摘要:
A method for automatically operating a heating system includes operating a thermostat at a set point having a default set point value, automatically receiving an indoor temperature signal from an indoor temperature sensor, automatically receiving an outdoor weather indicator signal representing a measured or predicted outdoor weather condition, based on the outdoor weather indicator signal, determining a factor affecting heat flow out of water pipes adjacent to an indoor space, comparing the factor affecting heat flow to a pre-determined freeze protection point, based on the comparison, determining whether to maintain the set point at the default set point or to raise the set point to a computed set point higher than the default set point, and using the thermostat to automatically control the heating system.
摘要:
A method for automatically operating a heating system controller for heating an indoor space so that the indoor temperature measurement signals are kept a) at approximately or above a default set point when the automatically obtained outdoor temperature indicator signals reflect an outdoor temperature indicator that is above a freeze protection point, or b) at approximately a computed set point that is higher than the default set point when the outdoor temperature indicator signals reflect an outdoor temperature indicator that is below the freeze protection point. The computed set point can be based on an outdoor temperature indicator. A heating system comprising a furnace, a thermostatic controller, a sensor of indoor temperature operatively connected to the thermostatic controller, a receiver operatively connected to the thermostatic controller for receiving a signal indicative of an outdoor temperature indicator, wherein the thermostatic controller is configured to operate according to the method.

摘要:
A method for controlling a heating system is disclosed. The method comprises obtaining a reading for a temperature of a wall cavity in a structure served by the heating system for an indoor space adjacent to the wall cavity, determining an equivalent wall cavity temperature (ET), and when ET is less than or equal to a threshold temperature (TT), selecting a chosen set point by selecting a default set point (DS). When ET is less than TT, the method comprises determining a calculated set point (CS) based on the ET, comparing the CS to the DS and a maximum set point (MS) and selecting the chosen set point by selecting DS if CS is the DS, CS if CS is between DS and MS, MS if CS is above MS; and controlling the heating system to regulate the temperature of the indoor space according to the chosen set point.
