Damper enable signal
As long as the outside air temperature is below the value of OAT-03 and the coil return water temperature sensor is not configured, the heating coil will enable the damper after the delay, as defined by parameter DME-01.
As long as the outside air temperature is below the value of OAT-03 and both return water and coil off temperature sensor are not configured, the valve will be set to the position as defined by the parameter FEZ-03 and is returned to its normal control position via a ramp function defined by FEZ-04.
As long as the outside air temperature is above the value of OAT-03 plus the fixed differential of 1K, the coil will enable the dampers immediately (without delay).
To disable the damper enable alarm even at low temperatures, set DME-01 to a value of "0".
