Questions & Answers

Can I install it myself?

or do I need a hvac person to do it
Asked by: Julie
JULIE, THIS IS DANGEROUS TERRITORY FOR A MAN. I CAN ONLY SAY THAT IF YOU ARE HANDY AND HAVE DONE ELECTRICAL WORK, THEN YES.THERE ARE 5 WIRES THAT NEED TO BE PROPERLY CONNECTED IF USED FOR HEATING AND AIR CONDITIONING.THE MOST COMMON MISTAKE IS DISCONNECTING THE JUMPER OR GETTING THE WIRES CONNECTED IN THE WRONG PLACE.I WOULD SUGGEST MOVING UP JUST A FEW DOLLARS AND BUYING THE DIGITAL ONE. THE WIRING IS THE SAME SO THAT DOES NOT CHANGE THE ORIGINAL ISSUE. ADVICE?GET A HANDYMAN OR HVAC PERSON TO DO IT.

does this run in electric?

I had an old mercury one and the gas co. took it out and replaces it with a digital one and when my lights go out I don't have heat. I want one that works without elect. So I can be warm even with no lights. Help please. I have had this a few years and I live on a slab so it gets cold fast and I worry about the pipes freezing in the winter without heat.

I bought a ct87n thermostat and can't get it to work

the manuel didn't say how to hook this up if you only have 2 wires so I went to the on line manuel. It said to hook the wires to R & W . It still doesn't work. I got a second thermostat thinking the first one was defective but it still doesn't work. I am using this on a gas fireplace . How can I make this work ?
Asked by: Randy
You may have blown the transformer at the furnace or a fuse at the furnace. You need to check voltage at the wires, you should have 24v if not you may need a technician to come out if you are not familiar with furnaces

does it make any clicking noises or any sound at all when the heat or cool come on (like a relay sound) ?
Asked by: Shawn
I'm happy to be able to answer your question, regarding any "clicking noises" and this thermostat. The answer is no. We've had this exact thermostat for many years. We briefly tried the digital, and we didn't like the complexity of the digital thermostat. I'm thrilled we found the same one again! This one is a pleasure, and there are no sounds of any kind related to its operation. It is so easy to use and it is quite accurate.
