Heat/Cool Filter
Use this parameter to dampen the response of the heat or
cool output. The output responds to a change by going to
approximately two-thirds of its final value within the spec-
ified number of scans. A larger value results in a slower re-
sponse to changes in the process variable.
Values: 0 (off) to 255
Default: 3
Modbus Address (Loops 1 to 9): 40239 to 40247 (heat) or
40256 to 40264 (cool)
Parameter Number: 14 (heat) or 15 (cool)
LogicPro Driver: Database
LogicPro Address (Loops 1 to 9): 14.1 to 14.9 (heat) or
15.1 to 15.9 (cool)
Hysteresis
Specify how much the process variable must deviate from
set point before the output can switch between on and off
(for on/off control) or switch between heating and cooling
(for heat/cool control).
Values: See Table 5.13 for values and decimal placement.
Default: See Table 5.13
Modbus Address (Loops 1 to 9): 40856 to 40864
Parameter Number: 54
LogicPro Driver: Database
LogicPro Address (Loops 1 to 9): 54.1 to 54.9
Decimal Placement for Modbus or LogicPro: See Dec-
imal Placement for Numeric Values on page 80.
