A bug report.
When we select VariableFanVariableFlow
or ASHRAE90VariableFan
for Capacity Control Method
of HVACTemplate:Zone:FanCoil
, we get the following severe error and the simulation terminates.
** Severe ** GetFanCoilUnits: ZoneHVAC:FourPipeFanCoil: SPACE1-1 FAN COIL
** ~~~ ** ...the fan type of the object : SPACE1-1 SUPPLY FAN does not match with the capacity control method selected : VARIABLEFANVARIABLEFLOW please see I/O reference
** ~~~ ** ...for VariableFanVariableFlow or VariableFanConstantFlow a Fan:SystemModel should have Continuous speed control.
It is because Speed Control Method
of Fan:SystemModel
is set to Discrete
in the expidf file. Speed Control Method
should be Continuous
.
You can easily reproduce the bug using ExampleFile HVACTemplate-5ZoneFanCoil.idf (V22-2-0).
We can edit Speed Control Method
in the expidf file manually, but I hope Continuous
is automatically selected when we run idf files with HVACTemplate:Zone:FanCoil
.
