The ZoneHVAC:WaterToAirHeatPump has an input field that allows a schedule to be used to control the fan operation. If this schedule is not used the fan defaults to cycling fan. The fact that the fan is Fan:OnOff does not determine whether or not the fan cycles, it's the schedule value (1 means constant fan).
From the description of the field in the IDD (the Input Output Reference has similar text).
ZoneHVAC:WaterToAirHeatPump,
A17, \field Supply Air Fan Operating Mode Schedule Name
\type object-list
\object-list ScheduleNames
\note Enter the name of a schedule that controls fan operation. Schedule values of 0 denote
\note cycling fan operation (fan cycles with cooling or heating coil). Schedule values greater
\note than 0 denote constant fan operation (fan runs continually regardless of coil operation).
\note The fan operating mode defaults to cycling fan operation if this field is left blank.
