ABSTRACT:
A thermostat for controlling the temperature within a space to be conditioned includes a system mode selector switch for selecting one of the heating, cooling or off modes of operation and a blower mode selector switch for selecting an automatic (cycling) or continuous mode of operation for the blower for blowing air into the confined space. Within the thermostat are heating actuating switches for one or more stages with associated anticipators and a cooling actuating switch with associated anticipator. An ambient compensating thermistor and a fixed resistor in series therewith are associated with the thermostat. Enhanced outdoor temperature compensation is provided by an outdoor positive temperature compensating thermistor in series with a variable resistor, which are arranged in parallel with the fixed resistor.
