Ограничитель температуры обратного потока Thera-RTL (T6102)

Thermal return flow limiter Thera-RTL (T6102)

Thera-RTL (T6102) is a thermostat with an internal element designed for limiting the return flow temperature of radiators. This solution helps stabilize the hydraulic regime of the heating system, reduce overheating, and maintain the specified operating parameters. Thanks to a successful design, it provides good readability of the setpoint from any angle.

The thermostat performs two key functions: limiting (restricting) the setpoint range and locking the selected value — this setting is implemented without the use of tools.

How it works and what it's suitable for

The device limits the return flow temperature:

• for radiators — the return water temperature in the radiator circuit is limited to the specified setpoint range;
• for combined radiator/warm floor systems — the device can limit the return flow in the warm floor loops;
• the limiter ensures the stability of the heating system's operation and helps meet temperature requirements.

Key advantages

• Excellent readability of the set temperature from any angle.
• Hidden limit and lock tabs — controls are not conspicuous and help protect the setpoint from accidental changes.
• Setpoint range 20–50 °C at nominal flow.
• Functions of limiting and blocking the setpoint — for mode control without unnecessary actions.
• Compatibility: used only with standard Honeywell Home radiator valves types BB and KV.

Important when purchasing: how to buy from an official dealer

For correct selection, warranty, and support, it is recommended to purchase equipment Resideo (Honeywell) from official dealer — LLC "Promelektronika". You can contact via email: sales@prom-elec.com.

It is also important to note that Resideo (Honeywell) equipment is still supplied in full volume to Russia, so if needed, you can plan purchases and system configurations.

What can be configured with T6102

• Selection of the set temperature in the range 20–50 °C.
• Limiting and blocking the setpoint range to maintain stable operation.
• Control of the return flow temperature in radiator/mixed systems.

If you are selecting a component for controlling the return water temperature, T6102 Return temperature limiter will be a reliable element of the system and will allow maintaining the specified operating mode of the heating circuits.
