I live in a high rise condo so our heat/cool system is a boiler/cooler in the basement. I purchased the Honeywell suite pro tb6575a1000.
I had two black wires, a red wire and a beige. I hooked up the red to red, the blue to beige, brown to black and orange/yellow to black. That was exactly how the old one was done. That left the white and black from the thermostat left. I taped them individually and it doesn't work. When I turned the breaker I did not hear a pop but I have nothing on the display. Help me please!
