Initiating occupancy mode:
commercial use
This feature keeps temperature at an energy-saving level
until you touch Press to start occupancy. When you arrive,
touch the button to maintain a comfortable temperature
while the room is occupied.
Fig. 111.
Touch the or buttons to set the temperature or the
Hold Until time. The temperature is maintained until the
time you set. Temperature returns to an energysaving level
after the timer expires, or the “Occupied” period ends.
NOTE: This feature is available only when programmed
by the installer.
Remote setback: commercial use
During Occupied program periods, an occupancy sensor
directs the thermostat to go to REMOTE SETBACK
settings when the room is empty. If someone is in the
room, it uses the Occupied program period settings. The
thermostat ignores the occupancy sensor during
Unoccupied program periods.
If the thermostat is set up to be non-programmable, the
sensor directs the thermostat to go to REMOTE SETBACK
settings when the room is empty. If someone is in the
room, then it follows the settings set by the user.
Depending on how your thermostat was installed, it may
delay for up to 30 minutes before switching to REMOTE
SETBACK settings. This delay allows the room to stay
comfortable if the room is unoccupied for only a short
time.
Adjusting humidification settings
1. Touch MENU and select Humidification.
Fig. 112.
2. Select Auto.
3. Move the slider bar to select humidity level.
Fig. 113.
4. Touch More Settings if frost or condensation
appears on the windows. Use a lower number to pre-
vent frost or condensation. Use a higher number if
indoor air is too dry. Window Protection limits the
amount of humidity to prevent frost or condensation
on windows. See notes below.
