Point Name/Description
Direction Clockwise – If Damper Actuator is set to Built-in actuator, set this field
to the damper's position when it rotates clockwise.
Target Damper Position - The current damper position. To override normal
control for troubleshooting purposes, select Lock value to and then enter a value.
The damper moves to that position until Lock value to checkbox is cleared.
Auxheat - The current configured Reheat Min Damper Position. To override
normal control for reheat troubleshooting purposes, select Lock value to and then
enter a value. The damper moves to that position until Lock value to checkbox is
cleared.
Fan – The current value of the fan output relay. To override normal control for
troubleshooting purposes, select Lock value to and then enter On or Off. The relay
stays in that state until the Lock value to checkbox is cleared.
Cooling Min Damper Position – The minimum damper position the terminal
controls to when the air source mode is Cooling, Vent, or Free Cooling and the
space requirements for cooling are at a minimum. We recommend that you set
this no lower than 10%.
Cooling Max Damper Position – The maximum damper position the terminal
controls to when the air source mode is Cooling, Vent, or Free Cooling and the
space requirements for cooling are at a maximum.
Reheat Min Damper Position – For Single Duct units with ducted reheat. Set to
the desired damper position at which the reheat will provide optimum
performance. This value is compared to the Cooling Min Damper Position value,
and the greater of the two values determines the damper position.
Heating Min Damper Position – The minimum damper position the terminal
controls to when the air source mode is Heat and the space requirements are at a
minimum.
Heating Max Damper Position – The maximum damper position the terminal
controls to when the air source mode is Heat and the space requirements are at a
maximum.
Vent Position – The ventilation damper position the terminal controls to when the
air source mode is Vent and the terminal mode is not in the Heat or Cool mode. If
Linkage is not active, the zone determines vent mode by verifying that its SAT
sensor is between 65°F (18.3°C) and 80°F (26.6°C).
