I'm finally getting the install and have appreciated the help and professionalism on this board.
Question about t-stats.
- I am having an old oil forced air furnace replaced with an American Standard Comfort-R 2 stage, variable speed gas furnace (local gas company heavily subsidizes the equiptment on conversions). Do I need a 2-stage thermostat to take advantage of the 2 stage variable speed features?
- I am also have a new central a/c installation: the a/c is from the attic while the furnace is from the basement. The a/c is Trane 14xli. The contractor said that the supplier didn't have the air handler in stock that he was going to use, so instead we're upgrading to a variable speed Trane (4TEE3F40A). Seems like a good deal at an extra $400 after qualifying for the energy rebate. Same question here. Since this is a separate unit it will have it's own t-stat. Do I need a special t-stat to take advantage of the variable speed features?
Also, is this a worthwhile upgrade?
-Right now they are planning on using 2 Robertshaw 9600 digitat programmable thermostats.
Today they put in the new furnace, hung the air handler and readied the compressor. They said it should take the whole week (all new duct work in attic, new gas line in basement...)
