Capillary tube/boiler thermostat with immersion sleeve

By means of a pipe sleeve immersed into the pipeline/boiler, the probe located at the end of the capillary tube of the thermostat directly detects the temperature of the material stagnating or flowing in the pipe/boiler and, in response to a temperature change, it provides a potential-free electrical closing/opening contact at the adjusted temperature.
We primarily recommend using it to control pumps for underfloor heating and hot water circulation.
