Option 22 — High Cool Latch Temperature (only available if outdoor sensor is
present)
An outdoor sensor is required for high cool latch feature.
This selection is only available when Option 1 is set to H2, A2, or h2 and when
Option 7 (zoning) is set to OF (off). Configuration settings are OF (off), 80, 85, 90,
95, 100, 105, 110, On.
OF (off) — Cooling always starts in low stage (Y1) and stages up to high stage (Y1
and Y/Y2) when demand is sufficient and staging timer constraints have been
satisfied.
80 to 110_F (27 to 43_C) — Outdoor temperature above which both first and
second stages of the compressor are energized to satisfy all cooling demands. When
a cycle starts under a high cool latch, it will finish the cooling cycle on high stage.
On — The Y1 and Y/Y2 outputs are simultaneously energized to satisfy all cooling
demands.
Default is OF (off).
Option 23 — High Heat Latch Temperature (only available if outdoor sensor is
present)
This selection is only available when Option 1 is set to H2, or h2 and Option 7
(zoning) is set to OF (off). Configuration settings are OF (off), 20, 25, 30, 35, 40,
45, 50, On.
OF (off) —Heating always starts in low stage (Y1) and stages up to high stage (Y1
and Y/Y2) when demand is sufficient and staging timer constraints have been
satisfied.
20 to 50_F (- 7 to 10_C) — Outdoor temperature below which both first and second
stages of the compressor are energized to satisfy all heating demands. When a cycle
starts under a high heat latch, it will finish the heating cycle on high stage.
