Using the Override/Start Button
The Override button (labeled Push To Start
on the door of the thermostat) has multiple
uses depending on the time of day when the button is pushed. One unique
feature of the T4950SCH-IAQ is that when running a program, it will not
automatically bring in occupied setpoints at the designated start time. A single
press of this Override/Start button is needed within the occupied start/stop
times in order to bring in those comfort setpoints. This allows for variable start
times in each classroom with the actual starting event being a single press of
the Override/Start button, typically by the teacher prior to the start of the day.
This button has no effect unless the thermostat is running a program so the
following only applies when the program is On:
Outside of the preprogrammed Start/Stop times for the day: the thermostat
should be in Unoccupied. A single press of the Override/Start button will
temporarily bring in occupied setpoints for the amount of time specified
in Setup Step #56. Pressing the Override/Start button again will cancel the
override timer, returning the thermostat to unoccupied settings.
Within the Start/Stop times for the day: the thermostat should enter occupied
and bring in occupied setpoints for the rest of the day until the Stop time.
If the security settings allow, the setpoints may be adjusted for classroom
comfort.
The thermostat should automatically return to unoccupied settings at the Stop
time. If the classroom is vacated early, pressing the Override/Start button for 5
seconds will bring in unoccupied settings immediately (and will show ‘OF’ for
the setpoints).
Note: During a programmed holiday, this button can only be used to override
to the occupied settings for the time specified in Setup Step #56. It is not
allowed to function as a start button since holiday settings take priority.
Viewing only connected wifi or VenNet Sensor Values
You may also view connected wifi and VenNet sensor values after pressing
ACCESSORY STATUS followed by COOLER button. Use MODE button to cycle
between readings. Note that battery strength of the battery powered sensors
can be viewed on these screens. Press ACCESSORY STATUS again to return to
normal operation.
