FIELD: heating plants.

SUBSTANCE: heating plant system has central unit 1 for producing heat and providing hot primary fluid, set of local units 5 any of which has heat exchange device 13, 14 and circuit of pipelines 2, 2' drawn inside circulation system from unit 1. Any local unit intends for getting hot primary fluid through unit 13, 14 of heat exchanger. First and second local units 5 have corresponding control 27. Control unit has first aid 17, 21, 27, 29-32, 33-40, 62 and 63 for providing at least one parameter relating to need of corresponding local unit 5 in hot primary fluid. Second aid 16 performs operation of corresponding local unit 5. Second aid has at least member 25, 26 for acting on flow by hot primary fluid through local unit 5. Local unit 5 has first secondary circulation system intended for heating. Heat exchanger unit has second heat exchanger 14 for second secondary circulation system 12 for producing hot water. Control unit 27 has communication device 50 providing info transmission on mentioned parameter 17, 21, 27, 29-32, 33-40, 62, 63 from at least second local unit to first local unit 5. Control unit 27 of first local unit 5 intends for controlling operation of local unit 5 correspondingly to parameter relating to second local unit 5. There are also descriptions of local unit of heating plant system, control unit for local unit of heating plant system and method of operation of heating plant system.

EFFECT: improved efficiency of control of heating plant system.
