These thermostats were developed for use on the bodies of heaters, in conditions where condensation or drops of water are likely.
The thermostat body is covered with a flexible silicone cap, allowing eventual manual reset without risk of manual contact with live parts. In order to avoid tearing of the cap by handling, it is held in place by a stainless steel flange.
The cup of the thermostat is made of stainless steel to avoid the risk of galvanic corrosion between the body of the heater and thermostat, in a humid environment. They are designed to control the liquid temperature, and their use as a dry run safety is not recommended.
When used as a safety device, when they have trigged, it is mandatory to find and repair the failure of the heating circuit before to restart.
