If you have selected “-1” for first zone, and last zone on
Configuration Screen #1 or if the communications is lost
with all of the zone controllers, the Zone Manager will try to
control the HVAC unit based on its Return Air Temperature.
The desired Return Air Temperature setpoints for both
cooling and heating are entered here. With this feature, if
you should want to operate the HVAC unit during
construction and the zone controllers are not installed yet
you can set Configuration Screen #1 to -1 for first and last
controllers and set the Return Air Setpoint values as desired
to operate the HVAC unit until such time as the zone
controllers are installed. After the zone controllers are
installed and operational you will need to change
Configuration Screen #1 to the actual first and last zone
addresses you have installed for proper operation of the
HVAC unit.
