Appliance overview
Features and safety devices
Easy to operate and environmentally friendly
The heat pump has user interface with easy use menu keys for
programming. The heat pump is also environmentally friendly
as it transfers heat from the surrounding area into the water.
Heating capacity
The unit absorbs ambient energy and releases the heat into the
water stored in the tank. If the ambient temperature is low, the
heating capacity of the heat pump will be reduced, but you can
still rely on the electric element for backup: the electrical
element will automatically turn on below 0 °C to assist the heat
pump module.
6 720 808 869 (2017/06)
Thermal Cut Out (TCOs)
The water heater is equipped with one thermal cut-out (TCO)
located near the heating element. If for any reason the water
temperature becomes excessively high, the thermal cut-out
(TCO) cuts the power circuit to the heating element. Once
activated, the TCO must be reset manually. Resetting of the
temperature limiting control must be done by a qualified
service technician.
CAUTION:
The cause of the high temperature condition
must be investigated by a qualified service
technician and corrective actions must be
taken before placing the water heater in
service again.
Compress 3000 DW FOO
Appliance details | 9
Defrosting
During the heating, when the air temperature is between -7 °C
and 10 °C frost may be formed at the evaporator, thus blocking
the air flow and reducing the heat transfer efficiency.
To avoid this occuring, the appliance will automatically defrost
the evaporator by injecting hot refrigerant gas into the
evaporator circuit via a bypass valve. The control of this
functionality relies on the temperature readings of the air and
fins sensors.
The defrost cycles last typically between 5 and 15 minutes and
their frequency depends on the environmental conditions (air
temperature and relative humidity).
During the defrost cycles only the compressor runs. After the
evaporator defrost is concluded the unit returns to normal
operation.
In case the air flow is restraint, for instance due to high wind
intensity at the air outlet, the frequency of defrost cycles might
increase.
Working condition
The appliance is designed to operate with best efficiency when
the air temperature is between -7 °C and +40 °C.
Care should be taken to feed the unit only with potable water
( section 4.9.1). Do not use untreated water from lakes,
rivers or groundwater!
Overheating protection
In case the water temperature near the electrical heating
element reaches 84 4 °C the power to the electrical element
is cut off by a thermostat mounted together with the electrical
heater and will require a manual reset.
Water temperature and pressure protection
The unit is supplied with a PTR valve for your safety (supplied
accessory). If the tank pressure reaches 1000kPa or the
temperature reaches 99 °C, the PTR valve will open
automatically to allow the pressure or temperature to decrease
to safe values.
The warranty can become void if relief valves or other safety
devices are tampered with or if the installation is not in
accordance with the instructions in this manual.
Mains Pressure
This water heater is designed for direct connection to mains
water supply. In case the mains supply pressure exceeds
800kPa, a pressure limiting valve must be installed
(section 4.4.4). A minimum water supply pressure of
200kPa is required to assure the effective operation of this
water heater.

System basic theory
The refrigerant circuit is a closed system in which the
refrigerant R134a circulates as a heat transfer medium.
The evaporator transfers the heat from the air to the refrigerant
circuit, and the refrigerant evaporates into a gas.
The compressor compresses the refrigerant R134a, thus
increasing its temperature.
Then, the heat is transferred via a heat exchanger, also referred
to as a condenser, to the storage water tank. The refrigerant
R134a condenses in the process.
R134a flows through the expansion valve in a liquid state with
decreasing pressure, thus completing the cycle by being
routed back to the evaporator.
Brief overview of the appliance operation
Between 0 °C and 40 °C air temperature the appliance only
uses the economical heat pump cycle.
However, it is possible to manually turn on the electrical heater
together with the heat pump when the air is above 0 °C (One
shot boost). Once the set point is reached the boost is
automatically switched off.
Between -7 °C and 0 °C the appliance automatically switches
on the electrical heater together with heat pump cycle.
When the appliance has conditions to activate both electric and
compressor "FULL" is displayed at the HMI, alternating with the
top tank temperature.
When compressor and electrical heater are operating together,
the upper part of the tank will rise much faster than the lower
part, thus boosting the recovering time for the next hot water
load. Hence, with "FULL" active, if the top temperature gets
near the set point and the bottom is still rather at low
temperature, the appliance, will automatically switch off the
electrical heater and continues the heating with the heat pump
cycle only but "FULL" will remain being displayed.
After the electrical heater is switched off, it is normal that the
top temperature start to decrease slowly. Therefore, while
rising the bottom temperature by only using the heat pump
cycle and until the top temperature start to increase to set
point, the electrical heater will be switched on as many times as
required to keep the top near the set point.
Outside the air ambient range temperature, the unit operates
by only using the electrical heater.

