Installation Manual

Only available if outdoor sensor is present or Wi-Fi weather is setup for the high cool latch
feature.
This selection is only available when SW1 is set to H2, A2, or h2 and when SW7 (zoning) is set
to OFF. Configuration settings are OFF, 80, 85, 90, 95, 100, 105, 110, On.
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 110F (27 to 43C) — 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. If the cooling equipment is energized to
satisfy a dehumidify demand only (no cooling demand), the latch will not be applied.
ON — The Y1 and Y/Y2 outputs are simultaneously energized to satisfy all cooling demands.
Default is OFF.
SW23 —High Heat Latch Temperature (only available if outdoor sensor is
present)
This selection is only available when SW1 is set to H2, or h2 and SW7
(zoning) is set to OFF. Configuration settings are OFF, 20, 25, 30, 35, 40, 45, 50, On.
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 50F (-7 to 10C) – 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.
On — The Y1 and Y/Y2 outputs are simultaneously energized to satisfy all heating demands.
Default is OFF
SW24 —Programmable/Non--Programmable
This selection allows the installer to configure the Thermostat as either programmable or non-
programmable. Selections are P, nP.
Default is P.
SW25 —Number of Programmable Periods
This selection allows the installer to configure the Thermostat for two or four periods per day.
Two periods is a common commercial application and four periods is more common for
residential. This selection is not available if SW24 has been set to nP to configure the Thermostat
for non—programmable operation.
