AK2-SC 255 Reference Manual
Ambient: Control is based on ambient temperature.
Discharge: Control is based on discharge pressure.
(List box:)
1valve/1split: A single valve, when closed, limits
refrigerant flow to a part of the condenser, providing
two stages (usually 50%-100%).
2valve/2split: Two valves are used to provide three
stages (usually 50%-75%-100%).
2valve/3split: Two valves are used to provide four
stages (usually 25%-50%-75%-100%).
3valve/3split: Three valves are used to provide four
stages (usually 25%-50%-75%-100%).
(0.0 to 100.0) (Only with single split valves) The
temperature below which the condenser will be split.
(0.0 to 25) (Only with single split valves) The
deadband above the previous setpoint in which
"unsplitting" cannot occur.
(List box: Even, Odd) (Only with single split valves)
Which fans are dropped when condenser is split.
(List box: Yes, No) (Only with single split valves)
Whether or not condenser will be split when heat
reclaim is on.
(List box: Yes, No) Whether or not split function will
be overridden based on high discharge pressure.
(0.0 to 500.0) The pressure below which split con-
denser operation is allowed.
(0.0 to 500.0) The pressure above which split con-
denser operation is disallowed.
