General
Usage Range
The heat pump is designed only for
heating as well as generating service
water.
The heat pump can be utilized in newly
installed or existing heating systems
by complying with the usage limits as
defined by the AQUATOP planning
document.
E
Setup
The heat pumps can be set up on a
smooth, level, and plane surface
without the need of a base or pedestal.
The installation room must be dry and
frost-free. Rooms with much humidity
such as laundry rooms, etc. are not
very suitable for installing the heat
pump. The min. clearances must be
adhered with for all equipment to
ensure access in case of maintenance
and control tasks.
Function Principle of the
Brine-Wat er/Water-Wat er Heat Pump
The heat pump converts the heat
contained in the soil or rock
(groundwater) with a low temperature
into heat with a higher temperature.
This is achieved by routing the brine
liquid through a heat exchanger in the
soil (groundwater) and a pump to the
evaporator. The liquid working medium
in the evaporator boils and evaporates
at a low temperature and low pressure.
The evaporation heat required is drawn
from the brine liquid and returned to
the heat exchanger.
The evaporated working medium is
suctioned by the compressor and
compressed to a higher pressure.
The compressed, gaseous working
medium is fed to the condenser where
it is condensed at a high pressure and
high temperature.
The condensation heat is transferred
to the heating water and the temperature of that water increases.
The energy transferred to the heating
water corresponds with the energy
previously extracted from the soil
(groundwater) plus the small amount
of electrical energy required for
compressing the working medium.
Energy-Saving Use of the Heat
Pump System
Your decision to obtain a heat pump
heating system is an important contribution to saving the environment by
having lower emissions and reduce
your primary energy use.
Please observe the following points to
ensure your new heating system
functions efficiently:
L
The heat pump heating system must
be carefully dimensioned and installed.
L
Avoid unnecessarily high flow temperatures. The lower the flow temperature
on the heating side the more efficient
the heat pump is working. Make sure
the controller is set correctly and
properly.
L
Rush airing (several windows open at
once for short period) is to be preferred
over continuously leaving a small gap
open. Rush airing reduces the energy
consumption.

Charging Geothermal Heating Systems
Problems and Issues
Incorrect Brine Concentration
Flushing
Problems
Problems with charging a geothermal
heating system (GHS) with antifreeze
may occur occasionally and result in a
reduced capacity of the system or even
total system failure. Most problems are
as follows:
Dirt in the Circ ui t
Drilling companies generally strive to
fill only clean water into geothermal
heating systems. However, dirt may
reach the probe due to inattention.
This dirt can damage the circulating
pump or the evaporator of the heat
exchanger.
Insufficiently Mixed Brine Solution
If the correctly calculated antifreeze
volume is charged directly as a concentrate without corresponding mixing
device, individual probes may jam or
become completely disconnected due
to the viscosity of the concentrate.
Water without the required glycol
content circulates in the remaining
probes. Without the required glycol
content, the heat pump may freeze
already upon initial startup, which may
destroy the associated evaporator.
Incorrect Brine Concentration
In some cases, the detected glycol
concentration differed greatly from the
calculation.
This was mostly due to a lack of the
proper equipment to prepare the
mixture correctly. If the concentration
is too high, the heat pump's capacity is
reduced and works less efficiently.
The heat pump may also overheat.
An insufficient concentration (<20%)
may cause corrosion and frost damage.
Correctly Charging the GHS with the
Help of a Mixing Tank, Mixing
Equipment with Filter
All of the problems listed previously
can be avoided by properly charging the
GHS circuit. The right equipment can
make all the difference as well.
Use a mixing and charging tank to
charge the GHS circuit according to
the following requirements:
- Clean mixture
- Correct concentration:
- Homogeneous mixing
Flushing
Use filtered potable water and pressure to flush first the circulating pump
of the GHS circuit and the evaporator
and remove pollutants such as welding
beads, little stones, and dirt.
After closing a slider in the heat pump
circuit, each circuit of the GHS is
flushed one after the other.
A pressure of 2 bar is used to flush
a 140-m long ø 32 mm probe for
6 minutes as depicted below.

