This setting will adjust the furnace’s airflow to compensate for
altitude. Altitude adjustment is not available with older furnaces.
Please see furnace instructions for further details.
Setup -- Fan Coil
Heat Pump Heating:
S
COMFORT (default) Heat Pump airflow is varied depending on
outdoor temperature to maximize comfort.
S
EFF 325 -- Fixed airflow used to achieve specified ratings . This
is nominally 325 CFM/ton, but will vary if a 2--stage outdoor
unit is used.
S
EFF 350 -- Fixed airflow used to achieve specified ratings . This
is nominally 350 CFM/ton, but will vary if a 2--stage outdoor
unit is used.
S
MAXIMUM -- 400 CFM/ton.
Heat Pump Cooling Airflow:
S
COMFORT (default) Cooling airflow is varied depending 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 dehumidification. Heat Pump airflow is
varied depending on outdoor temperature to maximize comfort.
S
EFF 325 -- fixed airflow used to achieve specified ratings -- no
dehumidification airflow reduction. This is nominally 325
CFM/ton, but will vary if a 2--stage outdoor unit is used.
S
EFF 350 -- 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.
S
MAXIMUM -- 400 CFM/ton. No dehumidification airflow
reduction.
S
QUIET-- minimum cooling airflow that the system can safely
run (typically 300 CFM/ton). Use this setting if duct noise is a
severe problem. Note that duct sweating in high humidity
environments could be an issue.
Dehum Airflow:
S
NORMAL (factory default) -- When equipment is running to
dehumidify, the airflow is allowed to adjust to a minimum to
satisfy the dehumidification call.
S
HIGH -- Minimum airflow during the dehumidify mode is
increased to reduce duct and register sweating. Also increases
minimum airflow during normal cooling operation to reduce
duct sweating.
Heater Size:
S
(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.
Elect Heat Lockout
S
NONE (default)
S
+5 to 55

F (--15 to 13

C)
Outside temperature above which the electric heat will not operate
except for defrost.
G Terminal
This setup option selects desired operation when the R--G circuit
changes state on the fan coil control board depending on setup.
S
DISABLED (Default)
S
FAN -- turns on fan to selected fan speed when G terminal is
energized. See Fig. 23. This setting is used in conjunction with
fresh air supply products (e.g. fresh air make--up air dampers).
S
FAN SPEED -- select Low, Med, High for all zones when G
terminal is energized
S
SHUTDOWN -- shuts off fan and equipment when initiated.
This function is not intended for emergency fire shutdown. It
may be activated by a dry contact from an external device such
as a float switch or a relay. User selects whether the contact is
NC -- normally closed (default) or NO -- normally open. User
Interface displays SYSTEM MALFUNCTION on screen and
registers G terminal shutdown event in Last 10 System Events.
See Fig. 24.
Dehum Drain
Turns off the continuous fan at the end of cooling for five minutes
in order to drain the indoor coil of water. The fan will only be
turned off if a dehumidify demand existed at the start of or during
the cooling cycle. Default is enabled.
Reheat Dehum
Enables electric heat to be used while Cool to Dehumidify is
running. This will allow the Cool to Dehumidify function to run
much longer greatly improving humidity control in cooling mode.
Accumulated electrical energy used while reheating (in
kilowatt--hours) is shown on the Fan Coil Run Hours screen and
can be reset there. This is only available with fan coil systems.

Low Ambient Cooling:
S
NO (default)
S
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
. Low
ambient kits are not needed with communicating outdoor units.
For detailed sequence of operation, see outdoor unit installation
instructions.
Entered Size:
S
(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.
