The regulator allows independent control of two circuits of frost protection. Thanks to that heating of pavement and roof gutter/pipes or frost protection of northern and southern parts of the roof can be controlled concurrently by one regulator. The regulator allows even two-grade control of performance or control of hot water systems of frost protection. Both circuits must have its own humidity sensors (ETOR-55 for roof and ETOG-55 for ground applications), temperature sensor ETF-744/99 (it is shared for both zones) must be connected in roof gutter protection, humidity-temperature sensor ETOG-55 senses temperature for ground applications, or, as well as in roof protection, shared temperature sensor ETF-744/99 can be used. Temperature sensor is placed into the "coldest" point of application (northern side of the building or non-sunward point).

Sensors are not a part of the regulator, they are ordered according to the type of application (communication and/or roof protection) and according to the number of protected zones. Regulator ETO2-4550 is placed into the switchboard onto DIN rail (9 modules).
