The Sequencer is a centralised management and control system for a group of hydronic chiller units, and heat pumps. It can control up to 5 units, with similar or different capacities, in 2 pipe. Regulation may be set according to the temperature read by the system return probe. It is supplied in an industrial box complete with all components. The sequencer dialogues with the units via a RS485 serial connection. It has its own adjustment probes to be placed in suitably prepared pockets in the hydraulic system pipes.
