Overview
The following possibilities to
configure the system are stored
in the LC1 Control. Systems 3
and 3.1 are described in detail in
this installation manual.
If you wish to use a different
hydraulic system and you do not
yet have the corresponding
documents, we kindly ask you to
request them by contacting
Strebel. If an LC-E or BSB
controller is used; see separate
controller manual.
Overview of systems 1 to 5
System 1:
Monovalent system with or
without tap water storage tank
Control of tap water temperature
Manual or automatic heating
regulation with minimum heat
consumption
Heating release
Winter or summer function
selectable by customer
System 2:
Bivalent system with or without
tap water storage tank
Control of the tap water
temperature by the lambda
control or the control of the oil or
gas boiler
Heating regulation of the oil or
gas boiler with minimum heat
consumption
Forced heat consumption before
the boiler switches to standby
Automatic continuation of
operation in the case of an
alternative operating mode
Systems 3 and 4:
Monovalent or bivalent system
with buffer storage tank and
charging valve
Dimensioning of the boiler power
according to the calculated
heating needs
Heating priority (startup relief by
means of bypassing the buffer)
Intelligent buffer storage tank
management (buffer charging
priority depends on set boiler
temperature)
Residual heat withdrawal down
to minimum boiler temperature
(differential control)
Signal to add fuel if the storage
tank temperature falls below the
minimum
System 5:
Monovalent or bivalent system
with buffer storage tank
(charging valve optional)
Constant temperature control
through controlled return
temperature of the solid fuel
boiler
Control of the return temperature
of an oil or gas-fired boiler in
bivalent systems with automatic
continuation of operation
All storage tank connection
variants
Residual heat withdrawal
through minimum boiler
temperature
Signal to add fuel if boiler burns
out (automatic continuation of
operation)
Additional function with charging
valve
Dimensioning of the boiler power
according to the calculated
heating needs
Heating priority (startup relief by
means of bypassing the buffer)
Intelligent buffer storage tank
management (buffer charging
priority depends on set boiler
temperature)
