Abstract
An electrical interface selectively places a heat pump and a backup temperature control device in alternative electrical communication with a single power feed. A compressor of the heat pump may be in selective electrical communication with the power feed via a normally open relay. Removal of a control voltage results in opening of the normal open relay, and closing of a normally closed relay to place the backup temperature control device in selective electrical communication with the power feed. For a ground source heat pump, a ground loop pump may also be in selective electrical communication with the power feed (e.g., via a normally closed relay).
