Immediately below the level of the transparent window, the warm air flow it generates prevents from condensation on the window and keeps an optimum ambient temperature for the control devices in the housing. It has a wide aluminum heat exchanger to reduce its surface temperature and a miniature snap-action thermostat limits the temperature inside the cabinet.
Mounting with 4 screws under the lid, connection in parallel on the power supply, directly on the terminal block. Its operation can be permanent, as soon as the cabinet is powered up, or controlled by the cabinet power lighted switch. It can be coupled to a room thermostat built into the case, triggering its start when the outside ambient temperature drops below 4°C +/3°C and cut back when above 10°C +/-3.
