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conguration51
BMS burner output
• Burner is enabled subject to demand from the external
controller
• Internal appliance pump is enabled as a feed pump
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
max
(HG22) is enabled. Shutdown when TK

• 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
max
(HG22) is enabled. Shutdown when TK
max
is reached
• A low loss header or plate heat exchanger can be used to
provide system separation
