Thermocold - Innovative systems for heating and air conditioning
MULTI-MANAGER TECHNOLOGY
Multi-manager is a centralized system that allows to manage by means of a single controller, the main functions and operating modes of a group di hydronic units in modular configuration.

 

multimanager logoThanks to this device it is possible to handle up to 6 modules of equal or different capacities, even of different types and for different system configurations. It is also possible to control one or more backup units and integrated or external pump groups . The control logic developed by Thermocold is able to coordinate air/water or water/water 2-pipe systems, made by units with both screw compressors and multi-scroll compressors, both inverter and on / off.
The adjustment can be set according to the requests, in function of the inlet or outlet water temperature read by the plant probes. Communication between the Multi-Manager system and the unit is performed via RS485 serial connection. A second connection is also available for Modbus communication with third-part BMS systems.

Benefits

  • Global system control
  • High versatility
  • No stop operation
  • Maximum reliability
  • Balanced thermal loads between single modules
  • Increased global efficiency of the modular system

Compatible units:

  • Chillers and heat pumps
  • Chillers with partial or total recovery
  • Chillers with free-cooling
  • Heat pumps with 3-way valve for domestic hot water production

Compatible systems:

  • Air / water or water / water type
  • "Simple" type (units of same typology)
  • 'Mixed’ type (units of different typologies)
  • Systems with Backup Units
  • Equipped with external pump group (On-OFF or Inverter)
 

MAIN FUNCTIONS:

- Balancing of operating hours of the single units
- Balancing of operating hours between different compressors of the units
- Control, activation and balancing of operating hours of water pumps
- Breakdown of the load system by means of two possible criteria: the power balance or saturation of the units.
- Possibility to select the type of adjustment and the reference probe for adjustment (incoming or outgoing)
- Possibility to define the number of Backup Units
- Possibility to activate the steps of each unit in sequence
- Auto On/Off of the system
- Energy Saving & Dynamic Set point of the whole system
- Optimizzation of water flow according to cooling/heating capacity provided by the system
- Gradual start-up in critical conditions with a consequent limitation of absorption
- «Prevent» functions of the group of units, in case of sudden changes of the main magnitudes of the system
