EhpocaGEO System
Ehpocageo, the range of heat pumps designed to heat,
cool and produce domestic hot water in a modern,
independent manner and at a low cost.
The ehpocageo heat pumps use the constant temperature
of the ground, through coils or geothermal probes, to
extract and transfer energy to the ground.
The DC Inverter technology allows great power regulation
precision to be achieved with maximum efficiency even
at partial loads. The latest generation ehpocageo inverter
board allows for total correction of the power factor
SMART CONTROL UNIT
The electronic Smart Control is entirely and exclusively
made for ehpocageo, and controls and optimises all
operating aspects of the system.
LOCAL ZONES CLIMATE CONTROL
Ehpocageo connects to peripheral boards that allow total
zone climate control (summer and winter temperature
and relative humidity). All information is transmitted
from the individual boards to the central unit for the
water temperature to be adjusted. In this way, perfect
thermoregulation is balanced with energy saving.
TOUCH SCREEN THERMOSTAT
Each zone controlled by ehpocageo is served by an
advanced chronothermostat-type touch screen with the
temperature and relative humidity sensor on board.
GEO-SOLAR FUNCTION
The exclusive geo-solar function is an example of using
renewable sources, which sees that exchange occurs via
the geothermal probes if the solar panels are at a lower
temperature than that required by the domestic hot water
circuit and the heating system.
FREE COOLING FUNCTION
Another important function is that of free cooling, in which
the cooling compressor is off, while the circulation pumps
circulate the water directly between the geothermal probes
and the system.

GENERAL INFORMATION
Description of the appliance
• The structure is made of thick galvanised epoxy
painted sheet metal. The panels of the compressor
compartment are made totally soundproof with
high sound absorption plates. The compressor and
hydraulic compartments and the electric panel are
accessed via the removable front panel.
• All the models are equipped with hermetic TWIN
ROTARY INVERTER DC type compressors, which are
controlled by exclusive TOTAL PFC circuit boards,
thereby allowing for the exact energy required by
the actual demand of the building to be supplied
precisely, guaranteeing maximum efficiency even at
partial loads. Furthermore, this technology eliminates
high peak currents, which are typical in ON/OFF
compressors.
The compressor is mounted on rubber supports to
eliminate any vibration.
• The heat exchangers are plate-type, made of AISI
316 stainless steel and coated with a closed cell anticondensate material.
• The electronic expansion valve is made of fine
materials (AISI 316L and engineering polymers), and
thanks to the adjustment being controlled by the
same circuit board that controls the compressor,
guarantees proportional modulation that can stabilise
and maintain appliance operation constant in very
short times, allowing significant energy savings
compared to other solutions.
• The refrigerant circuit is entirely made of copper and
insulated with a closed-cell foam pipe and works with
environmentally friendly R410A refrigerant. The circuit
is complete with: a bi-flow dehydrator filter, a cycle
reversing valve, high and low pressure switches, a
pressure transducer to control the condensation and
evaporation in the water-run versions only, and a low
pressure transducer used to control the overheating
of the electronic expansion valve.

• The hydraulic circuit of the appliance is divided into
the primary system heat exchanger, the disposal heat
exchanger (geothermal or water-run) and the high
temperature de-superheater for DHW use.
The heat exchanger intended for the primary system
can produce hot or cold water (also with the freecooling function, in which the cooling compressor is off
and a pump circulates the water directly between the
geothermal probes and the system, thereby lowering
the internal temperature with the power consumption
very close to zero thanks to the presence of two
specific 3-way valves, V5 and V6) through a heat
exchanger with a large surface area and low pressure
drops and has an A class high head inverter circulation
De-surriscaldatore
pump (up to 12m of water column) and a water flow
verification device (differential pressure switch).
The disposal heat exchanger also has a dedicated
heat exchanger and the geothermal version has an A
class high head inverter circulation pump (up to 12m
of water column), while the water-run disposal version
includes the two-way modulating valve. Through the
specific 3-way V7 valve it can implement the exclusive
geo-solar function, which during poor insolation
periods in winter regenerates the geothermal probes
(which are normally at a temperature close to 0°C thereby improving the COP significantly) and recovers
the heat from the solar tank. The water flow verification
device (differential pressure switch) is present in both
7
EN
GENERAL INFORMATION
cases.
By means of an oversized heat exchanger, the
DHW de-superheater allows water to be produced
at a high temperature (up to 60°C) with total energy
recovery during normal appliance operation, whereby
the system is heated or cooled, has an A class high
head inverter circulation pump (up to 8m of water
column) and a 3-way V1 valve, which allows the heat
of the water to be recovered from the solar tank while
keeping the compressor off.