Charging Geothermal Heating Systems
Charging with Antifreeze
Correctly Charging a Geothermal Heating System Circuit
Charging with Antifreeze
After flushing, the entire geothermal
heating system circuit is to be filled
with clean tap water. Follow the steps
below to prepare the required concentration of antifreeze with a 100%
concentrate. For example:
The required antifreeze concentration
is 25% (ideal range is 25-30%) with a
140-m Duplex® ø 32 mm BHE.
(Content per meter = 4 pipes x 10 dm,
length x 0.13 dm,
inner radius
2
x rr = 2.12 l/m.)
Correctly Charging a Geothermal
Heating System in 14 Steps
1. Flush the GHS circuit as described
on page 18.
2. Calculate the probe volume acc. to
table above. One GHS (GHS
ø 32 mm) has 2.12 l/m content per
meter. This yields the following
GHS content for our example:
140 m x 2.12 l/m = 296.8 liters
(297 l). Do not forget the content of
the connection lines up to the heat
pump, 30 liters in our example.
This results in a total system content
of 297 liters + 30 liters = 327 liters.
3. Required volume of 100% anti freeze concentrate:
25% of 327 liters = 82 liters.
4. Close the sliders to the heat pump.
Remove the drain hose from the
tank and place in drain.
5. Open the sliders of the GHS – if
several probes have been
installed, one slider after the other
is opened during charging.
6. Fill the mixing tank with an approx.
mixture of 1:1 of antifreeze
concentrate and fresh water.
Depending on tank size, not all of
the 82 liters of concentrate fit into
the tank (see calculation, item 3).
7. Switch the feed pump on.
As soon as the tank begins to
empty, continuously fill in the
remaining antifreeze concentrate
and additional fresh water into the
mixing tank at a ratio of approx.
1:1. Make sure that always at least
40 liters of mixed reserve remains
in the tank. Volume markers can
be attached to the edge of the
tank to help you determine its
volume.
8. The feed pump is allowed to run
until the entire antifreeze
mixture – except for the 40 liters
reserve – are filled in and then is
switched off at once. Excess tap
water drains from the drain hose
into the drain.
9. Now insert the drain hose into the
tank, turn the feed pump back on,
and allow it to run until glycol and
water are thoroughly mixed. This
takes about 6-times to 8-times as
long as it takes for flushing (see
diagram, item flushing).
10. Close charging valves at drain
hose and then those at the
geothermal heating system
distributor. The excess pressure
valve (2.5 bar) routes the excess
mixture back into the tank. Shut off
feed pump. About 40 liters remain
in the tank. Some of the mixture
was absorbed by the expansion
of the geothermal heating system.
11. In case of relatively long geo thermal heating systems and
insufficiently mixed mixture, the
excess pressure valve at the tank
is triggered and thereby intensifies
mixing.
12. If several GHSs are combined into
one system, the second, third, etc.
GHS is first flushed and then
charged individually until all have
been processed.
13. Once all geothermal heating
systems are charged, the eva porator and the brine circulating
pump must be charged next.
All sliders to the geothermal
heating systems are closed for
this purpose and the sliders to the
evaporator are opened.
The remaining mixture is now
carefully pumped via the slider at
the filling hose. Allow water in the
circuit to escape via the drain
hose. As soon as the glycol
mixture emerges as the drain hose
(color change), close the corre sponding valve and allow the
pump pressure to charge the
expansion vessel (2.5 bar). Then
close the valve at the filling hose.
The system is now charged with
the correct concentration and
correct operating pressure without
introducing pollutants to the
system.
14. Now carry out a pressure test.
This test should be performed
over an extended period to avoid
the hassle of finding leaks later on.
Note: Antifreeze mixtures are
more likely to result in leaks earlier
than water alone!

