OPERATION

For proper selection of settings, follow the boiler manufacturer
recommendations.
High Limit Controller
R-B terminals provide high limit switching function (contacts
open at set point on temperature rise). (See Figures 30 and 31).
R-B terminals shut off burner if water temperature exceeds high
limit setting. Burner restarts when temperature drops to high
limit setting, less differential.
NOTE: On manual reset models, the reset button on the front
of the case must be pushed in to allow the burner to
operate after a high limit shutdown.
