I have a Drayton TRV4 thermostatic valve on the radiator. Is it correct that it can be installed on both the Flow or Return and can be mounted either horizontal or vertical? What I always mention reviewing this item is to get any kind of accuracy with this set up (which is vital in my circumstances of course) you need one of these stats for every room, I bought the system believing the radiator valves were sufficient and only one stat was needed for “the most important/main room” my finding was despite the valves apparently being adjusted to allow for being close to the radiators when sensing the room’s temperature it just didn’t work, you got a sort of boom/bust situation. The heating would run, the area by the rad was of course much warmer than the room the valve shut the radiator believing the space was at temperature and it could be 8 degrees off..eventually the radiator would cool, the valve would realise the room was freezing..it would run the boiler/open and so on, essentially the room was never sufficiently warm. I think this is a common criticism of thermostatic valves, I’ve never bothered with them until now/my engineer doesn’t like them. Trv’s might be different in a modern/efficient house -can’t say, maybe try it out? I used my old stats display/with it disconnected as a room thermometer(it’s battery powered) to tell me what was happening in statless areas. I have a Digistat RF and I have managed to snap one of the clips on the battery holder. Where can I obtain a replacement The actuator head of a ACL Lifestyle 2-port motorised valve (679H308-30L1) has failed. Is it still possible to get the actuator for this valve to avoid draining the whole system?

Anyway, I got a smart central heating system right at the start of this whole energy crisis/cost of living nightmare, I can’t get a heat pump(!) likely my building is too old and energy inefficient to work with this anyway smart heating seemed like something doable/affordableManual thermosta:This option has no schedule and controls by temperature only. You set your preferred temperature and adjust it with the + and - buttons. However, it does have an Away Mode. Rather than switching the heating off completely while you’re out, this feature allows you to set a minimum temperature at which you want your home to remain at while away. If the temperature plunges below this threshold, the heating will spring to life – handy, if you're concerned about frozen pipes when you’re not at home. The unit is simple to mount on the wall or there’s a stand, the batteries are easy to fit and it’s easy to add to the system like the other devices. The Digistat qualifies as one of the additional measures required when replacing a boiler. In fact it qualifies both as a Smart Control and as Load Compensation.

Yes, there is a Digistat to suit both types of boiler – try our product selector to find the right one for you. The Insights tab includes information on how much energy you’ve saved with Eco mode enabled, while also presenting a ‘Heat Report’ that details how long and to what temperature over the past day, week, and month your rooms have been heated.From the home screen, you can also view the weather for your location and sunrise and sunset times, too. The cog icon at the top of the home screen provides access to the main Settings menu, from where you can activate smart modes such as Eco and Comfort, and set a temperature for the Away mode.

We did notice a slight delay of around 10 seconds to one minute between boosting the heating from both the radiator thermostat or the app and the boiler springing into action. The further away from the Heat Hub the thermostat is, the longer the delay. Initially, we also struggled to get the radiator thermostat in the room furthest from the Heat Hub to remain connected to the system at all times. It would often drop the signal, meaning we were unable to control it via the app. However, after installing an optional Wiser Smart Plug – which also doubles as a range extender for the system – in a room between the Heat Hub and the troublesome radiator thermostat, connection issues were no longer a problem. The final component, the smart radiator thermostat, is a white plastic cylinder, which fit to the radiator once the existing valve has been unscrewed. To manually override any schedules you may have set, simply swivel the top of the radiator thermostat right to start the radiator heating, or left to stop heating. An LED on the radiator thermostat glows red temporarily when the radiator is heating, and blue if it's been turned off. Turning and holding the radiator thermostat will also reset or put it into set-up mode, depending upon how long you hold it in that position. We also found it was easy to create some basic automations in the app using the Moments feature - such as turning the radiators in the lounge on, while also dimming the map connected to the Wiser smart plug to create a cozy atmosphere of an evening. AppI’m not sure about rating this as “amazing” (5 stars) but “better than expected” (4) didn’t seem a fit either..it’s a central heating thermostat..can’t we just give a star rating without these associated comments?? No, E1 is an error code that means the internal sensor has failed. The sender unit will have to be replaced. Drayton Wiser may be functional, but its plain all-white plastic design certainly isn’t stylish. If you prefer gadgets that make a design statement, this isn’t the smart thermostat for you. The Digistat remembers the last BOOST so if you always use the same parameters just press the O button 3 times. Simple! You can tap on a room and edit the schedule or access the room settings, where you can view the battery level for the thermostat, rename it and turn Open Window Detection on or off. Editing a schedule was made super-easy as a result of the ‘copy’ feature, which lets you duplicate a schedule with just one tap, rather than having to input it all for each day and on each device.
