1.6.2.1 Door open in 'room unoccupied' mode
If the door is left open, the occupancy state will remain as unoccupied regardless of
whether or not motion or another in-room event is detected. There is however also
a run state in the thermostat which is based on the set-point/guest setting. The run
state works differently depending on whether the open door is interior or exterior,
see details below.
If the open door is configured as an interior door (i.e., opens to another air conditioned
space), the thermostat will operate based on the guest setting as long as motion
or another in-room event is detected. Each time an in-room event is detected, the
‘Room not occupied’ timer will restart. If the ‘Room not occupied’ timer elapses without
motion or another in-room event being detected, the thermostat will maintain the room
temperature based on the unoccupied setback temperatures.
If the open door is an exterior door (i.e., opens to a non-climate controlled space),
the thermostat will turn off after the ‘Room not occupied’ timer expires regardless
of whether or not motion is detected.
Note: If the exterior door timeout is set to ‘Short’, the thermostat will turn off the
air handler after 20 seconds. See chapter 4 Thermostat profiles list, section Under
the Timeout tab, for details about setting the exterior door timeout.
1.6.3 Room unsold
To achieve more energy savings when the room is not rented, the setback is deeper
than when the room is rented but unoccupied. The system will enter the unsold setting
when the room has been unoccupied for the duration of the configurable ’Room not
sold’ timer. In the unsold mode, the temperature is based on the unsold setback
temperatures.
Note: If using an online system, the room will immediately enter the unsold mode upon
receiving a check-out command from the property management system (PMS) or at
guest card expiration.
Note: The unsold mode gives the greatest potential for energy savings. For this reason,
the online system allows for maximum energy savings as the room does not need to
wait until the ‘Room not sold’ timer elapses to enter the deep setback mode.
1.6.3.1 Door open in 'room unsold' mode
Similar to the door open condition in the unoccupied state, the thermostat will control
the temperature based on the guest setting when an interior door is open and motion
(or any other in-room event) is detected for a period of time equal to the ‘Room not
occupied’ timer. If the timer elapses with no further detection of in-room events,
the thermostat will revert to maintaining the room temperature at the unsold setback.
If an exterior door is left open, the thermostat will turn the air handler off.
