The STTRS1 Thermostat, provides excellent automatic control of a wide range of heating and cooling applications for your home. Produced by Tower, it controls the ON/OFF function for gas valves, circulation pumps, relays and zone valves, giving you a close control of all components in your system. The thermostat is ideal for heating or cooling installations, where single or changeover switching of up to 10A for resistive or 3A for inductive is required.

The thermostat combines a great mix of design and innovative features to produce the best performance for your home. Its raised dial is a simple yet effective control method, designed to be accessible and understandable for everyone. The simplistic design encases a much more advanced diaphragm sensing element, which ensures close temperature control for all loads and applications. This allows for a control range of 10 - 30°C, adjustable in 0.5°C steps, which is suitable for most homes in the UK.

Perfect for use with combination boilers, the STTRS1 features volt free changeover output contacts and an easy to install 2-wire connection. The STTRS1 also mounts directly onto your wall or conduit box, allowing for a greater range of options for placement when installing. 

Whether you are looking for a controller for your heating or cooling system, this mechanical thermostat provides a great mix of easy to use controls and advanced temperature sensing technology. It’s easy to wire terminals and double insulated wiring means installing is quick and there is no need for an earth wire.

Suitable for both heating and cooling systems, this room thermostat is a true all-rounder. The easy to use control dial makes operation universally available and is a good solution if you have trouble reading screens.
