Appendix C: RTU Open Points/Properties on the Equipment Touch
Point Name/Description
Supply Fan VFD – The current commanded output to the VFD to control the fan's speed
if Fan Control is set to Variable Speed.
Space Temperature - Prime Variable – The space temperature value currently used for
control.
Supply Air Temperature – Displays the current supply air temperature.
Outdoor Air Temperature – The outdoor air temperature used for control.
Space Relative Humidity – The current space relative humidity if a valid value exists
either as a connected ZS sensor with RH 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.
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.
