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. Heating valve
closes.
On Call for Heat
Heating valve opens to maintain room temperature. Cooling valve
closes.
On Demand for Dehumidification
Dehumidification is achieved via cooling coil using heating coil
for reheat if necessary.
Dehumidification is only allowed in COOL mode, or if cooling is
enabled in AUTO mode.
Dehumidification is disabled if room temperature falls below low
ambient lockout temperature, which is the cooling setpoint minus
the configuration defined deadband value.
Reheat disabled if cooling demand reaches 100%.
Options
• Wireless adapter modules are available. (see Appendix B for
network wiring).
• Remote wall mount or duct sensor ready.
• Can be configured for 2-pipe systems with changeover.
• 3 universal inputs can be used and configured for advanced