There are also 3 different valves to drain the water
totally or partially from the circuits and a system
hydronic pressure gauge.

Installation method
Carefully follow the instructions given in this manual for the
installation to be successful and the operating performance
to be optimal. Failure to apply the mentioned regulations,
which may cause the equipment to malfunction, relieve
INNOVA from any form of warranty and any liability for
damage caused to persons, animals or objects. It is
important for the electrical system to be set up according
to the regulations in force, in compliance with the data
provided in the Technical data chapter and for it to have a
proper earthing system. The appliance must be installed in
such a way as to facilitate maintenance (full front access),
as well as the air vent valves (inertial tank and pipes) being
accessed by simply removing the front panel.

Hydraulic connections
The choice and installation of components is decided by
the installer, who must operate in compliance with good
workmanship and current legislation. Before connecting
the pipes, ensure they are free from stones, grit, rust,
debris or any foreign bodies that may damage the system.
It is good practice to create a by-pass in the system so
that the appliance does not have to be disconnected in
order to wash the plate heat exchanger.
The connecting pipes must be supported, so that their
weight does not rest on the appliance.

The hydraulic connections should be completed by
installing:
- air relief valves at the highest points of the pipes;
- flexible elastic joints;
- on/off valves.
The hydraulic connections can be set up either facing the
wall (thereby hiding them under the upper panel) or facing
upwards by removing the pre-cut sheet metal part on the
panel.

The nominal minimum diameter of the connection
pipes must be 1”. To allow the maintenance and
repair operations it is indispensible that each hydraulic
connection is fitted with respective manual closing
valves.
The maximum pressure losses allowed are those defined
in the technical data paragraph.Should more head be
necessary due to high pressure loss in the system an
external pump must be added with relative inertial vessel.
The distribution pipes for the cooled water must be
adequately insulated with expanded polyethylene or similar
material with a thickness of at least 13mm.

Even the interception valve, the curves and union joints must
be adequately insulated.
To avoid pockets of air inside the circuit we strongly
recommend including automatic or manual breather
devices in all points (high pipes, siphons etc) where air can
accumulate.
If the mains water pressure is more than 3 bar, install a
pressure reducer on the supply.
The unit is supplied with three sieve filters with 0.5 mm links.
Install them on the water inlets pipeline of the unit (return from
the system).

Storage tanks
Appropriate water storages should be installed in the system,
solar and DHW circuits for the installation to be correct.
The system circuit must guarantee minimum water content
of 10 litres per kW of heat output through an inertial tank. A
2.9
content of 30 litres per kW is recommended in any case to
optimise the efficiency at partial loads.
Filling the system
Once the hydraulic connections have been completed the
system will have to be filled. It will then be necessary to
simultaneously release the air from the inside of the pipes
and device itself.
During these operations, the machine must be
disconnected from the mains power supply.
If an external auxiliary pump is used it must also be
switched off.
The working pressure of the system must not exceed
1.5bar with the pump switched off. To check any possible
leaks from the system when setting up we suggest you
increase the test pressure and then reduce it successively
it to reach the working pressure.
Once all the electrical connections have been made and
the circulation pump is activated, check that there are
no pockets of air in the system. If this happens, stop the
pump, release the air and re-start, repeating the procedure
until it is all cleared. To avoid dangerous cavitations that
could damage the pump and make the entire system
less efficient, the inlet pressure with the pump switched
on must not be less than 0,6 bar, measurable with the
manometer on the device.

2.11 Setting the circulation pump
The appliance has high efficiency wet rotor circulation
pumps suitable for all heating and air-conditioning
systems with a temperature range from -10°C to +110°C
that, due to the use of specific synchronous motors - with
permanent magnet rotors adjusted by an A class inverter
- guarantee energy savings of up to 80% when compared
to standard pumps.
Furthermore, the control electronics guarantee the
automatic adjustment of performances to the changing
operating conditions of the hydraulic system.
A regulator is present on the front part of the pump body
that allows for the selection of the maximum pump head,
based on the effective system requirement, and for that
of the operating mode with variable heads Δp-v (set by
default) in which the electronic system varies the head
developed by the pump between the set value and half of
this upon the varying of the water flow rate or the constant
head mode Δp-c
where the pressure difference
generated by the pump is kept constant at a set value
throughout the admitted flow rate range.
The maximum head value of the heating/cooling MP2
system pump should be set with the potential of the
compressor at 100%, with all the dispensing valves
open and the utilities turned on, verifying the temperature
difference between the system flow and return (TI20 and
TI21), which must be between 4 and 7°C, querying the
user menu.

