Abstract
An electromechanical thermostat has a fixed value voltage anticipator resistor and a variable anticipator resistor for series connection with the load. This allows a single thermostat to control either a high efficiency furnace requiring a relatively low cycle rate or a furnace of conventional efficiency which can function at a higher cycle rate. Preferably, the voltage anticipator resistor is selected to give the cycle rate required by high efficiency furnaces when the resistance of the variable anticipator resistor is set to zero ohms. If the thermostat is shipped with the variable resistor set to zero ohms, the installer will not have to adjust the variable resistor whenever the thermostat is installed in a system requiring that cycle rate.
