Room thermostat SALUS RT20 analog electronic 412200 — wired temperature control for heating systems

SALUS RT20 analog electronic room thermostat (model 412200) is a wired temperature controller designed for straightforward manual regulation of indoor heating systems. The unit provides a clear user interface with a rotary setpoint control and simple indicator elements, enabling stable temperature maintenance for boilers, radiators and electric heaters in residential or light-commercial environments. The RT20 is intended as a replacement or upgrade for basic room control, offering reliable on/off switching of heating circuits to support comfort and energy-efficient operation.

Advantages

The SALUS RT20 delivers precise manual temperature setting with minimal complexity, making it suitable for users who prefer tactile controls rather than programmable interfaces. Its analog electronic design ensures stable regulation and reduces temperature oscillation compared with purely mechanical thermostats. As a wired thermostat, it provides a direct and reliable connection to heating equipment with simple installation and integration into existing control wiring.

Suitable for

• Wired control of domestic boiler heating circuits
• Room temperature control for radiators and convectors
• On/off control of electric heaters in individual rooms
• Replacement of basic thermostats in apartments, houses or small offices

Key specifications

• Control type: analog electronic temperature control with manual setpoint adjustment
• Interface: rotary setpoint control and status indicators
• Connection: wired hardwired electrical connection for switching heating circuits
• Switching output: on/off control suitable for boilers, electric heaters and zone valves
• Mounting: wall-mounted room thermostat form factor
• Application environment: indoor residential and light-commercial spaces

How to use

Mount the thermostat on an interior wall away from direct sunlight, drafts, doors and heat sources to ensure accurate room temperature sensing. Connect the thermostat wiring to the heating system following the system wiring diagram and local electrical regulations; the device provides a wired switching output to control a boiler, electric heater or zone valve. Set the desired room temperature by rotating the setpoint control; the thermostat will switch the heating on or off to maintain the selected temperature. For safety and reliable operation, have electrical connections performed or checked by a qualified technician if you are not experienced with heating controls.

Usage recommendations

Position the thermostat at typical room height (about 1.5 m) in a representative location to achieve consistent temperature control. Avoid mounting near heat-emitting appliances or external walls with strong drafts. Regularly check wiring connections after installation and consider pairing the RT20 with properly sized actuators or valves for optimal system response and energy efficiency.
