Customer Question
Hi. A spot of...

Hi. A spot of trouble here. I have a Burnham Hot water system with radiators. It has two wires to the thermostat, Red and Green. I confirmed today inside the furnace red is connected to the Boiler Red and the green to boiler Green.

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

I bought a Orbit Clear .Comfort Pro, Model 83521 Thermostat wiring problem

Contractor's Assistant: Do you plan on doing the work yourself?

That is what I am doing.

Contractor's Assistant: Anything else we should know to help you best?

No heat. I told the rep at Orbit that the two wires were white and Red. She had me hook the wires up to the Thermo terminals W and R- go figure. But I was wrong!!! Not white- green.

Standard connection is red to thermostat R and if your other wire is green then conect to to W. Color coding is not always followed
