Abstract
The invention provides a boiler control system based on delayed cycle control, in which the control is implemented by interrupting a heating device enable signal (such as a BMS enable signal). This means the system can be used with electronic boilers without the boiler being aware (in terms of generating error codes) of the control taking place.
Claims18
A boiler control system for controlling a heating device in a boiler, comprising:
- a delayed cycle controller for activating and deactivating said heating device based on an upper temperature threshold and a lower temperature threshold;
- a temperature sensor for measuring a boiler temperature;
- an interrupt unit for interrupting a heating device enable signal thereby to implement the delayed cycle control of the delayed cycle controller, wherein the heating device enable signal is a signal externally input to the boiler which takes priority over an internal thermostatic control of the heating device in the boiler.
A method of controlling a boiler heating device, comprising:
- sensing a boiler temperature;
- activating and deactivating said heating device based on an upper temperature threshold and a lower temperature threshold to provide delayed cycle control, wherein the upper temperature threshold and lower temperature thresholds are below the internal upper and lower thermostat control settings of the boiler, such that the internal upper thermostat control setting is not reached;
- interrupting a heating device enable signal thereby to implement the delayed cycle control.
