Typically one or more regular batteries must be installed to operate it, although some so-called “power stealing” digital thermostats use the common 24 volt AC circuits as a power source, but will not operate on thermopile powered “millivolt” circuits used in some furnaces. noblex Tue, 13 Jul 2010 08:39:32 GMT
