Analog outputs serve for control of external devices such as three-way valves or heat exchangers through 0-10 V⎓ analog voltage signal. Devices are to be connected to **AOG** and **AO** terminals. As the output is galvanically isolated, it is necessary to source voltage for **AOG** and **AOV** (up to 35 V⎓).
