ESi Electronic Dual Cylinder Thermostat Overview

This electronic cylinder thermostat allows you to store water between 25°C and 65°C with the confidence of a weekly automatic one-hour 'boost' at 60°C that kills any legionella bacteria.

LCD Display

The LCD display shows the water's current temperature and your defined water temperature, and the red LED indicates that the unit is activating water heating.

The large dial makes it easy to set your preferred temperature, whilst the second (limit) thermostat is preset to 80°C with a concealed manual reset to comply with building regulation.
