for control module setup.
Outdoor Reset Control

with a variable boiler operating tempera-
ture using the Triangle Tube outdoor sen-
sor, see pages 47 through 50 for installation
and setup.
If the installer opts for a fixed operating
temperature for the boiler system, the
outdoor sensor is not required and
should not be installed.
Additional 24V Limit Wiring
The PRESTIGE Excellence provides 24V ter-
minal connections for additional limit controls
as shown in Fig. 20 page 29. These limit ter-
minal connections will provide a "hard" lock-
out requiring a manual reset of the PRESTIGE
Excellence control, or a “soft” lockout in
which the PRESTIGE Excellence will auto-
matically reset.
