The
FAN ON/AUTO
button will shift the fan operation from continuous to cycling
with a call for heating or cooling. If the fan is left in the
FAN ON
mode during
occupancy, it will automatically shift to
AUTO FAN
during Setback.
The
CHECK
button is used to cancel any safety time delays. These time delays
are to protect the equipment from short cycling, and to prevent multiple HVAC
systems from coming on at the same time after a power failure or with the lights.
If you see the word
DELAY
flashing, then the Lightstat
TME
is in a time delay.
The startup time delay can be as long as 12 minutes.
