## Overview

The ESI Controls Electronic Dual Cylinder Thermostat offers advanced electronic temperature control with a clear LCD display and a unique weekly one-hour high-temperature boost to eliminate legionella bacteria. Designed for easy installation and precise settings between 25°C and 65°C, it balances energy savings with safety and compliance, making it an essential upgrade for modern homes.

## Description

The ESig Controls electronic dual cylinder thermostat is a revolutionary new energy saving product, developed exclusively by ESig Controls and designed for greater accuracy, more effective operation and a real homeowner safety benefit. The greatest energy and safety benefit of the ESCTDEB is the weekly one hour ‘boost’ to over 61°C, disinfecting the cylinder, killing any legionnaire disease, allowing a lower storage water temperature and satisfying a number of legal and building requirements. The hot water can be stored at any desired temperature between 25°C and 65°C, with the confidence that the weekly automatic one hour ‘boost’ to above 61°C kills any legionella bacteria, resulting in substantial energy saving. The duration of the legionella override can be adjusted from 1 to 7 days or completely disabled to operate as a conventional dual cylinder thermostat. The LCD display shows the current water temperature and the user defined water temperature, whilst the red LED indicates that the unit is calling for heat. The sensitive electronic sensors operate at a far greater accuracy than conventional oil filled mechanical thermostats, and do not need physical contact unlike traditional dual cylinder thermostats. The large dial makes it easy to set the required controller temperature (between 25°C and 65°C), whilst the second (limit) thermostat is pre-set to 80°C with a concealed manual reset, to comply with building regulations.

Review: Good but not sure - This is a great unit and exactly what I wanted. Finally a thermostat that accurately lets you set the required temperature, and also tells the tank temperature all other items on the market are guess work. Easy to install and works, however the instructions are a little unclear in regards to the 1 hour boost. I have tried everything and whist the unit works perfectly when it is turned on for the first time and the one hour boost is set on it just gets to preset temp and then turns off Not sure if unit is faulty or just the one hour boost doesn’t work if you set the desired temperature, not clear Still giving 5 stars as for the price it’s the best unit I have seen
Review: Good replacement tank thermostat - The thermostat comes with good clear instructions which makes installation easy. It requires its own mains power source and the tank needs to be pocketed in order to insert the temperature sensors. The thermostat has been installed for about six weeks now and is working very well. The big dial makes it easy to set the target temperature and the LCD shows the water temperature clearly. There is also an LED which shows when the system is demanding heat. Together, they make it easy to see whether everything is working correctly, which is helpful if you need to problem solve. Setting the temperature accurately lets you balance economy versus the hot water that you need.

## Questions & Answers

**Q: Hi all has anyone got this installed with the Hive System if so for the hive work with this**
A: Yes, it will work with Hive, however it will need its own dedicated supply as well, so if you are replacing an old 2 or 3 wire cylinder stat, you will need to run a fresh permanent live and neutral as well for it to work. Hive connection 3 goes to HW Com on the ESi cylinder stat.

**Q: Does this thermostat make a noise (click) when turning on/off? My new Cylinder has a mechanical relay thermostat which is loud and disturbs my family.**
A: A very low sound you need to be beside cylinder stat to hear it

**Q: can this be used with un-vented cylinders?**
A: It can replace any electrical cylinder stat that already controls the water temperature

**Q: how do you reset this Thermostat?**
A: The reset for the THERMOSTAT is under the adjustment DIAL. See page nine of the installation instructions.

### ⭐⭐⭐⭐ ESI - Energy Saving Innovation Controls ESCTDEB ESI Controls Electronic Dual Cylinder Thermostat, Wh
*by T***S on 11 November 2024*

- The thermostat is super easy to install, which is a huge plus. No need to call in a professional, just follow the instructions and you're good to go. - Love how it helps save on energy bills. It's efficient and does its job without any fuss, which is exactly what I was looking for. - The design is sleek and fits well with the decor. It doesn't stick out like a sore thumb, which is always a bonus. - The controls are straightforward and user-friendly. No complicated settings, just simple and effective. - The temperature accuracy is spot on. It keeps the water just right, which is perfect for those chilly mornings. **What could be better:** - The display could be a bit brighter. It's sometimes hard to read in low light, which can be a bit annoying. - Would be great if it had a Wi-Fi feature. Being able to control it remotely would add a lot of convenience. - The manual could use a bit more detail. Some parts were a bit vague, and I had to figure things out on my own.
