FourPipeFanCoil actuators for external control
Dear All,
I'm trying to control with actuators a ZoneHVAC:FourPipeFanCoil
since now I was able to control the mass flow rate with the following actuator:
EnergyManagementSystem:Actuator,
m_42, !- Name
ZONE1 FAN COIL UNIT SUPPLY FAN, !- Actuated Component Unique Name
Fan, !- Actuated Component Type System Node Setpoint
Fan Air Mass Flow Rate; !- Actuated Component Control Type Mass Flow Rate Setpoint
I have tried to control the out temperature from the heating coil with the following actuator but I was not able to achieve it:
EnergyManagementSystem:Actuator,
t_42, !- Name
ZONE1 FAN COIL UNIT SUPPLY OUTLET, !- Actuated Component Unique Name
System Node Setpoint, !- Actuated Component Type
Temperature Setpoint; !- Actuated Component Control Type
Any Idea on how I can control the air temperature outlet?
I'm able to do it in an air terminal with AirTerminal:SingleDuct:ConstantVolume:NoReheat
like the following :
AirTerminal:SingleDuct:ConstantVolume:NoReheat, ZONE2 Single Duct CAV No Reheat, !- Name On 24/7, !- Availability Schedule Name Air Loop Zone Splitter Outlet Node 3, !- Air Inlet Node Name ZONE2 Single Duct CAV No Reheat Supply Outlet, !- Air Outlet Node Name 433.830000; !- Maximum Air Flow Rate {m3/s}
By controlling the flowing actuators:
EnergyManagementSystem:Actuator,
t_41, !- Name
AIR LOOP AHU HEATING COIL AIR OUTLET NODE, !- Actuated Component Unique Name
System Node Setpoint, !- Actuated Component Type
Temperature Setpoint; !- Actuated Component Control Type
EnergyManagementSystem:Actuator,
m_41, !- Name
AIR LOOP AHU SUPPLY FAN, !- Actuated Component Unique Name
Fan, !- Actuated Component Type System Node Setpoint
Fan Air Mass Flow Rate; !- Actuated Component Control Type Mass Flow Rate Setpoint
