- 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.

. To override
normal control for reheat troubleshooting purposes, select
Lock value to

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%.

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.
