System Configuration 52 - Wolf BWL-1S-05 Installation And Operating Instructions Manual

29.2.12 System configuration 52
External demand / control by
building management system (BMS)
DHW heating mode for system
configuration 52
BWL-1S(B)
● Split air/water heat pump
● ON/OFF activation (at input E2 / SAF)
Important information:
In these schematic diagrams, shut-off valves, air vent valves and safety equipment are not fully represented.
These should be provided for each system individually, in line with the applicable standards and regulations.
Hydraulic and electrical data can be found in the "Hydraulic System Solutions" technical guide.

System configurations
External floating contact at input E2/SAF:
Open
Closed
Notes:
- Application limits: Compressor T_FL/T_RTN = 55 °C, elec. heater T_FL = 75 °C
- The electric heater is not activated (except for frost protection and defrosting)
- C onfigure output A1 to defrost (WP003 = Defrost)
→ In defrost mode, output A1 is switched
in order to display defrost mode to the BMS.
- Ensure max. compressor starts per hour by BMS
- Ensure max. flow temperature by BMS
In this system configuration, the appliance can carry out DHW heat-up automatically
on demand. DHW heat-up mode has priority over BMS mode.
DHW heat-up mode can be suppressed in system configuration 52 by removing
the SF cylinder sensor, carrying out a parameter reset and resetting the system
configuration.
In this case, disconnect integral 3-way diverter valve for HTG/DHW.
ON - OFF
Outdoor module
→ heat pump OFF
→ compressor ON
Indoor module
A 3-way diverter valve for
central heating/DHW and
a feed/heating circuit pump
are integrated into the
indoor module