4.9.1 Water characteristics
Usage of water with unsuitable characteristics can result in
shortened product life.
Water treatment vs water characteristics
Please note that the Langelier saturation Index depends on the
water temperature and the above information considers two
extremes: 10 °C and 70 °C.
While corrosion is higher at low water temperature, scaling is
more important at higher water temperature.
In case of water hardness above 600 mg/l, the Langelier
saturation index must be determined to evaluate the necessity
for water treatment.
Please require help from your technical assistance.
To ensure that the sacrificial anode works properly, the water
conductivity must be within the limits of Tab. 4. In case not,
treatment is required. Always ensure the water characteristics
described in Fig. 18 when applying water treatment targeting
the water conductivity

4.11 What to expect from a “normal startup”
After the unit has been installed, with all electrical and water
connections secured and checked, the unit should be filled
with water and purged ( section 4.9). The appliance will
perform according to table 5 after purge function has been
selected. In case the appliance is unplugged from mains and
switched on again, the display will remain inactive for a few
moments and the normal startup will be according to table 6.

If the ambient temperature is outside of the
range -7 °C / +40 °C, the appliance will not be
able to run by using the heat pump cycle. The
electric element will be used until the
ambient air temperature returns to the
operating range, therefore, the unit will not
follow the startup described in tables 5
and 6.
4.12 Off-peak compatibility
The appliance is technically compatible to be connected to a fix
line for off-peak tariff. However, the off-peak must be wisely
used.
Off-peak periods of less than 16 hours might not ensure the reheating, depending on the hot water demand and on the
temperature of the air and inlet water. Ensure that your offpeak periods are suitable for your needs.
to complete the thermal disinfection. It is recommended to
program the LEG to be done when extended off-peak periods
are available, typically weekends.
To optimize the comfort and maximize the savings, it is
recommended the use of a power commutator between the
normal line and the off peak line together with a programmed
working period (section 5.7.2). The best strategy will
depend up on the hot water needs and ambient conditions.
In case time of use tariffs are available, it is recommended to
use the programmed working periods (section 5.7.2) to
take full advantage of them.
In case of a temporary suspension on the water supply during a
off-peak period the appliance may get unpurged and stop
working during its restart. An error message will be displayed
and the appliance will remain blocked. To minimize the
possible inconveniences from a suppression on the water
supply service, always check the appliance after such incident
occurred.
NOTICE: Damage to the appliance!
Never use the off-peak in case the appliance
is set to OFF mode and temperatures around
0 °C or below are expected: the anti-freeze
mechanism will not be ensure!
4.13 Demand response
In a near future electrical energy management is foreseen to
use communication with the electrical appliances to minimize
grid load peaks and increase electrical energy distribution
efficiency. This communication, named demand response, will
be based in signals sent through the grid to which the electrical
appliances are required to react accordingly. The end user is
expected to benefit from lower tariffs when using appliances
demand response capable.
The Compress 3000 is technically demand response ready.
The Compress 3000 is technically prepared to what is
expected to be known as Demand Response Modes 1 and 4
(DRM1 and DRM4). Under DRM1 the appliance is
automatically switched ON or OFF according to the grid signal.
Under DRM4 the appliance will automatically increase the set
point to 66 °C (10% higher than the highest set point possible
to be set) when the respective signal is sent through the grid.
The interface between the grid and the appliance requires a
Demand Response Enabling Device (DRED) and a BOSCH
accessory. The availability of this feature and accessories
requires regulation approval and release by the government
authorities.
The weekly LEG mode requires additionally 6 to 8 hours.
Therefore once a week this additional period must be ensured

