Thank you for your time and consideration!
I've run into an ABCD wiring puzzle! I have a Carrier
WeatherMaker infinity 58MVP100-F-1720 system with all Carrier parts including a 2 stage (supposed to be, but don't see this per wiring diagram) furnace, a single stage AC, humidifier
, dehumidification capability, and variable speed fan control. This was hooked up to an old Carrier "stock" WeatherMaker Infinity Thermidistat (controlled everything from auto switch heating and cooling to humidification, dehumidification, fan control, and coordinating with outdoor temperatures). The entire system was installed in 2004.
The wiring for the Carrier 58MVP WeatherMaker Infinity System to the old Carrier WeatherMaker Infinity Thermidistat are:
W/W1: White wire (heating)
Y/Y2: Yellow wire (cooling)
G: Green wire (indoor fan control)
R: Red wire (24 vac) "live wire"
S1: Blue wire (outdoor sensor)
S2: Brown wire (outdoor sensor)
HUM: Orange wire (humidifier)
DEHUM: Pink wire (dehumification)
C (COM): Black wire (24 vac) Neutral wire
The original old Carrier Infinity Thermidistat broke down.
Now, I bought a Carrier Infinity Touch Control (SYSTXCCITC01-A), thinking that this unit would come "wire ready" to automatically control and regulate the furnace, AC, humidifier, dehumidification, and allow for continuous fan operation (I have UV and MERV 16 filters that I like to keep running to purify the air continuously).
The new Infinity Touch Control is supposed to take care of all of this, and since all of the components are Carrier WeatherMaker Infinity components, I thought that this would be a "no-brainer".
However, the new Carrier Infinity Touch has only 6 wire terminals (ABCD + S1 and S2).
The ABCD interface is:
A: Green wire (Data A wire)
B: Yellow wire (Data B wire)
C: White wire (COM wire)
D: Red wire (24 vac wire)
S1: Optional Remote Room Sensor
S2: Optional Remote Room Sensor
There is also some sort of "Accessory Port" with very thinly spaced prongs which I am not familiar with.
I am not sure how to proceed. I have read and researched many installation manuals and checked blogs, but could not find the answers that I need.
I was thinking of attaching the "Black wire; COM wire" to the "C Terminal White COM", the "Red wire; 24 vac wire" to the "D Terminal Red 24 vac", but I do not know which wire to attach to the "A Green Data A Terminal" and the "B Yellow Data B Terminal". Also, I do not know if I should attach the Outdoor Sensor S1 and S2 wires to the "S1" and "S2" user interface terminals. Sounds like these may be remote indoor sensors.
Also, with just a simple ABCD user interface on the new Carrier Infinity Touch Control, how will it be able to control humidification, dehumidification, and fan control?
It's all still a Carrier Infinity System, but I am going from 9 wires (5 control wires + 2 hot and neutral 24 vac wires + 2 outdoor sensor wires) down to a new Carrier Infinity Touch Control with only 6 terminals (2 control terminals + 2 hot and neutral 24 vac terminals + 2 Optional Remote Room Sensor Terminals)! Wish Carrier maintained compatibility with their WeatherMaker Infinity Ideal Comfort older units, or at least give instructions on how to do it! I would like to have back the ability for the User Control to regulate everything, including heating, cooling, humidification, defumidification, and fan control.
Any assistance would be greatly appreciated!
