges
  • Up to twelve SPDT relay outputs
  • Configurable minimum on and off times
  • Sensor calibration
  • Configurable integral and derivatives times
Selection
  • MPCT-3101: Standard control with 4 relay outputs
  • MPCT-3102: Optional control with 8 relay outputs requiring one T775S
  • MPCT-3103: Optional control with 12 relay outputs
Accessories
  • TS-W-1097 Wall mounted temperature sensor, 1097 ohm
  • TS-D-1097 Duct mounted temperature sensor, 1097 ohm
  • T775S2008 Expansion module.
