  • Normal: Normal temperature control. (warmup, or cooldown or coast are inactive)

  • Warmup Satisfied: System is in a warmup mode, and the zone temperature is greater than the heating setpoint. The system transitions to Prmy Htg if the zone temperature drops below the heating setpoint.

  • Warmup Unreliable: Zone temperature is unreliable and warmup is requested.

  • Cooldown: System is in a cooldown mode.

  • Cooldown Unreliable: Zone temperature is unreliable and cooldown is requested.

  • Prmy Htg: Primary heating is used to warm up the space. The system transitions to Prmy Htg + Supp Htg or Prmy Htg + Box Htg (based on heating priority) if the zone temperature remains below the zone setpoint for a period of time. The system transitions to Warmup Satisfied if the zone temperature rises above the heating setpoint for a period of time.

  • Prmy Htg + Supp Htg: Primary heating is at maximum and the supplemental heating is modulated. The system transitions to Prmy Htg + Supp Htg + Box Htg if the zone temperature remains below the zone setpoint for a period of time. The system transitions to Prmy Htg if the zone temperature rises above the heating setpoint for a period of time.

  • Prmy Htg + Supp Htg + Box Htg: Primary heating is at maximum, the supplemental heating is at maximum and the box heating is modulated. The system transitions to Prmy Htg + Supp Htg if the zone temperature rises above the heating setpoint for a period of time.

  • Prmy Htg + Box Htg: Primary heating is at maximum and the box heating is modulated. The system transitions to Prmy Htg + Box Htg + Supp Htg if the zone temperature remains below the zone setpoint for a period of time. The system transitions to Prmy Htg if the zone temperature rises above the heating setpoint for a period of time.

  • Prmy Htg + Box Htg + Supp Htg: Primary heating is at maximum, the box heating is at maximum and the supplemental heating is modulated. The system transitions to Prmy Htg + Box Htg if the zone temperature rises above the heating setpoint for a period of time.