The maximum head value of the disposal MP3 pump
should be set with the potential of the compressor at 100%
and all probe field valves open, verifying the temperature

querying the user menu.
The maximum head value of the DHW MP4 pump should
be set with the potential of the compressor at 100%,

2.13 Water-run disposal circuit
The disposal circuit in this version has a 2-way modulating
valve, driven directly by the Smart Control, which based
on the condensing/evaporation pressure value detected
by the transducer PR2, allows the inflow to the heat
exchanger of the amount of water that is necessary for the
system to be adjusted correctly so as to minimise power
consumption and maximise performance.
The KV of valve V9 is used:
Kv (m3/h con ∆p = 100kPa = 1bar) = 32
Upon initial start-up, the specialized technician will have
to obtain the reference values of the system’s water using
appropriate test kits.

Bore or groundwater not from water supply system should
always be carefully analysed and if necessary treated with
appropriate systems. If installing a softener, in addition to
following the manufacturer’s guidelines, adjust the hardness
of the outlet water to no lower than 5°F (also run pH and
salinity tests) and check the concentration of chlorides at
outlet after regeneration of resins.
2.14 System drain
Before emptying, make sure that the shut-off valves of the
heat pump and the top-up valves are closed.
Remove the drain cap, connect a drain pipe and open the

USE AND MAINTENANCE
Appliance operation
Solar/DHW recovery (enabled by PC1)
The DHW
and solar
lsymbols flash simultaneously.
If the solar buffer reference temperature TI3 is greater than
that of the DHW tank TI9 + 6°C (PF184), the compressor
goes off, the solar/DHW V1 recovery valve switches its
position and the MP4 DHW pump starts after 30 seconds
(PF176). This situation is maintained until TI9 reaches
68°C (PF167-PM002). This function is active both in winter
and in summer, and is independent of the compressor
operation, which can be used for functions required by
the system.
DHW tank heating
The DHW
symbol lights up and flashes when the
compressor is active.
SIf the DHW tank reference temperature TI9 drops
below the Set-point set in the user menu - hysteresis
at 2.5°C (set to PF93), the MP4 DHW pumps and the
MP2 disposal pumps start and 40 seconds after verifying
that the respective flow switches have closed, the
inverter compressor starts and reaches the maximum set
frequency (PM56) within 3 minutes. When temperature TI9
rises and reaches the hysteresis range, the compressor
modulates its frequency until it switches off at set-point.
This function has priority over the heating (unless you
press the
key that inhibits this priority for 90 minutes
(PF95), whereas it can be active together with the cooling
function.
ECO Function
Press the corresponding
key for the appliance, boiler
or resistance operation that heats the DHW to be inhibited
for 12 hours (PF100), thereby forcing solar/DHW recovery.
This can be implemented when it is particularly sunny
and the user can choose to save on energy consumption
(electricity or fuel), leaving only the solar energy to heat
the DHW.
When this function is active both in winter and in summer,
the compressor can be used for other functions required
by the system.
When this function is activated, the solar tank is used for
solar/DHW recovery until the DHW set-point is reached
and then it can activate the solar/system recovery while
the geo-solar function is inhibited.
Solar/system recovery (enabled by PC2 and active only in winter)
The system
and solar
lsymbols flash simultaneously.
If the system buffer reference temperature TI6 is greater than
that of the TI9 DHW tank + 6°C (PF182), the compressor
goes off and the solar/system P2 recovery pump starts.
This situation is maintained until TI6 drops below TI9 +3°C
(PF183) or the system set-point is reached. This function
is only activated if the DHW set-point is reached (there will
never be simultaneous operation with the compressor and also boiler or resistance - active for DHW).
System heating
The system
symbol lights up and flashes when the
compressor is active.
This function is inhibited by the simultaneous DHW request
(which is priority), but precedence can be inverted for 90
minutes (PF95) by pressing the Fast Heating key.
The system heating function is carried out with 4 different
modes depending on the system configuration (set via PC
parameters)
System tank with no configuration
Probe TI20 shown on the Smart Control interface display.
The function is only active if the remote digital input DI3 is
closed. With an open input, the appliance only produces
hot water.
The climate control of the outdoor temperature TI31 is not
active.
The water set-point (visible in the State menu display,
Plant_Temp_Need item) is set by parameter PF8.
When the water output temperature of the system heat
exchanger TI20 drops below this set-point - hysteresis
at 3°C (set by PM5), the MP2 system pumps and the
MP3 disposal pumps start and 40 seconds after verifying
that the respective flow switches have closed, the
inverter compressor starts and reaches the maximum set
frequency (PM03) within 3 minutes. When temperature
TI20 increases and reaches the hysteresis range, the
compressor modulates its frequency until it reaches the
minimum set-point allowed (PF140) and keeps it until
TI20 reaches 50°C (PF150) after which it is switched off
and after 60 seconds (PF139) the MP2 and MP3 pumps
switch off too. The value of parameter PF52 must be set
greater than or equal to PF8 and PF150.

