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 (D) when the automatically obtained outdoor temperature indicator signals reflect an outdoor temperature indicator that is at or above a freeze protection point (FPP), or b) at approximately a computed set point (C) that is higher than the D when the outdoor temperature indicator signals reflect an outdoor temperature indicator that is below the FPP. The C 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, and 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 said method. |
