2-Wire termination for F5-1 — F5-4 (Wiring on accumulator)
ST9: Water shortage fuse (WMS)
ST22: Optional output 3 (WA3): Oil/Gas boiler (integrated in safety chain)
ST22: Optional output 3 (WA3): Oil/Gas boiler (not integrated in safety chain)
Water shortage fuse (WMS)
Remark: If the water shortage fuse (WMS) is enabled, the
contact opens. If there is no water shortage fuse, a wire
bridge must be mounted between KL1 and KL2.

Accumulator sensor
PF (F4)
Position F4: Upper accumulator
The order of the positioning of F5-1 to
F5-4 in the accumulator is not
important, as an average temperature
value is calculated.
The sensors F4 and F5 (1-4) have to be
positioned in 20% steps spread over
the entire accumulator height.
Sensor types: UF2000 / UFL2000
Advantage: Only 2-pin wire to the plug
board.
Terminals within the dashed lines
marked part are not used with sensor
set BSB2000.
Please note: Optional output WA3 can be loaded with a
power of Imax=5A.
If a higher power is required, a contactor or auxiliary relay
must be used.
A safety temperature limiter (STB) must be installed in
the oil/gas boiler. A boiler thermostat is not necessary
because Lambda-Control 1
plus
is EN14597 (DIN3440)
certified.
Please use only an adaptable cable with a conductor
cross-section of 0.75 mm

Please note: The option output WA3 may be loaded with
a power of Imax=5A.
If a higher power is required, a contactor or an auxiliary
relay must be used. However, KL5 cannot be connected;
i.e. only connect a bridge between KL4 and KL6.
A safety temperature limiter (STB) and a boiler
thermostat must be inserted in the oil/gas boiler.
Important note: Because of the contact protection circuit
(RC) the output is not even free of voltage when WA3
(relay contact AK-WK open) is switched off.
Please only use an adaptable cable with a cross-section of
0.75 mm
