The Sentry controller is the central controller for the Trinity boiler. The Sentry handles all the combustion logic, together with the
energy management functions. The Sentry 2100 operates in two different modes, reset or conventional. The mode is automatically
determined by the presence of the outdoor sensor. When the Sentry 2100 detects the presence of the outdoor sensor the controller
will operate in Reset Mode, see Table 12-2. If the outdoor sensor is not installed, the controller will operate in Conventional Mode,
see Table 12-1.
