I have a Rheem Rpnl-030jaz heat pump with a Rheem RHPL-HM3621JA vari speed air handler. I want to get a thermostat for this that I can check house temps when I am away. I was looking at Honeywell redline stuff. If I am right it looks to me that I would need a HZ432 a True zone and a wireless t-stat and a wireless adapter set-up. Does this sound right? Is there another brand that does the same thing for a better value?
