erminal

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) -- d isplays 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.

Minimum amount of time low stage must operate before high stage

is activated. Ten to 60 minutes. 10 = default

A demand of 5_F/2.8_C or more will override the staging timer.

Amount of time the blower will continue to run after heating has

shut off.

Setup -- Fan Coil

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.
