Termostat pomieszczeniowy T22 T25 T26 IP20 PENN®

These thermostats with a sturdy steel cover are provided with a liquid filled sensing element.

This element is formed to achieve maximum sensitivity to surrounding air temperature changes. Coupled with a highly efficient diaphragm and leverage mechanism, the element operates a totally enclosed Penn switch contact with a close differential switching action without the use of “heat or cool” anticipators.
