G Terminal
This setup option selects desired operation when the R--G circuit
changes state on the furnace control board depending on setup.
S
DISABLED (Default)
S
FAN -- turns on fan to selected fan speed when G termi-
nal is energized. See Fig. 26.
S
FAN SPEED -- select Low, Med, High for all zones
when G terminal is energized
S
SHUTDOWN -- shuts off fan and equipment when initi-
ated. This function 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. 27.
S
GEN (generator input) -- displays GENERATOR MAL-
FUNCTION pop--up message when G is energized. This
function requires the addition of a Generator Self Test
Verifier (Part No. GSV200) which must be purchased
separately. Visit
www.GeneratorVerifier.com
for details
and ordering information. See Fig. 26.

HP/AC Airflow:
S
COMFORT (default) Cooling airflow is varied depend-
ing on humidity and temperature demand settings. This
selection enables the full dehumidify and comfort capa-
bilities of the system. When
COMFORT
is not selected,
the unit will not run reduced airflows for dehumidifica-
tion. Heat Pump airflow is varied depending on outdoor
temperature to maximize comfort.
S
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 out-
door unit is used.
S
MAXIMUM -- 400 CFM/ton. No dehumidification air-
flow reduction.
Dehum Airflow:
S
NORMAL (factory default) -- When equipment is run-
ning 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 opera-
tion 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.
