Outside Temperature Compensation
1
If the outside set point is inactivated:
The curtains operate according to the curtain timer settings. There is no
outside temperature compensation.
2
If the outside set point is activated:
The controller compensates the curtain timer settings proportionally to the
outside temperature, as described hereafter.
If the outside temperature is above the outside set point:
When the curtains open, the controller increases TIME ON by 5% for
every degree that the outside temperature exceeds the outside set point
and decreases TIME OFF by the same amount.
The higher the outside temperature, the faster the curtains open.
If the outside temperature is below the outside set point:
When the curtains close, the controller increases TIME ON by 5% for
every degree that the outside set point exceeds the outside temperature
and decreases TIME OFF by the same amount.
The lower the outside temperature, the faster the curtains close.
