SPARK IGNITION TRANS-
FORMER (XFORMER) (T1)
The spark ignition transformer resides
on the furnace control (older genera-
tions of the modulating furnace have
the spark transformer mounted to a
separate ignition control). The trans-
former provides spark energy at
approximately 60 hz frequency and a
minimum of 12KV. The transformer can
be seen in Figure 29.
R-J11 CONNECTOR (J-11)
WARNING
DO NOT CONNECT A TELEPHONE
OR PHONE LINE TO THE CONNEC-
TOR (JACK) AT POSITION J-11.
DOING SO COULD CAUSE
IRREPRABLE DAMAGE TO EITHER
THE FURNACE CONTROL (I.F.C.) OR
THE TELEPHONE (OR TELEPHONE
LINE) OR BOTH.
This connector is used to program the
furnace control at the factory. It can
also be used to connect a field service
diagnostic tool. Unfortunately, this tool
was not available at the time of this
publication but should be available in
the future. Otherwise, this connection
is not to be used in the field. It should
never be connected to a telephone line
or a telephone. Doing so could dam-
age the furnace control or the tele-
phone (or telephone lines) or both.
COMMUNICATIONS
NETWORK CONNECTION
These connections are used when
installing a communicating thermostat
specified for use with this furnace.
Further, normally, thermostat connec-
tions will not be made at the 24 V
Thermostat Inputs when using a com-
municating thermostat. (Except under
one special circumstance where a com-
municating thermostat and non-com-
municating condenser are used.
See Figure 27 and the section of
this document titled SPECIAL CON-
FIGURATION – COMMUNICATING
THERMOSTAT AND FURNACE
WITH A NON-COMMUNICATING
CONDENSER.)
The terminal labeled "1" on the fur-
nace control connects directly to the
terminal labeled "1" on the thermo-
stat and "1" on the condenser. The
remaining connections follow the
same pattern.
Follow the wiring diagram in Figure
27 for connections of the communi-
cations network.
