Re: [EnergyPlus_Support] Heating not responding to Control Strategy





Or do you have any warnings that two setpoint managers are writing setpoints  to the same node? Did you try the helpdesk?

Hi modellers

I am running a model with several zones. It seems to me that there is some component in the heating system that is not responding to the control strategy. The attached graph illustrates the problem (heating not working). Any hint about what may be not working?

graph_heating not working

This zone is controlled as follows:
----------------------------------------------
SetpointManager:Scheduled,
    Air Loop Setpoint Manager,           !- Name
    Temperature,                         !- Control Variable
    29_deg_heating,                      !- Schedule Name
    Air Loop Supply Side Outlet 2;       !- Setpoint Node or NodeList Name

same also applies for the cooling cooling airloop the schedules are always fixed for AllDays at 29 and 14 degress C (heating and cooling outlet air temperature)
------------------------------------------------
AvailabilityManager: Scheduled
these are always on
------------------------------------------------
Schedule:Compact,
    always_4,                !- Name
    Any Number,              !- Schedule Type Limits Name
    Through: 12/31,          !- Field 1
    For: AllDays,            !- Field 2
    Until: 24:00,            !- Field 3
    4 ;                      !- Field 4

Zone temperatures are controlled by a thermostat set to the DUAL setpoint mode
-------------------------------------------------
ThermostatSetpoint:DualSetpoint,
    Z11_1_DEPARTURES_LD Dual SP,  !- Name
    Z11_1_DEPARTURES_LD Heating Setpoint Schedule,  !- Heating Setpoint Temperature Schedule Name
    Z11_1_DEPARTURES_LD Cooling Setpoint Schedule;  !- Cooling Setpoint Temperature Schedule Name


the heating setpoint schedule is the following, 20deg. C and setback at 12deg.C
Z11_1_D
