DIN-rail controllers Controllers with adjusted hysteresis as well as the ones that cooperate with a humidity detector. Their application is very wide, starting from temperature control in apartment buildings through anti-freezing protection (gutters, pipes, valves, access roads, gates, stairs) up to industrial pipelines protection.
