ESi Mechanical Room Thermostat - ESRTM Overview

The ESi mechanical thermostat is a simple-to-use room thermostat.

To control your room temperature, simply turn the mechanical control dial until your desired temperature is showing at the temperature mark.

When you turn the dial past the current temperature, you will hear an audible click. This indicates that the system is being turned ON (if calling for heat when turning the temperature up) or OFF (if not calling for heat when turning the temperature down).

Temperature and Installation

The temperature can be set between 10°C to 30°C.

The mechanical 2-wire thermostat is simple to install. It can be either surface or pattress box mounted, with an industry standard back plate, making it an ideal replacement for any 2- or 3-wire thermostat or new build.

The ESRTM is double insulated and also has volt-free contacts, making it suitable for systems with either a combination or normal boiler.

If you have a 3-wire installation, simply cut back and make safe the neutral, and this mechanical thermostat will provide you years of service.

Choosing the most suitable kind of Heating Control is a major decision. When you decide that Room Thermostats are the right answer then the ESi Controls ESRTM is without doubt worth your consideration.