Appliance status information | 35
In case a programed period (P1, P2 or P3) is
selected, the auto-activation of the LEG
mode will be postponed to the next
activation of the selected programed period.
The finalization of the thermal disinfection
will have priority over the end of the
programed period,i.e., in case the
programed period is too short to allow the
conclusion of the LEG mode, the appliance
will be forced to operate until the thermal
disinfection is concluded.
Manual activation of the „Leg“ function
▶ Access the „Leg“ function and press „ok“.
▶ Select "
" by using "+" and "-" keys.
▶ Press „ok“.
„Leg“ function activated.
Upon reaching a temperature of 60 °C at the bottom part of the
tank for more than 35 minutes, the device returns to the
previously selected mode.
The disinfection cycle manually activated will
not inhibit the automatically scheduled
disinfection cycle.
The legionella disinfection may take
additional 6 to 8 hours to be conclude after
the regular heating assured by the heat pump
cycle. To draw off hot water from the tank
during the last stage of the legionella
disinfection may extend the process. In case
24 hours have passed since the legionella
process has been activated, the appliance
will turn on the auto-boost to speed it up.
Therefore, to maximize the appliance
efficiency, it is recommended to always
program the legionella to a period where no
hot water consumption is expected for a
longer period of time combined with low
energy tariffs: for instance, program the start
of the legionella cycle to the end of the
afternoon allowing the appliance to recover
during the evening and conclude the
disinfection during dawn.
Compress 3000 DW FOO
In situations where high consumption of hot
water are combined with shorter periods of
no consumption, the water speed selector
should be adjust to position "III" (see
section 4.9) in order to minimize the
probability of not having the disinfection
process concluded in due time (less than
48h after starting).
During the final period of the legionella
control cycle, when the electrical element
ensures the disinfection, the appliance will
remain silent while flashing LEG on the
display screen.
Furthermore, to increase the energy savings
and ensure that the water is not overheated,
the electrical element works intermittently.
Hence, there are periods when the electrical
heater remains off but the unit is still
performing the legionella disinfection.
After the LEG cycle has concluded, it is
possible that the appliance will starts
operating even though the temperature
displayed is above the selected set point.
This is an advanced comfort feature
incorporated in to the appliance to heat up
only the lower part of the tank (if required).
Therefore, this feature ensures a quick
temperature recovery for the lower half of
the storage tank when hot water is tapped
after a legionella disinfection cycle and the
top of the tank remains around the set point.
5.7.4 „PLUS“ - enhanced comfort function
The "PLUS" is a comfort function which is factory set to be
active but can be deactivated.
This function enables the appliance to automatically switch on
the electrical heater together with the heat pump cycle when
the air temperature is below 10 °C, the water temperature at
the bottom is cold, and a rapid temperature decrease at the top
of the tank is detected. Hence, by activating the auto boost, the
appliance will initiate a fast recover at the top of the tank to face
a potential lack of hot water. Once a hot water buffer is created
at the top, the appliance will proceed the recover by using the
heat pump cycle only.

5.7.7 “PHot” - photovoltaic
The "PHot" function allows the appliance to communicate with
a photovoltaic system to maximise energy savings. By enabling
the function, the appliance will operate mostly when the
photovoltaic energy is available, depending on the comfort and
override settings (see paragraphs ““PHCF” - Photovoltaic
comfort function” and ““PHor” - Priority of the photovoltaic

6 720 808 869 (2017/06)
38 | Appliance status information
enabled the appliance checks the bottom temperature every
time the top temperature drops 1 °C. If the bottom temperature
is below 40 °C the appliance re-heats the water until the
bottom temperature reaches 40 °C or the set point is achieved.
Instead of enabling this comfort function it is possible to define
a start condition (to be used when there is no photovoltaic
energy) to a value between 15 °C and TSet - 5 °C. The appliance
will start to operate when the top temperature drops below the
set value, regardless of the availability of energy generated by
the photovoltaic system.
When "on" is selected the minimum water temperature of 40 °C
is ensured for all water in the tank, regardless of the availability
of energy generated by the photovoltaic system. However, by
selecting a temperature between 15 °C and TSet-5 °C, the
appliance does not check the bottom temperature. Instead it
starts the operation when the top sensor registers a
temperature below the set value, regardless the bottom
temperature. This approach can compromise the comfort of
the user but will maximise the savings from the photovoltaic
system.

