Modular Configuration Units - Bosch CS 3000 AWP Installations- Und Bedienungsanleitung

Modular configuration units

Prior to removing the protective grill or the fans, open the isolator on the
attachment line of the unit itself, padlock it and display the appropriate
warning sign.
Refrigerant
The intervention of the safety valve and the consequent eject of the gas
refrigerant may cause injuries and intoxication.
Should the refrigerant leak please refer to the refrigerant "Safety sheet".
Contact between open flames or heat sources with the refrigerant or the
heating of the gas circuit under pressure (e.g. during welding
operations) may cause explosions or fires.
Do not place any heat and ignition source next to the refrigerant.
The maintenance or repair interventions which include welding must be
carried out with the system off.
Hydraulic parts
Defects in tubing, the attachments or the removal parts may cause a leak
or water projection with the consequent damages to people, things or
short-circuit the unit.

14 Modular configuration units
This feature allows up to 16 units to be connected.
The system is completely controlled by the Master unit. Each connected
module is identified by an address, from 0 to 15: the Master unit is
identified as 0.
The TW leaving water temperature control probe, the flow switch and the
auxiliary electric heater must be controlled by the master unit.
All units must be electrically connected to each other via the X-Y-E BUS.
Each module can be equipped with an inertial system storage tank.
Each unit with DHW option must have its own DHW storage.
An external pumping unit sized for the entire capacity of the modular
system must be provided (by the Customer). The pumping unit will be
managed by the Master unit through a potential-free contact and 0-10V
signal.
The TW probe of the master unit must be reinstalled on the common
supply line from all units, as far away as possible.
