Heat pump room temperature control heating (HpuTRCtlH11)
Overview
The application function "Heat pump room temperature control for heating 11 " (HpuTRCtlH11 ) is the hub for the sequencing of the room temperature controllers for FCU heating. It determines the room heating setpoint and the room heating demand signals to maintain the room temperature at the heating setpoint.
The following devices in the room segment(s) are supported:
- Heating coil
- Radiator
- Heating/Chilled ceiling
- Heating/Cooling coil
- Fan
Function
This AF works in collaboration with a room segment HVAC device component heating AF. The heating room temperature PID controller is enabled based on a signal that is read via the grouping function (from equipment in the room segment) indicating whether heating is available.
Temperature sequence order: 1) Radiator, 2) Heating ceiling, 3) Heating/Cooling coil, 4) Heating coil, 5) Fan heating (only for serial fan operation)
