RE: [EnergyPlus_Support] zone temperature





I  am not sure whether the thermostat schedules are correct.

 

ZoneControl:Thermostat,
3P:3ESP Thermostat, !- Name
3P:3ESP, !- Zone or ZoneList Name
Zone Control Type Sched, !- Control Type Schedule Name
ThermostatSetpoint:DualSetpoint, !- Control 1 Object Type
Dual Setpoint - Zone 3P:3ESP; !- Control 1 Name

ThermostatSetpoint:DualSetpoint,
Dual Setpoint - Zone 3P:3ESP, !- Name
3P:3ESP Heating SP Sch, !- Heating Setpoint Temperature Schedule Name
3P:3ESP Cooling SP Sch; !- Cooling Setpoint Temperature Schedule

3P:3ESP Heating SP Sch, May-Jun-Jul-Aug-Sep Jan-Feb-Mar-Apr-Oct-Nov-Dec h9-20 22°C
3P:3ESP Cooling SP Sch May-Jun-Jul-Aug-Sep h9-20 24°C -- Jan-Feb-Mar-Apr-Oct-Nov-Dec h9-20 22°C

I have not seen this format before.

Why setpoint-temperatures are not maintained in the zone?
The plant is into file : UTA
The control is:
