The thermostat can control the temperature inside electrical switchboards in
conjunction with heating resistors and fans.
This thermostat can control the activation of a fan and a heater and regulate their
temperature independently.

Thermostat installation tips: the thermostat should be installed at the top of the enclosure (the hottest place). See the various operating
modes of each thermostat to choose the one that best meets your needs.
bb
Hygrostat installation tips: the hygrostat should be installed at the bottom of the enclosure. 60 % RH is the optimum value in the enclosure.
