Smart Thermostat Buying Guide for RVs

Because these smart thermostats are not prohibitively expensive, you need to get one to add to the comfort of your RV. A good smart thermostat can be controlled remotely from your phone or computer.

Pre-programming makes the RV comfortable

Smart thermostats can easily be controlled from a remote device and can also be controlled from their device settings. Settings on these devices, unlike their analog counterparts, are more refined allowing you to set temperate changes an hour or a day before. You do not have to be near the thermostat as you can adjust the changes from your smart phone.

When you program these units, they are much more accurate than analog units. Usually, analog thermostats are off by 10 or more degrees leaving your RV to freeze or fry. When you program a smart thermostat, it is highly accurate, typically within a degree.

Does the unit control heat and air?

Most smart thermostats for RV control both heat and air. However, some cheap models will control only heat. Carefully check the device specifications before buying to ensure that it offers both hear and air conditioning control.

Again, there are digital thermostats that are not programmable but come with a horde of features and buttons to confuse buyers. Check that your unit can be programmed.

Check for Compatibility

The smart thermostat you buy needs to be compatible with your heating and air conditioning system. At times, thermostats and air conditioners from the same manufacturer may not be compatible. While substitute boards are available to make the units compatible, it is advisable to ensure the thermostat you buy will fit comfortably into your existing HVAC setup.

It is easier to find if the thermostat is compatible with your HVAC system when you are buying from a brick and mortar store. When shopping online, you need to contact the manufacturer and ask which setups the unit is compatible with. If you can get the manufacturer’s phone number, you can call them and enquire. Some online retailers also answer customer questions via live chat.

When checking compatibility, community FAQ boards might not give you the right information. Instead, call our technician (the professional who will install your thermostat) and ask them about compatibility.

Some questions to ask before buying a smart thermostat:

  • Can I mount the thermostat on the wall? When you mount the thermostat on the wall, you are more likely to get accurate readings seeing that roofs get a considerable amount of heat from the sun and heat will rise up from the ground.
  • Is the unit compatible with my HVAC system, my furnace or my heat pump? Here, you need to look for the make and model number of the unit you are buying and then conform from the manufacturer or from a professional.
  • Does the unit require you to change any control panels? If so, which control panels need to change? Smart units are mostly controlled from a mobile device over the internet. Some are controlled from a mobile app and others from the web. Check how your device is controlled before buying.
  • Does the thermostat need a wiring harness? If it needs a harness, is the harness offered with the purchase of the thermostat?
  • How do I power the thermostat? Most smart thermostats for RV are designed to run on 12V from the vehicle’s battery. However, others are designed to be fitted with batteries or run on telephone line. The unit that runs on 12V is better as you are assured it will always be on as long as your car’s battery is charged.
  • Does the unit come with backlit display? Back light ensures that you can operate your thermostat in the dark. Most units feature a digital screen with back light making them easy to operate in the dark.
  • Can I install it myself? You can install a smart thermostat with basic wiring skills. However, the problem comes when the thermostat’s warranty gets void because of DIY installation, If the warranty is not affected when you install the unit yourself, go ahead and do it.

Consider Innovative Features

Most thermostats on the market have basic features; they allow you to control heat and air conditioning systems. However, some smart units feature advanced features such as control from mobile apps and Wi-Fi compatibility. While units with more features are more expensive, they are more accurate and easier to manage.

If you only need a unit that controls your RV temperature, pick one with basic features. If you need an advanced system, pick a pricier unit with all features and modern innovations.

Consider product quality

You do not want to buy a smart thermostat that will break a week after installation. Ensure that the unit is made up of strengthened ABS plastic and not just weak plastic that breaks easily. You can also tell the quality of your smart thermostat by reading online reviews from customers.
