Programming curtain control relays
Curtains control the temperature by adjusting air flow into the facility, with the idea that more air
cools the building.
How curtains work
Curtains hold their position while the temperature is within the
idle band
of the
set point
. For
example, if the
set point
is 80°F and the
idle band
is 4°F (+2°/–2°), the curtain holds its position
when the temperature is between 78°F and 82°F.
If the temperature rises above the
idle band
(above 82°F in our example), the curtain opens for the
open run duration
. After opening, the curtain holds its position for the
open idle duration
. If the
temperature is still above the
idle band
, the curtain again opens for the
open run duration
and the
process repeats.
If the temperature drops below the
idle band
(below 78°F in our example), the curtain closes for the
close run duration
. After closing, the curtain holds its position for the
close idle duration
. If the
temperature is still below the
idle band
, the curtain again closes for the
close run duration
and the
process repeats.
