– indicate stage 2 or 3 are required to maintain the desired temperature.
These LEDs will not blink they will remain constant.
WARNING:
The remote manual mode interface feature is intended to temporarily turn on “Manual”
mode (full fan speed) for added s
afety regardless of the position of the “Auto/Manual” toggle switch
on the status board. If the unit was previously in “Auto” mode it will return to “Auto” mode when the
remote dry contact opens. If it was in “Manual” mode the blower heater will remain in “Manual” and
should be switched back to “Auto”. The unit should never be left in “Manual” mode since the heating
capacity of the unit is based on preset airflow rate and continuous duty in “AUTO” mode.
