Hello! Lurker finally turned poster here. I'll make this short and sweet... Does my brand new Carrier GT system have the turn key desuperheater installed AKA can I buy a second electric tank for preheat, plumb it in and start it up? The part number decodes as having a desuperheater, but I'm still anxious. Carrier says they can't give very much info to a homeowner and you have to contact a local installer. Can one of you pros please confirm? This is an install in a new construction house, never even been turned on yet. Long story short, I don't trust the builder due to major problems with this build, and I don't trust their subs, plus the sub puts me in contact with a bitchy project manager there and she is terrible at answering my questions. I can't get prices through the sub, I have to go through the builder. It took me several months for them to tell me a second tank with desuperheater would be an extra $4k. Lulwat..!?!? If the option is factory installed it should be as simple as a second cheap tank and some plumbing... Needless to say I declined their factory install and I'm looking to have a plumber friend do it after I move in soon. I just want to triple check that they didn't somehow neuter my geo unit and I lose out on the desuperheater ability. I took the access panels off the unit and looked around. There is a water in and out on the side with the loop in/out, plus those go to some sort of unit labeled 'Turbotec Refridgerant Heat Reclaimer" and there appears to be some type of pump driving the whole thing. First intuition says, great that seems like a desuperheater! Here's my concern: I found the parts, but I don't see the correct switches referenced in the manuals on the control panel inside. The documentation I found (manuals) speak of a 'SW21' and others that need flipped to turn on the system, test it, or adjust water temp. I don't see those exact labels on my board. If mine does have the desuperheater like I think it does, can someone shed some light on what needs flipped on my board since it doesn't have the traditional names? Here's my model info: GT036VTLCDET1XX1 (D should equal desuperheater) Here are some pictures of the unit: If anyone can help shed some light on if this unit has a turnkey desuperheater and most importantly help identify the controls that would be most helpful! Thank you!
