Bryant Dual Fuel Tstat w/ 80 plus furnace
I have a bryant plus 80 system (installed 98') with a CAC\BDP N coil. I have a thermostat that apparently is a Dual Fuel type. Model TSTATBHPDF01-A, at first I thought is was a HP model but when I give it power to it displays DF on bootup. I currently use a Honeywell programmable battery operated tstat that is too hard to read. I like the idea that this tsat is a bryant (same manuf), large buttons with a large backlit LCD screen that will auto change from heat to cool and doesn't need batterys that need to be replaced. I live with my GF father and he is aging with eye problems so I felt that this might help him in the years to come when he will be living alone. I pulled in a new line for the common as well as another line for the outdoor temp sensor. But all documents on these types of thermostats (programable AC, Hp, 2S) indicate that they will do both AC and heat pump applications (except the AC model) I really want this tstat to work for him and me as I have put in many hours of time pulling new wires and obtaining the outside temp sensor. I can't find any info on this exact model number, but what I have found is a close relative to it (carrier). The Hp models state that they will control a AC system so why wouldn't the DF model also? The 4 dips inside are...
A: on = Zoning B: on = Conventional Recovery (Last 2 are on a sticker covering the print on the circuit board) C: on = No low temp. lockout D: on =2 speed, Off =1 speed The info I have found on the DF models all show a large display with the outside cover closed, but this one does have large display but only when outside cover is open. Meaning outside door opens to reveal the rest of the info on the lcd. Thanks for your time in helping me salvage mine! Druce |

Been repairing HVAC equipment for 3 years now and have finally hit one that stumps me. It is a Bryant 355AAV FAU paired with a Bryant 180ANA CU. Upon arrival the fuse on the FAU is blown, so I disconnect the stat and CU and ohm out the low voltage 4 wire connection to make sure no wires are...
Hello there, I have a Rheem furnace and is only one year old. Recently my furnace didn't come on so I had someone come out and look at it and it turns out it was the defrost board on the heat pump that was bad. I replaced the board with a new one and turned the system on and it worked on heat and...
I have a single stage heatpump. I changed the tstat out yesterday to a new hunter manual tstat, worked fine last night.
