automatically identifies the consumer’s hot water
consumption patterns within a short time. It identifies
when hot water is needed and provides it proactively.
Using the button controller, the comfort setting can be
adjusted to the specific needs. LED indicators display the
current operating status of the pump.
automatically detects deviations from the “standard”
pattern, e.g. weekends, absence and daylight-savings
time.
automatically detects the time for the thermal
disinfection1.
switches the pump off as soon as the pump control
detects that hot water is available in the domestic hot
water (DHW) circuit.

Product description
The pump BWO 155 SL BlueOne is a domestic hot water
pump with a highly-efficient electronically commutated DC
motor as drive source. It is built according to the original
VORTEX spherical motor principle and contains a perma-
nent magnetic rotor. The speed of the pump BWO 155 SL is
infinitely variable.
Installation of the pump may only be performed by quali-
fied personnel.
Keep the operating instructions and other applicable docu-
ments complete, in a legible condition and permanently
accessible.
Read the operating instructions and make sure you under-
stand them before working on the pump.
This pump is suitable for drinking water only.
Only operate the pump if it is in perfect technical condition;
only use it as intended, staying aware of safety and risks,
and adhering to the instructions in this manual.
Before carrying out any installation or maintenance work,
disconnect motor from power supply and ensure it cannot
be reconnected unintentionally.

Technical specifications
In branched pipework without hydraulic balancing, the level
of convenience may be reduced.
The pump run times can be reduced to a minimum with the
BWO 155 SL. This does not contradict DVGW working paper
W 551, since the protection required against the growth of
legionellae is attained through regular thermal disinfec-
tion. This is performed automatically by the BWO 155 SL1.
Furthermore, if the consumer is absent, regular water
exchange in the pipework is ensured (daily flushing).

The drive of the pump is a DC motor. Thus a protective
conductor is not required.
For AC operation a transformer is integrated in the cap.
Electrical connection
Danger! Danger of electrocution.
►Have all electrical work carried out by
qualified electricians only.
►Turn off the power supply and safeguard it
against being switched back on (see fig. 1).
►Check to make sure the power is turned off.
Warning! Fire hazard due to electrical
ignition.
►Make sure that the pump is only connected
to the power supply specified on the name
plate.
Note: The pump deletes all commands for automatic starts
if the power supply is shut off.
►The pump requires an independent electrical power
supply. Do not connect the pump to an additional
controller or timer.
►A permanent power supply is possible, alternatively
use a mains plug with IP 44 rating (provide isolator that
separates all poles).
►Cable diameter 0.75 – 1.5 mm²
►Round cable with Ø 5 – 8 mm
►Connection with twisted wires, no wire end sleeves, no
tinned ends

Warning! Hot surface on pump housing and
motor. Danger of burns!
►Avoid direct contact with pump housing and
motor.
►Ensure that the return line is air-free (see p. 7). Then
act as follows to bleed the pump until it runs noise-free
(alternately):
►Switch the pump on and off several times (see fig. 2).
►Open a hot water tap several times (see fig. 3).
Speed adjustment
Danger! Danger of electrocution.
►Before working on the pump, disconnect
power supply and ensure that it cannot be re-
connected unintentionally (see fig. 1, p. 12).
►Check to make sure the power is turned off.

Installation conditions
The cable box must be mounted onto the supply line (hot
water pipe), independently from the type of hot water
generating system used.
Optimal distance of the cable box to the boiler: 20 to
50 cm.
If a mixer valve is present: The cable box can be installed
before or after the mixer valve.

►Secure the sensor cable with the cable ties
after laying (see figs. 6 and 14).
Installation sequence
Measure distance between pump and point of installa-
tion of cable box. Only pull as much sensor cable from
the cable box as required. The maximum length of the
sensor cable is 2.50 m. A 5m long sensor cable is avail-
able as an accessory.
The sensor cable can only be wound up or unwound
when plug A is still inside the cable box (see fig. 4).

Self-learning module
After establishing a connection to the electric power
grid, the comfort setting 3 will be set (LED 2is illumi-
nated). This comfort setting is optimal for the majority of
the applications.
►We recommend to wait three weeks before altering the
comfort settings.
►If no hot water is available immediately after opening a
tap, close tap again and wait until circulation has started.
The comfort setting is retained (non-volatile) in case of
power failure.

How does the pump learn?
A hot water tap is opened. The supply line heats up. This
is detected by the pump through the external temperature
sensor and the point in time of the hot water tap is learned.
For periodic (typical) taps the pump will proactively execute a
pump run (approx. 5 to 15 minutes prior to that point in time).
When does the pump start to run?
For reasons of comfort and independent of DHW drawings,
the pump starts frequently during the first 2 weeks (early
part of the learning phase).
Afterwards, the pump starts in the following cases:
- proactively (at the typical "learned" points in time),
- when hot water is tapped (at not yet learned points in time),
- for a flushing or disinfection cycle (see below).
The pump calculates the need for a pump run individually
every single day (Mon to Sun) based on the previous hot-
water taps of the last 2 weeks.
How long does the pump run?
The pump will run until the circulation loop is supplied with
warm water (detection through a thermostat in the pump).
The run time depends on the size of the circulation system.
How long does the pump run per day?
The daily runtime depends on the size of the circulation
system, the comfort setting and the tapping behavior of
the consumer. Typically, the pump will run between 1 and 5
hours daily.
Description of functions
How does the disinfection cycle recognition work?
The highest flow temperature measured in a given week is
interpreted as the disinfection temperature. At this point in
time, the pump will run for 30 minutes (once per week). If at
any other time of the week a higher supply temperature is
detected, the pump will shift the disinfection cycle to that
point in time.
How is absence detected (vacation detection)?
If no hot water is tapped within 24 hours, the pump will
determine an absence. Proactive pump runs will no longer
occur. A detected disinfection cycle will still be performed
(once per week). Otherwise, the pump will perform a daily
flushing cycle (duration: 15 minutes).
How will the return from the absence be recognized?
With 2 hot water tappings within an hour the previously
learned cycle will come into effect again.
How do you delete the learned tappings (reset)?
The self-learning module erases all learned switch-on
commands if the power is interrupted or the button 1is
pressed for 5 seconds.
