The Standard Display of box temperature and setpoint for 3
zones is shown in Figure 3. The unit is running in Continuous
Mode. Zone 1 has a setpoint of -10°F, and a return air
temperature of -8.2°F. The downward pointing arrow shows
this zone is cooling. Zone 2 has a setpoint of 35°F, and a return
air temperature of 35.1°F. The absence of an arrow indicates
that this zone is in null. Zone 3 has a setpoint of 50°F, and a
return air temperature of 48.8°F. The upward pointing arrow
shows this zone is heating.
NOTE: The zone temperature shown is always return air
temperature.
Pressing the soft key under each zone allows the setpoint for
that zone to be changed. In addition, the soft keys under Zone 2
and Zone 3 are used to turn those zones on and off. Pressing the
soft key under MENU accesses the MAIN MENU.
NOTE: Zone 1 is always on when the control system is
