Customer Question
I am replacing a...

I am replacing a thermostat - the new one is a Honeywell RTH 7600. The old Honeywell thermostat did not have any labels for the wire connections. The wire colors in my system are red, blue, white and green. Does the blue connect to the "C" terminal?

Contractor's Assistant: I'll do all I can to help. Is there anything else important you think the HVAC Technician should know?

Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

Standard color coding would put red on R (jumper to RC), white on W, green on G and blue on Y. Best to check the other end of the thermostat lead where it connects to the furnace. But the above is what I would expect.

Well - it didn't work - makes sense that it would.
HVAC Technician: Rick, HVAC Supervisor replied 2 years ago

Why are you changing the thermostat?

Customer reply replied 2 years ago
we have a two zone system. the downstairs thermostat kept showing "hold" and was no longer adjustable, so I decided to replace both.
HVAC Technician: Rick, HVAC Supervisor replied 2 years ago

What do you have for heating equipment? do you have zone dampers or is this hot water baseboard heat?

natural gas- both thermostats connected to a Trol A Temp Model TZ-3 total zone controller
HVAC Technician: Rick, HVAC Supervisor replied 2 years ago

Ok, I'm not familiar with that zoning system. I'm going to open this up to my colleagues so one of them can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.
