Outdoor Temperature Limit
1. The PRESTIGE may operate with a vari-
able boiler operating temperature using the
Triangle Tube outdoor sensor, see pages 48
through 50 for installation and set-up.
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 provides 24V terminal con-
nections for additional limit controls as shown
in Fig. 20 page 32. These limit terminal con-
nections will provide a "hard" lockout requir-
ing a manual reset of the PRESTIGE control,
or a “soft” lockout in which the PRESTIGE
will automatically reset.
