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

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.

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.

Have used this product in the past for rental properties. Relatively easy to fit dependant on boiler make. Pairs with base unit straight out of box.

Has lots of features which other products don't. Easy to set up once you read the manual a few times. Don't need to add any wiring it sends signals by radio. Time set up is automatic also clock's forward. We'll pleased with this product.Good value for money.

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

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.
