1. General information
Bartec KRM thermostat is a 16 A switching capacity mechanical change-over controller housed in a polyester enclosure. Heaters, fans, motors and other equipment are energized and de-energized when temperatures fall below or rise above certain limits. It can also be used to control the temperature in air, liquids and on various surfaces. Its capillary tube length of 1600 mm gives installation flexibility. KRM Capillary tube thermostat with a compact enclosure and double units are standard. The weather-proof capillary tube thermostat, Any change in temperature at the sensor bulb causes a change in the volume of fluid in the measuring system, which in turn results in a movement of the diaphragm membrane. This membrane is connected to a mechanical device that activates a micro switch. If the temperature at the sensor bulb exceeds the pre-set value, terminals 1 and 2 are opened. If the temperature falls below the minimum setting, the contacts automatically close.
