A5-20-01

The EEP "A5-20-01" specifies a heating readiator valve drive. We recommend using it with an external PID controller (e. g. the heating controller node in Node-BLUE). You should also note the "SERVICE_COMMAND" "SummerMode" which should always be set in summer to reduce energy consumption. It makes the actuator send packets and accept new input every few hours instead of every few minutes.
