Hello. After long and bitter battle I finally admitted defeat and replaced my Waterfurnace Premier unit. I put up a good fight, replaced a blower motor and flow center over the last year; in the end, though, with federal tax credits ending this year, I gave up and replaced it with a Climatemaster Tranquility 30 unit. Hard to complain about the WF as it lasted 22 years with almost no trouble until the past year. Through the process of helping my WF limp along I've developed an interest in system performance (loop temp, pressure, flow rates, etc.) and was really looking forward to the diagnostic information transmitted to the thermostat with the new Climatemaster. However, I ordered a zoning package and the installer informed me that the Climatemaster thermostat won't handle zoning so he put in Honeywell thermostats that won't display diagnostic information. Bummer! So, my question is - is there any alternate way to access this information? I understand there is a dealer diagnostic tool available (ACDU02) but it's about $440. I'm not THAT interested. I'm wondering if anyone has developed a workaround for this? I've read enough to confirm that my installer knows his stuff, but it seems really strange that an industry leader like Climatemaster would offer one of their top end products that isn't zoning-friendly. Thanks for any advice!
