Cooling/Heating only fan coil unit in energyplus

For some areas cooling is only required so that there is no hot water loop. In such case, the fan coil unit in energyplus still requires to input a heating coil as I experienced with Openstudio Application 1.7.2.

I would like to know if there is a method to create cooling coil only fan coil unit.

If the heating coil is left blank, Openstudio Application will give error: Assertion coil failed on line 285 of class openstudio::model::HVACComponent __cdecl openstudio::model::detail::ZoneHVACFourPipeFanCoil_Impl::heatingCoil(void) const in file D:\OSN\src\model\ZoneHVACFourPipeFanCoil.cpp.

If the heating coil is also set but without hot water loop, energyplus will give error: " - Missing required property 'water_inlet_node_name'"

change the heating coil type to electric and turn off the availability schedule.

Thank you for the solution. I did alternatively by setting the boiler pump to 0 flow rate and deleting all the heating schedules for all relevant zones.
