ESI - Energy Saving Innovation Controls ESRTP4RF+ Wireless Programmable Room Thermostat, White

This is a great piece of kit at a decent price. I was sick of my wall themostat clicking on and off througout the night, i know it's weird but the sound of it just annoyed me. There are some great videos on youtube on how to install this and there are a couple of ways on how to wire it in to the boiler side. I chose to use a new 3 core from the receiver straight into the boiler PCB after disconnecting the wall thermostat connections on the PCB. Explanation below. The themostat is already paired up straight from the box but it's pretty easy to pair it up if it isn't. Its great just having the themostat in any room you want. Worcester Boch Greenstar 2000 - 3 core cable (Live, Neutral, Earth) N.B. the receiver doesn't need to be earthed so i used the Earth wire as the signal wire. Turn Boiler off before you start and remove anything wired into LR LS NS on the boiler PCB. Receiver - Live to L - Neutral to N, then put a small wire link between Live and 1, then Earth (signal wire) to number 2 (which is the switch) Boiler PCB - Live to LS - Neutral to NS and Earth (which is your signal wire) to LR. Thats it, turn boiler back on which gives the receiver power, make sure thermo and receiver is paired and away you go. You can mark the Earth wire with a permenant marker for anyone looking at it after to show it's not an Earth wire.

As a heating engineer, I always keep a few thermostats in my van and have been using ESI for a few years now. First of all, it’s budget-friendly and wireless, making it an excellent choice for installing new boilers, as ESI thermostats are programmable and compliant with Boiler Plus regulations. Secondly, they are a great replacement for any faulty wireless thermostat, thanks to their standard backplate for the receiver. The price on Amazon was also spot on, matching that of my local merchant where I usually buy other parts, but with the added convenience of doorstep delivery. Additionally, having a stand and a clear temperature display makes it even more convenient to use.

Use this for a client of mine. Initially had google nest but they keep break out of the box, so then decide to go for this product. Super easy to fit and set up. Easy to operate, signal range is good too but sometimes can lose connection, just have to reset it. So far after 1 year of using, it’s quite reliable. Had no issues. Will buy again

Installed by my electrician to the boiler. Works well and can be programmed to turn on/off at two points in the day. Can also be turned on manually. The thermostat seems to work well and can be placed in your desired position to heat the house.

Great thermostat,easy to set up,exactly what i needed

Brilliant. Easy to fit, works perfectly. Very good price

Good and easy to use. Dash board is easy to use. Once you get familiar.

Backplate doesn't have gap or knockable lug for cable entry. Backplate nuts aren't captive - a very poor design choice - so easily fall out when installing. Receiver module sits on backplate making contacts as it does so. Feels like it's going to break as it's engaged. Another very poor design choice. Display on control device has small fonts for some elements which is reasonable BUT crucially the target temperature is in the lower right and is a very small font. The actual room temperature is displayed in a nice large font. Again another very poor design choice. It does work as expected but falls significantly short in the key areas above which is a real shame as these could have easily been spotted and eliminated on the drawing board.

Recibí el articulo ayer y al abrir la caja veo que no hay instrucciones en español. Me defiendo en ingles pero veo que las instrucciones incluyen mucho tecnicismo y decido escribir al fabricante para pedir instrucciones en español. Me contestan rápidamente y escuetamente pero me dicen que no tienen, solo inglés (apáñatelas!). El anterior aparato que tenía lo instalé yo misma así que me digo que muy complicado no será... Busco en internet y veo que hay videos tutoriales, todos en ingles pero de particulares. Lo primero que constato es que en el producto que aparece en los tutoriales vienen pilas, que en mi paquete no vienen y el hueco está vacío... (sospecho). Abro el receptor que va a la caldera y veo que está manipulado, incluso sucio de cable chamuscado. Vuelvo a cerrarlo todo e inicio la devolución. Muy decepcionada.
