    Need help replacing master and slave thermostats to z wave programmable thermostats
    Hi all!

    Im looking to replace my old thermostats with z wave programmable thermostats. I have a 3 zoned heat/ac system that has one master thermostat with wires R Y W G B O and two slaves with just R Y W. The trouble is finding a thermostat with separate B and O connections. Must installation directions speak about B and O being used for a heat pump but I do not have a heat pump system. I assume the B and O have something to do with the 3 zones and communicating to slave thermostats. Any advice? Also most of the z wave thermostats require a common wire. Can i use the G wire on the master thermostat has my common wire as long as i switch its location on the HVAC control panel?

    Thank you for your advice in advance
