Point Name/Description
Indoor Air Quality CO2 (ppm) – The current space CO
exists either as a connected ZS sensor with CO2 or a hardware sensor connected to this
controller (Configuration >Unit Configuration > Input 1 (or 2) Function is set to IAQ
Sensor) or a value received through the Network or Linkage.
Outdoor Air Quality CO2 (ppm) – The current outdoor air CO
Configuration >Unit Configuration >Input 1 (or 2) Function is set to OAQ Sensor.
Economizer Output – The current economizer output with respect to the outdoor air
damper (if equipped).
Shutdown – When Active, all alarms are reset. (Any currently active alarms will continue
to display.) Provides a means to stop heating and cooling in an orderly manner.

Point Name/Description
Fan Mode – The supply fan's operating mode.
Options:
Auto - The fan cycles on/off in conjunction with heating or cooling.
Continuous - The fan runs continuously during occupancy and intermittently during
unoccupied periods with heating or cooling.
Always On - The fan runs continuously regardless of occupancy or calls for heating and
cooling.
Power Fail Restart Delay – How long the controller delays normal operation after the
power is restored. Typically used to prevent excessive demand when recovering from a
power failure.
Fan Off Delay – The number of seconds that the fan continues to run after heating or
cooling has ended.
Minimum Cooling SAT – In cooling mode, the cooling outputs are controlled so that the
supply air temperature does not drop below this value.
Maximum Heating SAT – In heating mode, the heating outputs are controlled so the
supply air temperature does not rise above this value.
Vent Dmpr Pos / DCV Min Pos – The minimum outdoor air damper position maintained
during occupied periods.
