Abstract
Devices and methods for controlling a boiler system. One illustrative method includes controlling the bypass temperature by increasing the firing rate of the boiler. Further methods include bypass temperature control methods wherein both regular and fast control methods are used, where the regular method operates to control bypass temperature by using, first, a bypass valve, and second, possible increases in firing rate. The fast control method responds to particular situations suggesting potential condensation in a primary heat exchanger to increase firing rate without waiting for a bypass valve to fully open. Further embodiments include controllers programmed for or containing programming for performing steps of the method embodiments, as well as systems incorporating such controllers.
