M7—Hotel, No Fan, Vacant
Set BV-81 ON and BV-64 and BV-80 OFF. The unit controls HVAC equipment to maintain space
temperature within unoccupied heating and cooling setpoints. The display is blank.
This mode’s counterpart is M6, which is activated by setting BV-64 ON.
Vacant mode offers a temporary housekeeping override function. Housekeeping can press the screen
to select override. Once at override screen, housekeeping can then press the
UP arrow, which sets the
timer to the override limit (AV-97), interpreted as minutes and fractions of a minute (e.g. the maximum
AV-97 value of 9.5 becomes 9 min. 30 sec.). When the override time is greater than zero, housekeeping
can press the
DOWN arrow, which sets the timer to zero and restores normal Vacant operation.
When active, the housekeeping override function allows changing the user-selected Rented temperature
setpoint, and the unit controls HVAC equipment to maintain the space temperature at the Rented
setpoint; the Across the Room View shows the remaining minutes and seconds of override time.
Housekeeping override can be exited by pressing the
DOWN
arrow, which reduces the remaining
override time to zero and restores normal Vacant operation.
Figure 18 M7 screen flow sequence.
M8—Hotel, Fan, Rented
Set BVs 64, 80, and 81 ON. Operation depends on whether the fan is running or stopped. If the fan is
running, the screen in the Across the Room View shows the value of occupant-selected space
temperature setpoint (AV-90) or room temperature (AV-101), alternating with the current time-of-day (if
enabled). When the unit is displaying the Across the Room View, the occupant can press anywhere on
the screen to display the Temperature screen, on which the occupant-selected space temperature
setpoint can be adjusted.
If the fan speed is set to Auto, the Across the Room View screen is blank and the temperature screen
does not allow adjustment of the space temperature setpoint.
This mode’s counterpart is M9, which is activated by setting BV-64 OFF.
