LOCKOUT TEMP:
• NONE (default)
• +5 to 55 deg F
Appears on dual fuel systems only (furnace with heat pump).
Outside temperature above which the furnace will NOT run
except for defrost. During heat pump defrost cycle, the furnace
will operate above the furnace lockout temperature. Once in
defrost, the system will satisfy the heating demand with the gas
furnace.
SETUP -- FAN COIL
HP/AC AIRFLOW:
• COMFORT (default) Cooling airflow is varied de-
pending on humidity and temperature demand settings.
This selection enables the full dehumidify and comfort
capabilities of the system. When COMFORT is not
selected, the unit will not run reduced airflows for de-
humidification. Heat Pump airflow is varied depending
on outdoor temperature to maximize comfort.
• EFFICIENCY - fixed airflow used to achieve specified
ratings - no dehumidification airflow reduction. This
is nominally 350 CFM/ton, but will vary if a 2-stage
outdoor unit is used.
• MAXIMUM - 400 CFM/ton. Dehumidify features are
not active when set to maximum.
DEHUM AIRFLOW:
• NORMAL (factory default) - When equipment is
running to dehumidify, the airflow is allowed to adjust
to a minimum to satisfy the dehumidification call.
• HIGH - Minimum airflow during the dehumidify
mode is increased to reduce duct and register sweating.
HEATER SIZE:
• (choices dependent upon fan coil model)
This will show the heater size entered during the start-up process.
This value can be changed to another value (limited by the model
number of the fan coil). If the electric heater is self-identifying,
this value is not shown.
SETUP -- HEAT PUMP / AC
COOLING LOCKOUT:
• NONE (default)
• 45 ° F.
• 50"E
• 55 ° E
Outside temperature below which cooling will not be provided.
LOW AMBIENT COOLING:
• NO (default)
• YES
Selecting YES will enable the low ambient cooling operation in
the outdoor unit. This setting is only available with
communicating outdoor units and with Cooling Lockout set to
NONE.
ENTERED SIZE:
• (dependent on indoor unit model)
Size of the outdoor unit entered during the start-up process. If the
outdoor unit is a communicating model, this value will not be
shown. This size can be changed here but is limited to sizes that
the indoor unit can handle.
DEFROST INTERVAL:
• 30 minutes
• 60 minutes
• 90 minutes
• 120 minutes (default)
• Auto-Defrost interval optimized by outdoor control
(default fnr communicating HP)
Time interval at which defrost cycles can occur on a heat pump.
ELECT HEAT LOCKOUT
• NONE (default)
• +5 to 55 deg. F
Outside temperature above which the electric heat will not
operate
HEAT PUMP LOCKOUT (BALANCE POINT TEMP):
In a dual fuel system this option will be available in place of
Electric Heat Lockout Temp.
This is the outdoor temperature below which the heat pump ,,vill
not operate.
HIGH COOL LATCH:
• NONE (default)
• 80 - 110 deg F
Outside temperature above which only the high speed (of a
2-stage outdoor unit) will run when cooling.
HIGH HEAT LATCH
• OFF (default)
• ON 2 -stage heat pump runs only high stage heating