Configuration with system tank but without any zone board
Probe TI6 shown on the Smart Control interface display.
The function is active if the remote digital input DI3 is
closed. With an open input, the appliance only produces
hot water.
The climate control of the outdoor temperature TI31 is not
active.
The water set-point (visible in the State menu display,
Plant_Temp_Need item) is set by parameter PF8. When
the winter system buffer reference temperature TI6 drops
below this set-point - hysteresis at 3°C (set by PM5),
the MP2 system pumps and the MP3 disposal pumps
start and 40 seconds after verifying that the respective
flow switches have closed, the inverter compressor starts
and reaches the maximum set frequency (PM03) within
3 minutes. When temperature TI6 rises and reaches the
hysteresis range, the compressor modulates its frequency
until it switches off at set-point and after 60 seconds
(PF139) the MP2 and MP3 pumps switch off too.
Configuration with system tank and zone board/s but with no Touch screen
chronothermostat
Probe TI6 shown on the Smart Control interface display.
The actual water set-point (visible in the State menu display,
Plant_Temp_Need item) is calculated by the software
according to the algorithms defined by the climate control
and the actual distance from the ambient set-point (set by
parameters PF13 for Zone a and PF14 and PF15 for Zones
b and c) at a temperature in the various zones detected
by probes TI16 positioned in the environments and may
vary between the values 25°C and 50°C set by parameters
PF149 and PF150.
When the winter system buffer reference temperature
TI6 drops below this water set-point - hysteresis at 3°C
(set by PM5), the MP2 system pumps and the MP3
disposal pumps start and 40 seconds after verifying that
the respective flow switches have closed, the inverter
compressor starts and reaches the maximum set frequency
(PM03) within 3 minutes. When temperature TI6 rises and
reaches the hysteresis range, the compressor modulates
its frequency until it switches off at set-point and after 60
seconds (PF139) the MP2 and MP3 pumps switch off too
Adjusting zone pumps and valves in heating
Probe TI6 shown on the Smart Control interface display.
The actual water set-point (visible in the State menu
display, Plant_Temp_Need item) is calculated by the
software according to the algorithms defined by the
climate control and the actual distance from the set-point
set on the Touch screen zone chronothermostat at the
ambient temperature in the various zones detected by the
probe inside the chronothermostat and may vary between
the values 25°C and 50°C set by parameters PF149
and PF150. When the winter system buffer reference
temperature TI6 drops below this water set-point hysteresis at 3°C (set by PM5), the MP2 system pumps
and the MP3 disposal pumps start and 40 seconds after
verifying that the respective flow switches have closed, the
inverter compressor starts and reaches the maximum set
frequency (PM03) within 3 minutes. When temperature TI6
rises and reaches the hysteresis range, the compressor
modulates its frequency until it switches off at set-point
and after 60 seconds (PF139) the MP2 and MP3 pumps
switch off too.
Adjusting zone pumps and valves in heating
Pumps P1a, b and c only start if the system buffer
reference temperature TI6 is greater than 20°C (PF53 for
Zone a and PF54 and PF55 for Zones b and c). The return
temperature from the zone systems TI13 is set through the
modulation of the MV1 valves according to the algorithm
shown below that verifies the actual distance from the setpoint of the ambient temperature in the different zones.
Different values can be set for adjustment parameters
PF25, 26 and 27 and PF110, 111 and 112 according to
the different types of system (floor, fan coils).
The adjustment of each zone is active if the DI6 presence
contact is closed or the ambient air set-point is lowered
to value PF16 for Zone a and PF17 and PF18 for Zones
b and c.