5.10 One shot boost and auto boost at negative
temperatures
In order to guarantee faster recovering times when the air
temperature is low and the thermal power of the heat pump
cycle decreases, the appliance is equipped with two boost
functions:
• auto-boost
• one shot boost
6720646160-08.1V
The appliance efficiency decreases when
boost is active, as part of the heating is
ensured by the backup electric heater. For
this reason, the auto boost is limited to very
low air temperatures and the one shot boost
is recommended to be used only when large
loads of hot water were drawn and a faster
recovering time is required to fulfill the next
hot water needs.
Note that, between 0 °C and 15 °C air
temperature when the boost is active the
heat pump cycle ensures only 1/3 to 1/2 of
the heating.
For higher air ambient temperatures the
fraction of the heating ensured by the heat
pump cycle increases due to the higher
thermal power.
Fig. 55
Auto-boost or one shot boost active
When the boost was activated automatically
(air temperature below 0 °C, activated by
PLUS function, LEG cycle running for more
than 24h) it can not be manually deactivated.
Auto-boost function
The auto-boost function switches on the electric heater
together with the heat pump cycle when the air temperatures
drops below 0 °C.
As soon as the air temperature rises above 0 °C the electric
element is switched off and the heating is ensured by the heat
pump cycle alone.
Below 0 °C air temperature, when the auto-boost is on,
typically only one third of the heating is provided by the heat
pump cycle.
The auto-boost is switched on as well, when the LEG
disinfection is not finalized in 24h.
One shot boost function
The one shot boost needs to be manually activated and is
automatically deactivated once the water reaches the set
point.
Activation and deactivation of the one shot boost function
▶ Press and hold the "+" and "-" buttons together for more
than 3 seconds to activate or deactivate the one shot
boost.
When the auto-boost function or the one shot boost function is
active, "FULL" is displayed on the HMI, alternating with the to
tank temperature.

