what is the 6th wire on a honeywell zone valve
is it as i suspect not used on a w plan and can i wire a replacement 5 wire to an existing 6 wire zone valve
also is the motor and mechanical fitting on a 22mm vone valve the same as a 28mm
got a 28mm 6 core motor to replace, and today just recycled a 22mm 5 wire from another job
hoping i can save some money and install that one instead