USE AND MAINTENANCE
Total DHW recovery function
If during the system heating or cooling the DHW tank
reference temperature TI9 is higher than the set-point but
lower than 50°C set by parameter PF94 and 2 minutes
after the compressor start-up at least 10°C lower than the
desuperheater output temperature TI26, the MP4 pump
is kept on (simultaneously with the MP2 and MP3 pumps)
so as to make the DHW exchanger run as desuperheater
with total recovery, thereby producing water at a high
temperature. The function terminates if the difference
between TI26 and TI9 drops below 5°C for 2 minutes or
the request for heating or cooling ceases or TI9 reaches
the threshold set by PF94.
This function is enabled by parameter PF162.
EH emergency heating function
Pressing the corresponding
key for the appliance
operation that heats both the DHW and the system to be
inhibited until you manually exit the function, forcing the
boiler or the resistances available to be used.
Solar tank and circuit adjustment
The MP1 DHW system modulating pump runs according
to the temperature read by the T1 solar manifold water
probe according to the chart below:
Start at the minimum speed (10% software-defined) when
T1 is hotter than the high temperature of the solar tank
TI2 + 5°C (PF76), the flow rate increases in the range
TI2 + 10°C (2 • PF76) and keeps the maximum value
up to 71°C (PF77-PF76) and then slows down in the
subsequent 5°C and switches off at 80°C (PF77+PF79).
At high manifold temperatures it restarts at 85°C (PF78PF80) and switches off at 90°C (PF78).
When TI1 decreases, the pump performs the reverse
cycle until it is switched off when TI1 is lower than TI2.
If the high temperature of the solar tank TI2 exceeds 80°C
(PF77+PF79), the AL21 High solar tank temperature
appears on the display and the EV3 solar system drain
valve opens to protect the circuit from excessive pressures
and temperatures. It closes again below 76°C (PF77).
The water temperature probes in the solar manifold TI1
and at the bottom of the solar tank TI3 verify the AL26 solar
tank anti-freeze. If TI1 detects a temperature lower than
3°C (PF81), the MP1 pump is activated at the minimum
speed, whereas if TI3 drops below 3°C (PF81), the R3
solar tank resistance is activated (if present and enabled
by PF83). The alarm reverts with hysteresis at 4°C (PF82
for the manifold, PF84 for the tank).
Geo-solar function
Flashing solar symbol .
Flashing solar symbol. (IMG)
During poor insolation periods in winter, through the
switching of the 3-way solar recovery valve/V7 probe and
the MP3 disposal pump start-up, the algorithm regenerates
the geothermal probes (which are normally at a temperature
close to 0°C - therefore, improving the COP significantly),
thereby recovering the heat from the solar tank.
The function is activated in 3 different modes: night, morning
and afternoon:
From 23:00 to 7:00 (parameter 105) solar recovery begins
freely with or without the DHW or system heating request
when the solar buffer reference temperature TI3 is less
than that detected by the TI9 DHW reference probe + the
hysteresis set by parameter PF184 (6°C) and that detected
by the TI6 system reference probe + the hysteresis set by
parameter PF182 (6°C) or with any T3 temperature (even
greater than the other 2 tanks) if the DHW and system setpoints are met, the upper temperature of the solar tank
detected by TI2 is greater than the geothermal exchanger
input temperature TI25 + 8°C (hysteresis set by PF86), the
upper temperature of the solar tank TI2 is greater than 18°C,
set by the software and the geothermal exchanger input
temperature TI25 is less than the maximum temperature of
25°C set by parameter PF88.
It ends when the upper temperature of the solar tank TI2
drops below the geothermal exchanger input temperature
TI25 + 2°C (calculated by the PF86/4 formula) or the upper
temperature of the solar tank detected by TI2 drops below
18°C or the geothermal exchanger input temperature TI25
becomes greater than 25°C (PF88) + the hysteresis set by
parameter PF89 (3°C) or if there is a request for DHW or
system water and the solar buffer temperature TI3 is greater
than is required for one of the 2 tanks.
From 7:00 (PF105) to 13:00 (PF106), the function is only
activated if the night mode conditions are met and only
during compressor operation (for system or DHW heating
request). In this case, the system expects a request before
using the water from the solar tank, and therefore, if T3 is
greater than one of the other 2 tanks, as soon as there is a
request, it will simply be poured into the other tank whereas,
if T3 is less, it will actually be sent to the geothermal probes.
After 13:00 the function is active - with the same rules set
for the morning mode - only if at that time the solar tank
temperature TI2 has remained over the DHW set-point for at
least 2 hours (PF107) without the compressor starting-up.
The function is enabled via parameter PF90 and has a
start-up delay of 15 minutes (parameter PF87). If the ECO
function is active, this function is inhibited

