Radiofrequency remote actuator with 6 channels on a DIN rail. It is designed to run air conditioning units, receiving control signals from thermostats and chronothermostats via radio frequency or wire. It has 6 relays to control up to 6 zone valves; an additional relay for the connection to the circulating pump automatically starts the circulating pump when at least one of the 6 outputs is active.
