ABSTRACT OF THE DISCLOSURE A space thermostat for controlling the two-stage operation of both heating and cooling apparatus includes two single-pole, double- throw mercury type switches operatively connected to a single bimetallic coil. One switch energizes stage one of the heating apparatus when tilted in one direction and energizes stage two of the cooling apparatus when tilted in the other direction. The other switch energizes stage two of the heating apparatus when tilted more in the direction which effected the energizing of stage one of the heating apparatus and energizes stage one of the cooling apparatus when tilted less in the direction which effected the energizing of stage two of the cooling apparatus. The switches are adjustably mounted with respect to each other so that the differential between stages can be adjusted to be the same as the dif- ferential of each switch. With the differential between stages so adjusted, the energizing temperature of stage one of the heating appara- tus and the energizing temperature of stage one of the cooling apparatus are automatically the same, a feature which simplifies the calibration of the thermostat. Printed circuit boards, attached to the switches, contain a portion of the internal wiring so as to reduce the amount of loose wiring.
