Contour offers four different thermostatic radiator valve (TRV) kits specifically designed for our LST radiators. They are available for both two pipe and one pipe systems.

Read on to find out what’s included in the kits…

9210-13 Standard Internal TRV Kits

This TRV system is suitable for areas where access to the valve is not of a high priority and can be adjusted once a year.

The standard internal TRV kit must only be used in Bottom Bottom Opposite End (BBOE) connections to avoid the thermostatic head from getting false temperature readings.

7463-41 Internal TRV Kit With Remote Sensor

This is suitable for spaces where it doesn’t need regular adjustments. However, the radiator is connected TBOE, meaning the thermostat will be located at the top of casings.

This means that you would locate the remote sensor at the bottom inlet grill. Suited to TBOE connections, you will be able to read the correct temperature.
