Abstract
A failsafe assembly for use with a thermostat that includes a housing that defines a housing interior, and first and second thermoswitches disposed in the housing interior. The first thermoswitch includes an open and a closed state and is normally in the open state. The first thermoswitch is configured to switch to the closed state when an ambient temperature drops below a predetermined lower threshold temperature and the first thermoswitch is configured to switch back to the open state when the ambient temperature rises above a predetermined first safety temperature. The second thermoswitch includes an open and a closed state and is normally in the open state. The second thermoswitch is configured to switch to the closed state when the ambient temperature exceeds a predetermined upper threshold temperature. The second thermoswitch is configured to switch back to the open state when the ambient temperature drops below a predetermined second safety temperature.
