See the ZoneHVAC:FourPipeFanCoil object documentation in the E+ Input/Output reference.
Availability Schedule:
"The name of the schedule (ref: Schedule) that denotes whether the fan coil unit can run during a given time period. A schedule value greater than 0 (usually 1 is used) indicates that the component can be on during the time period. A value less than or equal to 0 (usually 0 is used) denotes that the component must be off for the time period. If this field is blank, the schedule has values of 1 for all time period"
The fan coil will turn on when:
1) There is a zone request to serve a heating or cooling load, and
2) the fan coil is available to run per the availability schedule.
See the E+ engineering reference for more details on how zone HVAC equipment is controlled.
To determine run time, set the Capcity Control Method input to CyclingFan, and add the HVAC,Average,Fan Coil Runtime Fraction Output Variable.
