from 2 V
• No temperature control
• Input E2:
0-10 V control from the external controller
0-2 V burner OFF
2-10 V burner output min. to max. within the programmed
limits (HG02 and HG04)
• Automatic output reduction when approaching TK
(HG22) is enabled. Shutdown when TK
System configuration 52
BMS set boiler water temperature
• Burner is started subject to demand from the boiler
thermostat
• Internal appliance pump is enabled as a feed pump from
2 V
• Boiler thermostat
• Input E2:
0-10 V control from the external controller
0-2 V burner OFF
2-10 V set boiler water temperature TK
(HG22)
• Max. set boiler water temperature = TK
(hysteresis)
System configuration 60
Cascade (automatic setting if cascade module is
connected)
• Burner starts following a demand from the cascade
module via eBUS (0-100 % burner output; min. to max.
within the programmed limits HG02 and HG04)
• Internal appliance pump is enabled as a feed pump
• Header temperature control via cascade module
• Input E2: not assigned
• Automatic output reduction when approaching TK
(HG22) is enabled. Shutdown when TK
• A low loss header or plate heat exchanger can be used to
provide hydraulic separation.
Important information:
In these schematic diagrams, shut-off valves, air vent valves and safety equipment are not fully shown. These
should be provided for each system individually, in line with the applicable standards and regulations.
