The Room Thermostat II and Room Thermostat II 230 V are also convincing thanks to their modern LED display, which clearly and legibly displays all information relevant to room-temperature control. Intuitive operation by turning and pushing the button of the Room Thermostat II and Room Thermostat II 230 V is now additionally supported by visual signals from a multicoloured LED strip. For example, red LEDs indicate that the temperature is being increased, while blue LEDs show that the temperature is being lowered. By default, the system is set to do this immediately, but you can change the delay to between zero and 180-seconds. Normally, I’d argue that implementing this feature in software is better, with the thermostats measuring the temperature drop to detect when there’s a window or door open. However, Bosch’s Door/Window sensors can also be used in the alarm, setting off a siren when the alarm is armed.

Many homes already have thermostatic radiator valves (or TRVs for short) on their radiators. They work by detecting the temperature of the room, and turn the radiator on or off depending on whether the room needs heating up or not. Regardless of which you choose, they’re easy to use once installed, especially since you control them using a smartphone app or, in some instances, voice commands if you also own one of the best smart speakers. This is the set up a lot of homes will have. You can manually set the thermostat temperature, and it will turn the boiler on and off to maintain the temperature of the room it's placed in. It builds on the Nest Thermostat E's white plastic design by being available in four different colored trims, which complement the screen's shade. However, as it's relatively smaller than most non-smart thermostats, you'll likely need an additional trim plate to cover up the holes when installing this model. Sadly it doesn't come with a stand as the Nest Learning Thermostat does, so it can only be wall-mounted.

Further Features

If you don’t have an on/off appliance and it takes a minute before the adapter lights up green, the Bosch EasyControl Adapter has automated opted for on/off signal although it is not right. The function of a smart radiator valve (or SRV for short) is exactly the same, but with these four key advantages: Comfortable climate at the touch of a finger: Thanks to the Radiator thermostat with targeted temperature control for individual rooms and intelligent timer, you can easily determine the heat output in your home. EasyControl is compatible with Bosch ETRV's, which allow precise temperature control for each room via the EasyControl Smart Radiator Thermostats.

If you have a regular schedule, you may well benefit from being able to program a heating schedule. Your device lights up blue and red to show you the start and end of the heating break during ventilation. Smart TRVs are smart thermostatic radiator valves, which, in combination with the EasyControl, allow you to control the heating in each individual room to give maximum comfort when and where you want it. Two additional adapters (Danfoss RA and Danfoss RAVL) are included in the scope of delivery; further adapters (M28 and Danfoss RAV) are available as accessories in the online shopOnce created, a schedule can be copied to different days but not rooms, which is a bit of a pain if you have a lot of Radiator Thermostats in different rooms. A84-1876: The connection to the appliance has been lost. No communication to the appliance is possible. Efficient heating: heats precisely as needed and with energy efficiency thanks to time programmes and special services such as “Sustainable Ventilation”. Bosch can see if your product is online but cannot gain access to your information. If necessary, you can authorise Bosch to gain temporary access to your product. The temporary access can be revoked at any time by turning it off in the app. All the smart radiator valves can communicate with the smart thermostat, meaning you can turn the boiler on and off by changing the settings of any of the heating devices. Out of our three home setups, this gives you the most complete control of your heating.

There’s also a scheduled mode. Again, this too is basic. You can set a “Warm phase” and “Cold phase” temperature, and then the schedule lets you choose which periods use each phase. Thanks to its compact size (87 x 51 x 51 mm (LxWxD)) and swivelling display, it fits discreetly into your living room – either horizontally or vertically mounted. Having TRVs installed on your radiators allows you to set the temperature in individual rooms. This makes it easier for you to keep rooms at a consistent and comfortable temperature and save on heating bills by only heating the rooms you need to. Smart thermostats connect to your home Wi-Fi network and ensure an app on your smartphone, or you can use a voice assistant to switch your home’s heating and cooling system, even if you’re not at home. As well as adjusting the temperature in your home, most smart thermostats also enable you to set schedules, provide a report charting your energy use and even stop your heating coming on at all because, for example, you’re heading out of town. Like most home smart home gadgets, smart thermostats can also be used in home automation that uses other smart home gadgets, such as smart lights and smart plugs, all controlled simultaneously. So you can turn the heating up, dim the light and watch your favorite TV show with one command. What are the disadvantages of a smart thermostat?I started with the Indoor Climate Starter Kit, which gets you the Smart Home Controller (the hub), two Radiator Thermostats and a Door/Window sensor, which lets the heating in a room turn off when you have a door or window open. The control panel and radiator thermostats aren't going to win any design awards, coming as they do in plain white plastic, but that's not really the point of the Evohome. It's expensive, too - as you'll need a smart valve for each radiator in your home. However, it's worth it for the granular control you get over your heating. Simply set your desired temperature via the Smart TRV or the EasyControl app and an integrated sensor will continuously monitor the room temperature to keep it at your desired level. Several time-controlled settings are possible per day, and you can also set different times for every day of the week. Before selecting the right smart thermostat for you, there are some aspects to consider.As we’ve already mentioned, there are two types of smart thermostats to consider. Smart thermostats that control your system as a whole are usually more affordable and easier to install than smart thermostats that offer zonal control. However, you may find you’re still heating or cooling rooms that you’re not using and subsequently wasting energy and money. There’s no Google Assistant skill available at the moment, so you can’t use your Google Home system. There’s currently no IFTTT channel for the Bosch system. Why buy the Bosch Smart Home Heating and Radiator Thermostat?

However, smart thermostats can make life easier as well as potentially put an end to wasting energy. For example, if you're going to be late home from work, you can switch the heating or air conditioning off remotely, so it's running full blast in an empty house. Similarly, suppose you've been away on holiday. In that case, a smart thermostat can ensure your home is at a cozy temperature as soon as you walk through the door, rather than waiting hours for the property to warm up as the HVAC system has been switched off for a week or two. Limescale protection: To prevent limescale from forming in your thermostats outside the heating period, the valve opens briefly once a week throughout the year.

Do it the Easy Way

Simple wall mounting by means of enclosed screws and adhesives. No wiring is necessary because four AAA batteries power the unit. Battery lifetime: up to two years. Full overview: the current temperature and relative humidity in the room, as well as the status of the heating controller, are shown at a glance. A84-1870: A low battery has been detected on one of the linked wireless devices. Battery replacement is required. The radiator valves are big chunks of plastic that replace your existing valves. Bosch provides adapters in the box for multiple fittings; I had no problem fitting them to my radiators.
