wiring to fan coil
Sequence of Operation and Wiring
Occupied Mode
Setpoints revert to those defined by occupied cooling and heating.
Stand-by Mode (only available when PIR motion detector sensor is used)
Setpoints revert to those defined by stand-by cooling and heating.
Unoccupied Mode
Setpoints revert to those defined by unoccupied heating and cooling.
Occupied Override Mode
System reverts to occupied mode for duration determined by “ToccTime” parameter.
On Call for Cool
Cooling valve opens to maintain room temperature.
On Call for Heat
Electric heat operates to maintain room temperature. Cooling valve closes and dehumidification is disabled.
On a Demand for Dehumidification
Dehumidification achieved via cooling coil using reheat if necessary.
Dehumidification only allowed in COOL mode or if cooling is enabled in AUTO mode.
Dehumidification disabled if room temperature falls below low ambient lockout temperature, which is cooling setpoint minus
configuration defined deadband value.
