Abstract
The present disclosure relates to an apparatus for automatically shutting down a boiler system when it is not needed (e.g., during warm weather) based upon calls for heat output by a temperature control element (e.g., thermostat) within a facility. The apparatus has a temperature control element that provides calls for heat to a controller when a temperature within a facility is below a setting value. The controller controls operation of a boiler, having a medium with a temperature between a low limit and a high limit, in response to the call for heat. A monitoring element determines a prevalence of calls for heat and selectively adjusts the low limit based upon the determined prevalence of calls for heat. Therefore, when calls for heat are less frequent the monitoring element will reduce the low limit to reduce fuel consumption of the boiler.