The system
symbol lights up and flashes when the
compressor is active.
This function can be inhibited by parameter PM59 set to
1 and can be active simultaneously with the production of
DHW and in this case, the MP4 pump will go on instead
of MP3, thereby making the desuperheater run as a
capacitor and the
symbol will also begin to flash.
The system cooling function is also carried out with 4
different modes depending on the system configuration
(set via PC parameters).
System tank with no configuration
Probe TI20 shown on the Smart Control interface display.
The function is active if the remote digital input DI3 is
closed. With an open input, the appliance only produces
hot water.
The water set-point (visible in the State menu display,
Plant_Temp_Need item) is set by parameter PF9.
When the water output temperature of the system heat
exchanger TI20 is greater than this set-point + hysteresis
at 3°C (set by PM6), the MP2 system pumps and the
MP3 disposal pumps start and 40 seconds after verifying
that the respective flow switches have closed, the
inverter compressor starts and reaches the maximum set
frequency (PM04) within 3 minutes. When temperature
TI20 decreases and reaches the hysteresis range, the
compressor modulates its frequency until it reaches the
minimum set-point allowed (PF140) and keeps it until
TI20 reaches 6°C (PF158) after which it is switched off
and after 60 seconds (PF139) the MP2 and MP3 pumps
switch off too.

the MP2 system pumps and the MP3 disposal pumps
start and 40 seconds after verifying that the respective
flow switches have closed, the inverter compressor starts
and reaches the maximum set frequency (PM04) within 3
minutes. When temperature TI5 drops and reaches the

PF20 and PF21 for Zones b and c) at a temperature in the
various zones detected by probes TI16 positioned in the
environments and may vary between the values 6°C and
20°C set by parameters PF158 and PF159. When the
summer system buffer reference temperature TI5 is greater
than the water set-point + hysteresis at 3°C (set by PM6),
the MP2 system pumps and the MP3 disposal pumps
start and 40 seconds after verifying that the respective

Adjusting zone pumps and valves in cooling
Pumps P1a, b and c only start if the summer system buffer
reference temperature TI5 is less than 32°C (PF56 for
Zone a and PF57 and PF58 for Zones b and c). The return
temperature from the zone systems TI13 is set through the
modulation of the MV1 valves according to the algorithm
shown below that verifies the actual distance from the setpoint of the ambient temperature in the different zones.
Different values can be set for adjustment parameters
PF28, 29 and 30 and PF123, 124 and 125 according to
the different types of system (floor, fan coils).
An anti-dew check can be performed for floor systems in
particular, thanks to a humidity probe in the touch screen
thermostat zone available as accessories, thereby allowing
parameters PF44 for Zone a and PF45 and 46 for Zones
b and c to be set. In this case the modulation of the MV1
valves is based on the input temperature readings from
the TI10 zone systems to prevent them from dropping
below the calculated dew points.
The adjustment of each zone is active if the DI6 presence
contact is closed or the ambient air set-point is increased
to value PF22 for Zone a and PF23 and PF24 for Zones
b and c.

Function enabled by PF162 set to 1.
If you DHW set-point greater than the switching threshold
set by parameter PF94 is set, the compressor is switched
off at this value after the boiler (or the resistances,
depending on parameter PC03 and PC05 settings) brings
the DHW tank reference temperature TI9 up to the setpoint. In this case the compressor/resistance switching
also occurs if PF160 is set to 1.

In the event of a flow switch alarm, the compressor
is stopped (and the alarm appears on the display) 30
seconds (set by software) after the flow switch is opened.
The pump remains active for another 90 seconds (PF168),
then switches off for 60 seconds (PF169), then restarts for
another 90 seconds and if the flow switch does not close,
it switches off again for another 60 seconds (PF169) and
so on until the maximum number of repetitions is reached
after which the alarm must be reset manually. If during the
ON period of the pump, the flow switch closes, the alarm
