Question 1

Will this work with with 2 wire from the wall configuration? My setup has only 2 wires line voltage configuration. If it will work how do i wire them?

Accepted Answer

Yes it does. I replaced an old 2-wire Honeywell setup with this unit, and it worked just fine. The extra wires are for fan control (low, med, high). Look for my product review, which includes installation pics.

Accepted Answer

I cannot answer, but the Honeywell, customer service line may be able to.

Question 3

What's the difference between tb6575a, tb6575b, and tb6575c model? i need to replace an old (1960) 3-wire, 120v heat/cool fan coil unit in my condo.

Accepted Answer

For my 1970 style Firstco fan coil, I replaced an old Honeywell 3 wire line volt thermostat with the TB6575A1000 SuitePro.  Since my replaced my fan coil with a new model, but with a 3-speed motor, I connected the three speeds to the thermostat and it works fine.  The answer to your question is below:

Question 4

Is this a Redlink thermostat?

Accepted Answer

No. Not Redlink and totally different from the Redlink ones which are for typical single family homes (heat pump or conventional HVAC systems). This thermostat is for 120V fan coils, small units located in apartments or offices, that are served by a large central plant.
