10.3. Standby mode
This mode is meant to be
used for zones which are
unoccupied for extended
periods of time.
Standby mode effectively
turns off the HVAC system
unless the system detects a
value below (5-10°c) or above
(45°c). If C35-VAV... detects
that a set point is exceeded,
the HVAC system will be
activated to protect the
controlled environment and
to ensure the temperature,
CO
2
or relative humidity
remains within the desired
setpoint range.
Similarly to Economy mode,
users will not be able to
adjust any setpoints from the
Homescreen unless Occupied
mode is activated (see
below).
Standby mode can be
activated manually using
the button or with the
Scheduler. Standby mode
will be activated if a window
contact switch is connected
and a Window is open
(optional).
NOTE : In Standby mode the
display will be turned off
after 5 minutes
A. Standby mode with manual control
B. Standby mode activated by scheduler
C. Standby mode activated by Window contact (if enabled in
parameters)
10.4. Scheduler
The week long scheduler allows users to set up to four presets for the week where the working
modes start and end at specific times. The device will automatically manage the HVAC system
to regulate temperature within the specific setpoints for each scheduled working mode
(Comfort, Economy and Standby). See page 17 for Scheduler setup.
10.5. Occupied mode
Occupied mode can override Economy or Standby mode to bring the controlled environment to
a comfortable setting with the single touch of the Occupied button on the home screen.
In these modes, the Occupied button will appear at the bottom of the home screen. When
Occupied mode is activated, the system will operate in Comfort mode and a countdown timer
will appear on the home screen. The default Occupied timer is set to 1 hour. The duration can
be adjusted in the Parameters menu (see page 22). Users will be able to adjust the comfort set
points ±3°c from the standard value for the duration of the override. By pressing the Occupied
button again Occupied mode will be deactivate and it will return to previous operating mode.
