Secure E7+ Smart Immersion Heater Timer Control Bluetooth Replacement for Horstmann Electronic 7 Economy 7 Quartz

If you have an older model, this is a great upgrade path. I bought a house that had the old analogue version, the timer was broken so I could only use it on boost and had to remember to turn on the immersion. I would often forget and then realise I had no hot water for a shower at 7am.So I got this - if you are upgrading you don't have to rewire fully. You need to isolate from the supply (turn everything off and use a volt meter to check it is off), unscrew the old box and remove the marked spade plugs. There is an adaptor plate you need to slot the new front into in order to upgrade - you don't need the back supplied in the new timer's box. Just connect in the spades as marked in the manual - the wires usually come with markers attached, slide over the cover and screw in.Once that is done, restore power to the box and the light should come on to setup. From there you can follow the manual and setup your phone to control using bluetooth.There is a wifi module add on for this that is handy - enables app control remotely.Unfortunately it doesn't connect in to any of the common voice control systems which is a pity.

Hi there,I recently purchased the E7 electronic immersion programmer and the Wi-Fi extender for my boiler. An engineer came on August 16th to install it, but unfortunately, the Wi-Fi extender couldn't connect to the router. However, the Bluetooth connection is working but slow. The engineer suspects that the Wi-Fi extender may be faulty.After contacting the support line and following their instructions, I removed the app and downloaded it again. I encountered several problems trying to log in to the new app, but Charli, the support engineer, kindly assisted me and made great efforts to resolve the issue.Unfortunately, the unit still cannot connect to the 2.4 GHz channel. I have tried several times, but it still won’t connect. Additionally, the Bluetooth connection is very slow and takes some time to establish.The main reason I purchased the unit was to have remote access, as this is a holiday home for me. I spoke with the support engineer, who advised that a replacement unit would be sent. However, when I asked who would cover the electrician's cost, he suggested that I could install it myself. I contacted my engineer, who strongly advised against this, stating that a qualified electrician is required for the replacement.Interestingly, the unit came with a security seal stating that it must not be broken, or the item may not be eligible for a refund. I’m concerned about how we can determine if the unit is functioning correctly without breaking the seal.In addition to the time spent trying to resolve this issue, there may be increased costs if the engineer needs to return to remove and reinstall the replacement unit. After searching online, I discovered that I am not the only one experiencing this problem, and I am extremely surprised that this unit was allowed to be sold on Amazon.The unit is currently disconnected from the system. I will provide all the engineer invoices and would like to return the unit and discuss who should be responsible for covering the engineer's costs.Kind regards,Ehab Ahmed

Can anyone tell me where I can buy a Wi-Fi modular for the e7
