Hive Thermostat Mini: The best Hive thermostat If this fix doesn’t help with the blank screen problem, continue to the next step. Fix the Thermostat Display onto the Base Properly Other heating systems, apart from millivolt, proprietary, and high voltage systems, work properly with Nest thermostats. If your Nest thermostat screen remains blank after trying other fixes above, there might be a blown fuse in your HVAC system. You can ask a professional installer to fix this issue for you. The installation expert will inspect your thermostat’s wiring and HVAC system and repair any faults. Try Using Your Old Thermostat It can cleverly recognise when everybody has left the house, so you’re not heating empty rooms, as well as showing a leaf when you’re in energy-saving mode. We also like that the Thermostat E’s display switches on when you approach it and then off when you move away.If your thermostat stays blank after you’ve just set it up, you might need to re-insert the wires into the connectors. The Nest comes in a range of attractive colours and it’s easy to use: the whole outer casing acts as a dial, giving you highly tactile control over temperature, schedules and other features. You can alternatively configure everything from the smartphone app – but you shouldn’t have to do much of this as the Nest is designed to learn your preferences and create a heating schedule automatically. Geo-cache: The geo-cache is a really cool feature — we love! It will prep the house for your desired temp when you are within a certain radius A final thing to look out for is integration with the IFTTT automation service. While not exactly a must-have feature, this allows you to easily control your heating from afar or set certain events to trigger different heating modes. If your home doesn’t currently have a thermostat, you’ll probably need to engage a professional to fit your new smart device. But if you’re looking to replace an existing thermostat, you may be able to do it yourself. Choose a model such as the Tado that’s designed for self-installation and you could save a decent chunk of money. Be realistic, though: you’ll need to be competent working with electric cabling, and if you plan to fit smart TRVs then you’ll need some plumbing knowhow too. How does it connect to the network?

The Tado Smart Thermostat is a very flexible system. Assuming you already have a wired thermostat, you can switch to smart whole-home heating by simply installing the main Tado unit and the bridge that connects to your router. Later, you can add individual radiator controls to control your heat on a per-room basis. Not only do the Nest Thermostat E control and the Heat Link E thermostat look good with their minimalist designs, but they’re incredibly easy to install – Google claims that the process will take most people under an hour. This straightforwardness continues into everyday use: you can change the temperature via the intuitive app or via your chosen voice assistant. A clever Eco mode setting takes into account the thermal properties of your home so the heating isn’t on for any longer than it needs to be. There’s also an Away mode, which reduces the temperature when you’re out, and an Alexa skill that lets you control the heating in individual rooms using your voice. In all, it’s a clever system and you won’t find a multi-room heating solution for less. If you don’t want to hire an installation expert to set up your Nest thermostat for you, you can call the Google Nest support team. They’ll walk you through the installation process and ensure that you set up the thermostat properly. Closing Thoughts However, if the old thermostat works perfectly with your system, your Nest thermostat might be seriously damaged.But for Nest Thermostat E and Nest Learning Thermostat, the batteries are built-in, and they charge automatically via your HVAC system. But for some reason, your Nest thermostat might fail to charge automatically, and this may keep the thermostat screen blank. So, you’ll have to charge the thermostat with a USB cable. Tado’s isn’t the cheapest smart thermostat, but you don’t need to pay a professional to install it: it comes with detailed fitting instructions so you can do it yourself. In all, it’s the perfect system for anyone who’s just getting started with smart heating. If you suspect that the Nest thermostat isn’t working because you aren’t installing it correctly, consult an installation expert. Schedules are easily configured and controlled from the smartphone app, although you can also make adjustments from the main thermostat unit. The TRVs don’t have their own screens, but you can tweak them to temporarily raise or lower the temperature by 2ºC.

Key specs – Remote thermostat: Yes; Hot water support: Yes; Individual radiator control: Yes (optional radiator valves); Voice assistant support: Alexa, Google Assistant, Siri; IFTTT: Yes; Warranty: 1yr RTB Now return to your thermostat to see if the problem is resolved. If not, keep reading. Confirm that Thermostat is Compatible with Your Heating SystemProprietary Heating System: If your HVAC system only has 2 wires when you have both heating and cooling systems, your heating system is most likely proprietary. To help you identify whether your heating system is a high voltage, millivolt, or proprietary, we’ll try to describe them:

Millivolt Heating Systems: A millivolt heating system can be a wall-mounted or floor-mounted heater that is powered by natural gas or electricity. Even when a millivolt system uses electricity, it still provides less power than the required amount for the Nest thermostat. If you have a Nest thermostat model that uses AAA alkaline batteries, replace them with a fresh set of the same batteries. The Hive Mini is much smaller, slimmer and more stylish than the regular Hive Thermostat and yet, aside from a couple of small restrictions, it does largely the same job. We found the system performed well overall, especially in conjunction with Hive’s smart radiator valves, and was easy to use. Put the other end of the USB cable in a charger and plug it into a power outlet. Avoid using a computer to charge your Nest thermostat.A multi-room system gives you much finer control: you can set a specific temperature target for each room and even create different heating schedules for different parts of your house. There’s more to configure, though, and each radiator you want to control will need to be fitted with a smart TRV, which can easily double the price of the whole system. Does the smart thermostat require professional installation? Learning: This feature can be turned off. As far as the learning thermostats settings go, I’m happy with it. I find myself adjusting the temp less, though I nearly always want it set at a certain temp at a certain time so could easily get by with a schedule. I could see how this setting could become a nuisance if you are one to change the temp constantly at various times without some sort of pattern. For us, it took about 5-7 days before the temp was automatically changing.