T roubleshooting A QUATOP LOGON WP
Malfunction
Cause
Remedy, Action
106: Source temperature too
low B-W HP
Brine output temperatures too low (parameter
2816, -5°C)
A1 Low volume flow
A2 Geothermal heating system badly charged
A3 Geothermal heating system comp. not in order
A4 Slider closed
A5 Pump not running
A1 Check pump output
A2 Vent geothermal heating system
A3 Set flow control
A4 Open slider
A5 Check thermo relays, phases and relays
106: Source temperature too
low W-W HP
While the HP is running and the groundwater
return temperature at thermostat, built in
downstream of HP, is less than 3°C
(parameter 2815, corresponding setting 3°C),
switching to frost protection.
A Frost protection thermostat incorrectly set
or defective.
B Groundwater volume flow too low.
The module switches the respective unit to
the safety state when a malfunction or error
occurs.
A Check frost protection thermostat for function
or not properly set, replace if needed.
B With too low groundwater output
temperatures, the system cannot be operated.
Min. water temperatures were not determined.
B1 Check filter for dirt
B2 Check evaporator for dirt
B3 With existing intermediate circuit, check function
of intermediate circuit, check plate exchanger
for dirt
B4 Check flow switch setting (triggers too late)
B5 Check water level in well and check its
dropping during operation.
107: Hot gas compressor (B 81) A Too little coolant
B Compressor leak
A Top off coolant
B Replace compressor
The cooling technician must be called in these cases.
222: HP at HP operation, high
pressure malfunction
High pressure compressor
High-pressure pressure controller triggered in
cooling circuit. No heat.
A In heating mode
A1 Insufficient flow rate
A2 Slider closed
A3 Heating circulation pump not running
A4 Overflow valve incorrectly set
A5 Heating curve set too steep
B High-pressure pressure controller actuated
too early
The module switches the respective unit to the
safety state when a malfunction or error occurs.
A1 Check flow heating water (
O
T =3-5 K)
A2 Open slider. Check flap valves
A3 Make heating circuit pump functional
again/replace pump.
A4 Repeat overflow valve setting procedure
A5 Set heating curve lower
B If A can be precluded, check at which heating
water output temperature from the heat pump
the high-pressure pressure controller is actuated.
If the switching point is significantly below 65°C,
it is possible that
B1 The switching point of the pressure controller is
too low (the pressure controller setting has
changed)
B2 The amount of coolant is too high
The cooling technician must be called in these
cases.

Cause
Remedy, Action
223: HP when starting HC
High pressure malfunction
when starting heating circuit.
A Water in system too cold. A Below 10 °C: Increase temperature in system
with electr. immersion heater.
224: HP when starting potable
water heating
High pressure malfunction
when starting PWH.
Service water operation.
A Boiler charging pump/3-way valve not running
B Air in system
C Slider closed
D Heat exchanger too small
E Sensor positioned incorrectly (too low)
A Unblock pump/3-way valve or replace
B Vent system
C Open slider, check flap valve
D Check with retailer
E Mount sensor correctly
226: Coil guard compressor A Phase interrupt (compressor is getting hot) A Check all three phases (wait until
coil guard has cooled down, this may take
several hours).
225: Low pressure malfunction Low pressure compressor E9
Low pressure pressure controller triggered in
cooling circuit.
A Insufficient flow of brine-water in evaporator
B Leak in cooling circuit
C Pressure controller defective
D Plugged filter
E Defective or blocked injection valve
F Incorrect amount of coolant
A
A1 Blocked brine pump, make brine pump
function again
A11 Defrost thickened brine in evaporator
(remove insulation, use hairdryer to melt or let
sit for 1 day)
A2 In case of inhomogeneous brine mixtures, the
brine may become thickened in the evaporator.
A21 Better mixing of brine
B If all items above have been checked and of the
compressor switches to low pressure malfunction
within a few seconds after being started, then the
cooling circuit has a leak.
Oil residues in the unit are another indicator of a
leak in the cooling circuit (do not mistake oil for
brine).
B1 In case of a leak in the cooling circuit,
the cooling service technician must be called.
C Check switching point (important: depends on
coolant type)
D Measure temperature upstream and downstream
of filter (AT max 2 K)
E Check or replace injection valve
Check and insulate sensor
F Empty and recharge acc. to type plate.