Maintenance and repair
WARNING:
The water heater should be serviced by a
qualified professional and in accordance
with the Plumbing Standard AS/NZS
3500.4 and local authority requirements.
WARNING:
Before manually operating the relief valve,
make certain no one will be exposed to the
danger of coming in contact with the hot
water released by the valve. The water may
be hot enough to create a scald hazard. The
water should be released into a suitable
drain to prevent injury or property damage.
It is part of normal operation for the
Temperature and Pressure Relief valve to
discharge periodically. This is due to thermal
expansion in a closed water system. If this
discharge becomes excessive and runs
continuously, contact plumbing contractor.
Do not plug the relief valve outlet.
Properly maintained, your water heater will provide years of
dependable trouble-free and economic service.
It is suggested that a routine preventive maintenance program
is established and strictly followed by the user.
6.1
Periodic Inspection
It is recommended that a periodic inspection of the operating
controls, heating elements and wiring should be made by
service personnel qualified in electric appliance repair.
Most electrical appliances, even when new, make some sound
when in operation. If the hissing or singing sound level
increases excessively, the electric heating element may require
cleaning. Contact a qualified installer or service agent.
Additionally it is also recommended that the evaporator and
refrigeration circuit are checked every two years for dust and
residues. In dusty environments it may be necessary to have
the appliance checked and cleaned on a more regular basis.
6.2
Temperature and pressure relief valve (PTR
Valve)
At least every 6 months:
Compress 3000 DW FOO
▶ Lift and release the lever handle on the temperature and
pressure-relief valve, to make certain the valve operates
freely.
Allow several liters to flush through the discharge line to an
open drain.
Never replace the PTR Valve with one which has a higher
pressure rating than is specified for your water heater.
If the valve does not discharge water when the release lever is
opened or does not seal properly when release lever is closed,
replacement by an authorised person must be arranged
without delay.
The PTR Valve is not serviceable.
DANGER:
Before manually operating the relief valve,
make certain no one will be exposed to the
hot water released by the valve. The water
drained from the tank may be hot enough to
present a scald hazard and should be
directed to a suitable drain to prevent injury
or damage.
6.3
Flushing tank
A water heater’s tank can act as a settling basin for solids
suspended in the water. It is therefore not uncommon for hard
water deposits to accumulate in the bottom of the tank.
It is advisable to periodically flush the tank of these deposits by
draining and then refilling the unit (see section 6.4).
6.4
Draining the Water Heater
CAUTION:
Shut off power to the water heater before
draining water.
CAUTION: Risk of scalding!
Check the appliance's DHW temperature
before opening the safety valve.
▶ Wait until the water temperature has
dropped enough to prevent burns and
other damage.
Large volumes of water will drain from the
cold water inlet (>270 liters).
▶ Ensure proper drainage of water.
6 720 808 869 (2017/06)
44 | Maintenance and repair
▶ Close cold water supply.
▶ Open a hot water tap (preferably one installed at the same
level as the appliance) to relieve pressure and wait until
flow substantially decreases.
The pressure can also be released by manually opening the
PTR valve after ensuring all safety conditions are met to
avoid any scald hazard (section 6.2)
▶ After ensuring a proper drainage solution, remove cold
water inlet connection and wait until water is drained.
6.5
The water heater and piping should be drained if they might be
subjected to freezing temperatures. After a long shutdown
period, the water heater’s operation and controls should be
checked by qualified service personnel. Make certain the water
heater is completely filled again before placing it in operation.
Note: refer to the Hydrogen Gas Caution in
the Operating Instructions (section 5.1).
Clearing the Condensation Drain Tubes
The condensate drain is located at the back of the water heater.
If blocked, water will spill down the outside of the unit.
▶ Remove the condensate drain pipe.
▶ Clear any debris and reattach.
▶ Periodically inspect the drain line and clear any debris that
may have collected in the line.
▶ See Installation Instructions for more information.
6.7
Refrigerant circuit
NOTICE: Refrigerant leak!
▶ Repairs to the refrigerant circuit (e.g. to
the compressor, condenser,
evaporator, expansion vessel) may only
be carried out by an authorised
contractor.
6.8
▶ Arrange for an authorised person to inspect the anode and
replace it if required.
6.9
Checking/replacing the magnesium anode
The appliance is protected against corrosion
by an internal magnesium anode.
Vacation and Extended Shutdown
If the water heater is to remain idle for an extended period of
time, the power and water to the appliance should be turned off
to conserve energy and prevent the build up of dangerous
hydrogen gas.
6.6
Homes with salty or softened water supplies should consider
more frequent inspection. When in doubt consult a local water
heating professional.
WARNING: Damage to the appliance!
The magnesium anode must be installed
before commissioning the appliance.
WARNING: Damage to the appliance!
Appliances operated without this protection
are excluded from our warranty.
▶ Check the magnesium anode yearly and
replace it if required.
The internal wall of the DHW storage tank is coated with a
double glass lining. The coating is designed for normal quality
water (section 4.9.1, page 24). When using more corrosive
water, the warranty only applies if additional safety measures
(i.e. dielectric joints) have been taken, and the magnesium
anode is checked more frequently.
To check the protective anode:
▶ Isolate the appliance from the power supply.
▶ Isolate appliance from water supply.
▶ Open a hot water tap (preferable one install at the same
level as the appliance) to relieve pressure and wait until
flow substantially decreases.
The pressure can be released as well by manually open the
PTR valve after ensuring all safety conditions to avoid any
scald hazard (section 6.2)
▶ Remove the anode rod protective cap.
Anode Rod servicing
A water heater anode rod is the most important safeguard any
storage tank has against corrosion and premature failure.
Inspecting the anode rod is therefore very important.
Sacrificial anodes are designed to deteriorate overtime. Most
water heating industry professionals recommend inspecting
the anode yearly.

event before the end of the warranty period.
