## Summary description

It provides manual temperature regulation with wired connection suitable for boilers and HVAC controllers.

## Long description

The Engo R‑S3 wired room temperature controller in black is a wall-mounted thermostat designed for direct control of heating systems. It offers manual temperature setpoint control via a wired connection, making it suitable for boilers, zone controllers and other HVAC equipment that accept a hardwired thermostat input. The compact black housing and straightforward interface are intended to fit domestic rooms and small commercial interiors where reliable, wired communication and simple operation are required.
Advantages
This wired thermostat provides precise manual temperature regulation without relying on wireless networks, ensuring stable control where radio interference or network availability is a concern. Its wall-mounted form factor and compact dimensions allow unobtrusive installation in corridors, living rooms or utility spaces. The wired connection reduces latency and improves reliability for integration with a range of heating devices that accept a standard thermostat input.
Suitable for
 Control of gas, oil or electric boilers with a wired thermostat input
 Integration with heating zones and HVAC controllers that use a hardwired room sensor
 Residential rooms, apartments and small commercial spaces requiring fixed-point temperature control
 Situations where wireless communication is inappropriate or undesirable
When it may not be suitable
The Engo R‑S3 is a manual wired thermostat and does not provide built-in Wi‑Fi, remote app control, or advanced scheduling features. If you require programmable schedules, cloud connectivity, or multi-room wireless coordination, this device may not meet those requirements. Also, it requires a compatible wired interface on the heating appliance or controller and basic electrical wiring for installation.

How to use
Install the Engo R‑S3 on a wall in a representative location away from direct sunlight, drafts and heat sources. Connect the thermostat wiring to the heating appliance or controller following the manufacturer's wiring diagram and local electrical regulations. After power and wiring are confirmed, set the desired temperature setpoint using the device controls. The thermostat will call for heating or stop calling based on the measured room temperature relative to the setpoint.
What to consider before purchase
 Ensure your boiler or HVAC controller supports a wired thermostat input and check required wiring terminals and voltage levels
 Confirm the mounting location has proper wiring access and is located away from direct heat sources or drafts for accurate measurement
 Decide if manual setpoint control without remote access or scheduling meets your needs
Usage recommendations
For stable temperature control, mount the thermostat at standing height (about 1.2–1.5 m) on an interior wall, avoid placing it above radiators or near windows, and verify wiring connections are tightened and insulated. If integration with an existing heating controller is needed, consult the heating system documentation or a qualified installer to confirm compatibility and proper wiring.
