Thermostat Installation and You!

You’re a do-it-yourself kind of person. You’ve done your fair share of home improvements and appliance installation. You know your way around a crescent wrench. You don’t need any help when it comes to thermostat installation.

You’ve got this. You’ll be fine. Everything will be fine. No reason to panic.

Right?

Improper Thermostat Installation & How It Can Ruin Everything

Everything could go wrong, but probably not in the way you’re thinking. While it’s possible to mess up the wiring of the thermostat, that’s not the most common installation problem. The most common way people make mistakes during their thermostat installation is all about location, location, location.

Not Too Hot, Not Too Cold

Here are some thing you should keep in mind when you’re installing any programmable thermostat:

  • Do NOT install a thermostat on an exterior wall. If that wall is poorly insulated, your thermostat is going to think it’s either too hot or too cold. You’ll waste energy in summer and winter. Which is bad.
  • Do NOT install a thermostat where there is a steady draft. You don’t want your thermostat directly above or below a vent, since that is going to affect how it perceives interior temperature. Again, this is a recipe for wasting money.
  • Do NOT install a thermostat in direct sunlight. Ideally, you don’t want your thermostat exposed to sunlight at all. This isn’t always possible, so minimize exposure as much as possible.
  • Do NOT install a thermostat behind an obstruction like a door or bookshelf. Even though that spot might meet other thermostat installation guidelines, you’ll come to hate the inconvenience when you want to change the temperature.
  • If you’re installing a smart thermostat, make sure it is in range of your home Wi-Fi network. There’s not much point in paying for smart tech if you can’t use it.

You Can Do It

Yes, it’s possible to incorrectly install your thermostat. However, if you follow the aforementioned guidelines, you should be just fine.

  1. Please help me understand how to program the thermostat on my 18 seer split ac. I can be reached at 954 821 7333.

    Thank you

  2. I’m thinking about purchasing the Advantage 18,000 BTU 1.5 Ton Ductless Mini Split Air Conditioner and Heat Pump (Model # A-18-HP-230A) from Home Depot. Does this model have the USB port to install Wifi up grade?

  3. Would I be able to connect my DIY Enhanced 18,000 BTU 1.5 Ton Ductless Mini-Split Air Conditioner and Heat Pump – 208-230V/60Hz to a third party thermostat?

    1. The Smart Controller may allow for integration with a NEST Thermostat later this year, but at the present time the DIY is not compatible with any third party thermostats.

  4. Is the thermostat in the mr cool advantage units located in the indoor unit head or in the remote control? Also do the advantage units support the hookup of 3rd party thermostats?

  5. I have this unit… 18k BTU 16 SEER MrCool DIY Ductless Heat Pump Split System with WiFi Smart Kit – Wall Mounted. I have the temp set at 63 through the remote with the “follow me” feature. The remote thermostat is never up to 63 – typically between 59-61. Outside temps are around 20-40 degrees. The building is well insulated. The app shows a different temp than the remote. I’m at a loss.

  6. Am I able to wire in an external thermostat into the air handler bypassing the remote? I have a small indoor cannabis garden and cant risk the wifi controller. From the reviews Ive read it drops signal and the how unit has to be reset when that happens. My plants would be dead if that happened

    1. It should be technically possible to wire an external thermostat to an air handler with the right tools and training. However, it is not something we have done, and not something for which we can provide technical support.

  7. How do you install a remote thermostat for the Mr Cool DIY mini split? Is this even possible?

    I’m not wanting a wifi that just sets the temperature on the mini split, but a true remote thermostat, even if it has to be wired.
