METHOD OF CONTROLLING BOILER
First Claim
1. A method of controlling a boiler comprising a boiler control unit and a room controller, the method comprising:
- turning on the boiler;
setting a room-temperature-corresponding return water temperature;
setting a room-temperature-corresponding variable sleeping-time room temperature;
setting a variable sleeping-time return water temperature corresponding to the variable sleeping-time room temperature;
setting a desired room temperature using a temperature setting switch;
sensing a room temperature using a room temperature sensor;
sensing a return water temperature using a return water temperature sensor;
determining a current time using a timer; and
determining whether the current time is in a non-sleeping time zone or a sleeping time zone,wherein at the determining whether the current time is in the non-sleeping time zone or the sleeping time zone, when the current time is in the non-sleeping time zone, the boiler is controlled under a non-sleeping time zone control mode, and when the current time is in the sleeping time zone, the boiler is controlled under a sleeping time zone control mode,wherein the sleeping time zone control mode comprises comparing the room temperature sensed by the room temperature sensor with the variable sleeping-time room temperature,wherein at the comparing the room temperature with the variable sleeping-time room temperature,when the room temperature is higher than the variable sleeping-time room temperature, operation of the boiler is stopped, andwhen the room temperature is lower than the variable sleeping-time room temperature, the sleeping time zone control mode further comprises comparing the return water temperature with variable sleeping-time return water temperature, wherein at the comparing the return water temperature with variable sleeping-time return water temperature, when the return water temperature is lower then the variable sleeping-time return water temperature, the boiler is operated, and when the return water temperature is higher than the variable sleeping-time return water temperature, the operation of the boiler is stopped.

Abstract
Disclosed herein is a method of controlling a boiler. In the boiler control method, the boiler is controlled depending both on a room temperature and on a return water temperature, whereby, unnecessary operation of the boiler is minimized. Further, the boiler is controlled depending on a desired room temperature and a corresponding return water temperature in a non-sleeping time zone, and the boiler is variably controlled, in the sleeping time zone, within a variable sleeping-time room temperature range and a variable sleeping-time return water temperature range. Moreover, in the present invention, a temperature control deviation is within ±0.5° C. and a return water temperature control deviation is within ±1° C. so that the room temperature and the temperature of a floor of the room can be maintained constant. Thus, energy consumption can be markedly reduced.
