I have Nest as my slave thermostat (White Rogers is still my master thermostat). All of a sudden Nest (slave) gets no power from either Rc or Rh when the master is switched from cool to heat. I switched the White Rogers (master) from heat back to cool and verified the Nest (slave) is again getting power on Rc or Rh.

Question -- how do I get the slave only to work with EWC-ST-2E on heat? Or I have to switch the ultrazone to NCM-300 even for that purpose?
