In D:CutOff
(In Door Day
Temperature
Cutoff)
The controller closes the valve completely when the In Door temperature average (supplied from host computer)
is higher than this set point during the Day - time between Day Begin and Day End.
(
D:ICOFF
state).
Range: 40 to 90 °F
In N:CutOff
(In Door Night
Temperature
Cutoff)
If the In Door temperature average (supplied from host computer) is higher than this set point and the time is
between Day End and Day Begin, then the valve will be closed completely.
(
N:ICOFF
state).
Range: 40 to 80 °F
InDrD_Band
Used along with ‘In Door Temperature’ parameter and ‘In Door Day(Night) Temperature Cutoff’ Set Point. This
parameter defines the allowable delta between the actual In Door Temperature and Cutoff Set Point.
Range: 0.1°F to 19.9°F with 0.1°F steps.
