## Description

Product Description The ESi Controls ESCTS Cylinder Thermostat is configured specifically for the control of the domestic hot water cylinder to suit householder lifestyles and is suitable for both un-insulated and foam lagged cylinders. The ESCTS can be used to switch directly a wet central heating circulating pump or boiler, or to operate zone valves. The bimetallic sensor ensures accurate hot water temperature control, whilst the large clear adjustable dial is easy to read and adjustable between 0C and 80C. The ESCTS can provide energy savings when set between the recommended 60C and 65C. The Cylinder Thermostat is very easy to fit and is designed for surface mounting on domestic hot water cylinders or tanks. The ESCTS can also be mounted on the pipe, and comes supplied complete with both an extra-long mounting strap (and hooks) for the even the largest cylinders and a spring for the heating pipes. Box Contains 1 x Hot Water Cylinder Thermostat

Review: Works well - Bought to replace an ancient one that seemed to want the tank far too hot even on minimum setting. This was easy to install and now my water is a better temperature (and I should be burning less oil). No idea as to the accuracy, but it does what I need.
Review: Ideal item - The item was easy to install and easy to set to required temperature . Super Quick delivery .

## Questions & Answers

**Q: What is the hexagonal part in the middle of the body that has a hole in the middle for?**
A: I holds the cylinder stat together. You need to undo this rand remove the front to wire it

**Q: Can it be fitted in a bathroom on pipe work**
A: This is a thermostat for an immersion tank so, NO.

**Q: Your text says it is suitable for foam lagged tanks but how does it measure the temperature?**
A: You would have a hole in the lagging just big enough to fit the unit and the sensor on the back of the thermostat would measure the temperature.

**Q: Is the thermostat a simple on/off switch for a wired connection?  The description says it has WiFi connectivity.**
A: Yes
