Hi
It is a compact schedule
Schedule:Compact,
MyTemp_SCH,
Fraction,
Through: 12/31, !- Field 1
For: AllDays, !- Field 2
Until: 24:00,0.5; !- Field 3
and i modulate this value:
EnergyManagementSystem:Actuator,
VentSchedule, !- Name
MyTemp_SCH, !- Actuated Component Unique Name large low window
Schedule:Compact, !- Actuated Component Type
Schedule Value; !- Actuated Component Control Type
IF MyOfficeTemp > 24.5,
SET VentSchedule = @MIN ((MyOfficeTemp-24.5)/2) 1 ,
ELSE,
SET VentSchedule = 0,
ENDIF;
I monitor the value of MyTemp_SCH and it behaves as expected, but the flow rate does not alter from 1.5m3/s
