I found the communicating Thermostat very easy to install and use. I couldn't run a new thermostat 18gauge wire to the air handler due to shared condo walls. I only had 4 wires existing and that's not enough to do the 24 volt thermostat. Using existing 18g wire from old non-communicating Trane unit made the thermostat install almost too easy. The directions state it's supposed to be a shielded wire, but mine works as its not near any 240 v wire or other power wire. I installed the ACiQ ducted 2ton unit and the amount of money I saved in electricity is amazing.
I’m about to install one of these for the first time so I am grateful you saved me from frying the PCB. Can these outdoor units be used with a Goodman air handler?
Where's the air handler install instructions? We had to switch SW1-1 and SW1-4 dip switches both to the ON position, in the air handler, in order to use a 24v thermostat, ecobee.
FYI I would keep my low voltage wires aways from 240v load wires to avoid induction currents. Like in your video just move yellow and white wires away, move the supply black wires to the right.
Thanks for sharing! I found it difficult to understand how the wiring was supposed to be hooked up from the paperwork with a thermostat.... (without using the signal cable to my indoor air handler). I have a 3 ton ACIQ unit with a 10KW Style Crest indoor air handler unit. I have not installed any of it as of this date.
Hi, Why is the recommended setup the 24v thermostat but the instructions later say that the included communicating thermostat is the most efficient? How much efficiency am I losing?
Can you still run the unit on a 24V thermostat and still connect signal between the indoor and outdoor unit so they can communicate? This way I can run a Ecobee thermostat and not lose some of the efficiency gains by having the units communicate between each other.
Where does the s1 and S2 wire go to and what gauge wire does it need to be? And if I have th2 s1 and s2 hooked up, do i need to hook up the thermostat wires too?
On my QCiQ 4 ton ducted heat pump the terminal for S1 and S2 are clearly marked. BE AWARE that both install manuals I received with the heat pump warn against using S1 and S2 terminals only under certain circumstances or the board may be damaged. Also says to NEVER apply 24v power to S1 and/or S2. You might want to call whomever sold you your heat pump for technical advice.
@@geraldhenrickson7472 Thanks for replying and I should have better worded the question. I have the same setup in the video above for terminals S1 S2 B W D in class 1 and R C Y1 Y2 L in class 2 for my ACIQ heat pump. I was wondering where the S1 and S2 wire connection from the heat pump go to? And if I have the 24 V thermostat wires hooked up like yours ( I see you have a red, blue, black and yellow wire in video), does the S1 and S2 still need to be hooked up in addition to thermostat wires or no?
What’s the advantage of using the communicating thermostat?

vs straight electric heat? i bet. What's the percentage if you had to guess, saved?
What about the dip switches for 24 volt thermostat ?

Thank you for the great videos !
