Posted July 6, 200817 yr What gauge of wire is supposed to be used for wiring an Control4 thermostat? The contractors who did my apartment used cat6 wire to connect the thermostats to my air conditioning/heating unit and it's having all sorts of problems. Since it seems likely that I'll have to hire someone else to come in and rewire I'd like to know what the recommended gauge of wire is. --Mark
July 7, 200817 yr I don't think C4 requires or recommends a specific gauge wire.Most of the time it is usually 20 or 18 gauge. I would recommend standard 7 conductor thermostat wire (White, Red, Green, Blue, Yellow, Brown, Orange).
July 7, 200817 yr we use 18/6 or 18/8 in our specs. The MOST important part of a c4 thermostat is wiring the common wire.
July 8, 200817 yr Hi Mark,I had the same issue -- the heating system just went bonkers -- kept heating the home up to almost 80 degrees even though set to 70. Why -- first the power stealing switch was set to disabled, and unfortunately now too late, did I realize that I needed a 5 wire for common in order to properly control the system.So first thing to check is the switch on the back set to disabled or enabled. And if it is disabled do you have the 5 wire for common?Now, due to the lack of 5 wire, and HVAC installed 4 wire, because they did not know -- I have to replace the CR123A battery every 1.5 months.

July 8, 200817 yr 5 Wires may have been needed for your system, but some HVAC units need more, so you should be safe with the 18/8.
July 10, 200817 yr The common wire is the MOST important part of a C4 thermostat. If the unit runs on batteries it is a horrible experience.
July 30, 200816 yr i have one of the 1st versions of the stat w/o the switch to disable powerstealing. I run a common wire and still it remains on batt power. Do you think i need a new stat?
September 17, 200816 yr punk - there was a jumper in the 1st versions. If you have a version w/o that jumper - than you have a BETA unit - and you shouldn't have it (meaning I'd call your dealer and bitch very hard at him for giving you a beta unit).
September 17, 200816 yr Shawn I remember the first units without the jumpers where you had to break off the actual circuit board. I'm pretty sure they weren't beta.
September 17, 200816 yr I'm not 100% sure Dan - but I do remember in the beta cycle it was such a large issue, that in round 2 of the beta cycle we received a 2nd unit that HAD a jumper on it. So I'm fairly certain that they never shipped w/o at least the jumper on it... but I won't bet my life on it...
September 17, 200816 yr Those original ones were so frustrating. We were barely able to make them work. We actually have a few custom beta units that c4 made for us that are still working to this day, perfectly.
September 22, 201014 yr Which one of the steps are you hung up on?It's pretty straightforward. Instal it as per the installation instructions. Add the driver. Identify the thermostat. Edited September 22, 201014 yr by ILoveC4
September 22, 201014 yr Thank u ilovec4 for ur quick response but I am very new to c4 and have learned alot for u guys but I have it already wired on the wall but need the steps to get it to identify thx.
September 22, 201014 yr Add the driver. Identify the thermostat.Those are the steps.Have you added the driver? What version are you running? If you're on Zigbee Pro and the Thermostat is running Embernet it is more involved.
September 22, 201014 yr The c4 thermostat was giving to me from a friend who just got married and bought a new home so I dont know what version that it is running I'm sure it's 2.0 tho, the rest of my component is running 2.0 firmware tring my hardiest not to call my local dealer because I have nothing good to say about them at this time.
September 22, 201014 yr Totaleclips205, do you have Composer Pro 2.0? Do NOT attempt to use 1.8 or older Composer on 2.0...you'll have issues.
September 22, 201014 yr I have the composer media and composerHe 2.0 that ive downloaded from the c4 website I do not have the Composer Pro 2.0 don't even know how to get it
September 23, 201014 yr I have the composer media and composerHe 2.0 that ive downloaded from the c4 website I do not have the Composer Pro 2.0 don't even know how to get itYour dealer will need to add the thermostat in the project for you.

August 17, 20159 yr Control4 doesn't require anything specific as far as number of wires - your thermostat and HVAC system will dictate what wires are needed and on what terminals for proper control. Just make sure you have a common wire ("C") to provide 24vAC power to the thermostat from your unit (or from a 24vAC power supply).
