Sequence of Operation and Wiring
Occupied Mode
Setpoints revert to those defined by occupied cooling and
heating. The changeover sensor sends supply air temperature to
controller.
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. Heating valve
closes. Dehumidification enabled.
On Call for Heat
Heating valve opens to maintain room temperature. Cooling valve
closes. Dehumidification disabled.
On Demand for Dehumidification
Dehumidification is achieved via cooling coil using heating coil
for 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.
Reheat disabled if cooling demand reaches 100%.
