Curtain Parameters
Understanding Curtain Temperature Parameters
The temperature setpoint for each curtain controls when the curtain opens. If the temperature is
warmer than the setpoint the curtain will slowly open. The temperature must drop several degrees
below the setpoint before the curtain will slowly close. The temperature deadspan controls how
much the temperature must drop before the curtains begin to close.
Understanding Curtain Cycle Time
The curtains use a cycle to control how fast they respond to temperature changes. The cycle consists
of On seconds and wait minutes. The curtain switches on for P6 seconds and then waits for P7
minutes then repeats the cycle. Adjust the cycle time so the curtain takes approximately one hour to
fully open or close.
