Connecting Honeywell thermostat to Carrier furnace

Have used the Honeywell RTH 6500 WF successfully with a hot water boiler system.

Would like to use same Honeywell with Carrier Infinity Furnace/ AC system, Model 58 MVP -080- F - 1544 Series 150 that now uses CARRIER TSTAT CC PRH 01-B.

Carrier TSTAT fed by two wire bundles coming into TSTAT.

Upper bundle has 5 wires (GR, Y, W, R, Lt BLUE).

Lower Bundle has 5 wires (GR, BLUE, W, Y & R)

TSTAT has two, six terminal, terminal boards that above bundles land on.

Upper terminal board is unmarked and following wires land on its 6 terminals (UPPER Y, UPPER W, UPPER G, UPPER R, BLANK, LOWER G)

Lower terminal board is marked from left, S2, S1, B, Hum, DeHum, C and the following wires land on the terminals:

S2 Lower Y
S1 Lower W
B Blank
Hum Lower Blue
De Hum Lower R
C Upper Light Blue

Can anyone please advise if Carrier can be controlled by Honeywell RTH 6500 WF

or, if not, is there another Honeywell TStat with WiFi that will control this Carrier Infinity.

Thanks in advance... mj fein

Welcome to the forums.

I looked up your old thermostat and from I can find it looks to be a two wire communicating thermostat. I must not have viewed the proper diagram as you are mentioning 12 terminals.

I'll let the forum pro, Houston, take this one.

Thank you Pete.

I checked the Carrier TStat again and confirmed it does have two terminal boards, each with 6 terminals.

I did have an error on the Model # of the Carrier furnace.

The Model # is 58 MVP - 080 -F - 15114 SERIES 150. Installed in 2002.

The S/N is 2802A 15343.

Any help from you or Houston would be greatly appreciated. Thanks...

I recommend using the Honeywell Redlink line of thermostats and an equipment interface module if you want to control humidification and dehumidification.

The TH8321R alone wouldn't support both humidification and dehumidification without the EIM.

An internet gateway would be required for internet access with the Redlink line.

The Honeywell Prestige IAQ would be the best choice.

Houston - Thank you for your response.

As a newbe I have a number of questions...I will go with your Prestige IAQ Redlink Kit suggestion.

1. On the drawing on your post showing T Stat, EIM, Furnace, etc....are the terminals shown on the furnace for my Carrier Infinity furnace model or just representative of a generic furnace?

2. I assume EIM is located adjacent to furnace and it wirelessly connects with T Stat. Correct?

3. My Carrier Infinity has the following terminals:

Hum
G
R
Y/Y2
W/W1
Com 24V
W2

To which terminals on EIM do I need to connect above terminals on my Carrier Infinity?

Thanks...

Just to touch on a few things....

Right now you have many wires connecting your thermostat to your Carrier unit. You will pick only two of those wires to connect the new thermostat to the EIM.

The EIM has the all the same connections as your Carrier and does get mounted near the furnace.

The HUM terminal will not get connected to your furnace. The HUM terminal of the EIM, along with a connection to C, will go directly to your humidifier.

Houston will fill you in on more details.

I would hold down the Fan button for 10 to 12 seconds to enter configuration mode and write down the existing configuration settings for the Carrier stat.

Here is the Manual to the Carrier stat.

I would get a sharpie marker an mark 1 line one bundle one red, green, yellow.....
I would then mark bundle 2 with two line....

Snap a picture or 2 of the wire connections at the stat.

I found both manuals but I'm still not sure if you have a 2 stage condenser. Are you using both Y and the Y/Y2 terminals on the existing thermostat?

Do you have an external dehumidifier or are you using the furnace dehum terminal to reduce humidity?
