Electronic TRV Thermostat Valve Head (28mm to 30mm Adapter)

Product Information

When you’re shopping for a Bluetooth TV adapter, you want to make sure it can connect to your TV (or computer, if that’s your video source). Most TVs today will have a 3.5mm auxiliary output. Some come with an optical digital audio output or an RCA (stereo) output. They're like traditional true wireless earbuds, but the audio settings and listening experience can be customized with the TV Clear companion app, and the transmitter’s low latency streaming technology keeps audio and video in sync so there’s no delay in the audio. I will admit Hive TRV heads are expensive, however they do link to the wall thermostat, so in a room which without a TRV will be cool, you want the Hive as it keeps boiler running, and in a room where it would be too hot then a simply programmable TRV is good enough.

So with cheap programmable TRV heads and careful setting of the schedules you can get the same result when using timed programs. For configurations including a valve body: a thermostatic valve body should only be installed by someone competent in the installation of plumbing equipment.

Or if you want to watch TV late at night without disturbing others, you can pair a Bluetooth TV adapter with some headphones and keep the sound to yourself.

You should also think about the range: how far away will you be when you’re watching or listening? For TV watching, the range shouldn’t be much of an issue, but if you’re using the adapter to listen to music —or you’re sending audio from your phone to play over the adapter —you will likely want more range.So the Hive TRV sends a demand for heat to the wall TRV which turns it on for 1/2 hour, so with a couple of Hive TRV heads the boiler will not turn off until those rooms are satisfied not as good as Opentherm but some boilers don't have any ebus connection or it is limited as not using the industrial standard of Opentherm, so with an old Bosch boiler which does not have OpenTherm Hive is likely the best compromise.

Once you have enabled Heat On Demand, your Hive Radiator Valve will boost your thermostat automatically to turn on your heating and make heat available to your radiators when they need it.Bluetooth TV adapters come in a wide range of prices and types, with a few variations on design and abilities. Some also include receiver mode, which lets you send audio from your phone, tablet or computer; connect the adapter to a pair of wired headphones and you’ve got yourself Bluetooth headphones. The idea is Hive is a rather cheap non smart wall thermostat without Opentherm or the clever algorithms used by Nest, however by linking to the TRV heads it allows the boilers own system to modulated the boiler instead, turning off boiler means loss of energy through the flue, and the hotter the boiler is when turned off, the more energy is lost, also when the boiler is running flat out it is not running at most efficient, so you only want to turn boiler off when no longer needed, turning it off/on to regulate output means it does not run in an efficient way. It needs to be allowed to modulate (turn down) and once at minimum output the boiler needs to start cycling not wall thermostat as when the boiler does it, when it turns on again it turns on at minimum output, but if the thermostat does it then it restarts at maximum output. So idea it to let the TRV control boiler output due to return water temperature not a on/off wall thermostat. Clearly with an OpenTherm wall thermostat it does restart boiler at minimum output. Using TRV analogue control also means reduced or no hysteresis so better for occupants. The dimension across the diameter of the thread should measure 30mm and the ‘thread pitch’ should measure 1.5mm (thread pitch is the measurement of one thread to the next). The pin height when measured from the top of the valve thread should measure approximately 14mm and the radiator valve must fully close when the pin is pressed no more than 4mm (most thermostatic radiator valves will close with only 2mm of pin movement).

If you see a few drops of water when you unscrew your old radiator control then your existing valve body may be leaking. Valve bodies can often be tightened up, but some might need replacing if they are leaking. We recommend fixing your valve body before installing your Hive Radiator Valve. Get advice from a plumber if you’re unsure of how to do this.

If your existing control doesn't unscrew easily, set it to its highest temperature setting (eg “5”) and try again. Be careful to only unscrew the control and not the valve body itself. If your TV has an optical digital audio output and you don’t need the latest Bluetooth standard, the Mee Audio Connect AF-T1 could be a good match for your Bluetooth TV adapter needs. In addition to optical digital, the Connect AF-T1 also has a 3.5mm input and comes with a splitter to hook to an RCA output. At 2.2 x 2.2 x 1 inches, it’s small enough to take with you and features 12 hours of battery life. You can connect two devices at once to listen with a friend.
