Indicates a situation which could result in property damage or equipment malfunction. It may also
indicate whether the practice is the commendable for the equipment.
DANGER!
Indicates an imminent or potentially hazardous situation which, if not avoided, could result in death or
personal injury. It may also warn you about unsafe practices.
Page 5
2. SAFETY ISSUES
The indications outlined in this section cover important issues on your safety; please follow them carefully.
2.1. REFRIGERANT CIRCUIT
The refrigerant circuit uses R410A as working fluid. This refrigerant is eco-friendly, as it is chlorine-free and, therefore, does not contribute to ozone layer depletion. However, any action on the refrigerant circuit should be carried out by authorized personnel only and in accordance with the applicable local regulations and the instructions outlined in this manual.
TOXICITY
Under normal operating conditions, the coolant toxicity is nil. However, in spite of its low toxicity, it could result in personal injuries under unusual equipment operating conditions.
In its gaseous state, the refrigerant is denser than air, thus tending to accumulate in lower levels. If
the equipment is installed in a location where it is possible that refrigerant vapour accumulates at ground level, it should be well ventilated.
DANGER!
In the event of accidental refrigerant leakage, avoid touching the leaking area directly. Otherwise,
serious freezer burns could occur. The maximum operating pressure of the cooling circuit is 4.2 MPa (42 bar). Avoid touching the pipes, the compressor or other refrigerant circuit parts during or immediately after
operating the heat pump. These could be at high or low temperature, and touching them could result
in heat or freezer burns. If you need to touch these pieces, allow sufficient time for temperatures to
stabilize and use protective gloves to prevent injuries.
DANGER!
All installation and maintenance work must be performed by an authorized technician following the
indications outlined in this manual. An improper installation or misuse of the equipment could result in electrical shock, short circuits,
working fluid leakage, fire or other injuries and/or property damages. If you are unsure about the
equipment installation, maintenance or operation procedures, please contact your local dealer or
customer services for advice. If you detect unusual performance in the unit, please contact your local dealer or customer services
to resolve your concerns. This equipment must not be operated by persons suffering any type of physical, sensorial or
psychological disability, children or persons lacking the necessary experience or knowledge, unless
they have been given supervision or instruction concerning use by a person responsible for their
safety. During the installation, maintenance or commissioning of the heat pump, please always wear
appropriate personal protective equipment. Keep all plastic packaging bags away from children to prevent suffocation.
Page 6
Direct exposure of the refrigerant to flames produces toxic gas. However, this gas can be detected
by its smell in concentrations well below the allowable limit. If you detect an unusual smell, evacuate and ventilate the area until you are sure that the gas has been fully eliminated.
In the event of accidental refrigerant leakage, ventilate the area immediately. Anyone who has had contact with the refrigerant vapour should evacuate the area immediately and
breathe fresh air.
FLAMMABILITY
Under normal conditions, there is no risk of explosion or combustion of the refrigerant contained in the circuit.
SERVICING AND SCRAPPING In order to repair the refrigerant circuit, the coolant contained within should not be released to the atmosphere, but it should be recovered and destroyed in treatment plants intended for such purpose.
Considering the fact that the R410A is a mixture, in the event of leakage, the extra refrigerant should be filled in liquid state. Filling the refrigerant in gaseous state alters its composition and might cause heat pump malfunctions.
Before dismantling the heat pump, the coolant should be recovered for disposal at a treatment plant, in accordance with the current regulations.
2.2. HYDRAULIC CIRCUITS
The installation and any further actions on the heating-cooling, brine and DHW circuits should be performed by authorized personnel only and in accordance with applicable local regulations and following the instructions provided in this manual.
DANGER!
Avoid touching the pipes, the compressor or other parts of the heating-cooling, brine and DHW
circuits during or immediately after operating the heat pump. These could be at high or low temperature, and touching them could result in burns from heat or cold. If you need to touch these parts, allow time for temperatures to stabilize and use protective gloves to prevent injuries.

2.3. ELECTRICAL INSTALLATION
Any action carried out on the electrical installation of the equipment should be performed by an authorized installer and in accordance with the applicable local regulations and the instructions outlined in this manual.
3. HEAT PUMP OVERVIEW
3.1. MODEL IDENTIFICATION
The range of ecoGEO heat pumps is available in two models, ecoGEO B and ecoGEO C. The ecoGEO C heat pumps include a built-in DHW tank of 170 litres. The ecoGEO B heat pumps have only the heat pump module and the DHW tank should be installed separately. Each of this models are available in 9 different models, depending on the application, the heating output and the type el power supply, as described in Table 3.1.
ecoGEO B1 and C1 models provide heating and DHW non-simultaneously, using a 3-way valve. In addition, the ecoGEO B2 and C2 models provide passive cooling option, allowing moderate cooling to the housing with a minimum consumption of the heat pump (a consumption resulting from circulation pumps only). ecoGEO B3 and C3 models provide simultaneously DHW and climate control system through cycle reversal. Each one of the three versions is available for adjustable heating outputs within the ranges 3-12 kW and 5­22 kW, given the use of inverter compressors. 3-12 kW models are available only with single-phase power supply, while 5- 22 kW models are available with both single-phase and three-phase power supply.
DANGER!
Before carrying out any operation on the electrical panel, disconnect the power supply. When the upper front cover of the heat pump is removed, the electrical panel is exposed and its
components could be touched accidentally. During the installation and maintenance of the equipment, never leave the electrical panel unsupervised while exposed.
Avoid touching any component of the electrical panel with wet hands; otherwise, electric shocks may
occur.
Avoid touching any electrical component of the heat pump (including circulation pumps, valves,
legionella protection electric heater, etc.) either during or immediately after operating the equipment. Otherwise, fire or electric shocks may occur.
Avoid using water or other liquids for cleaning the heat pump; otherwise, fire or electrical shocks may
occur.

3.2. OPERATING PRINCIPLES
ecoGEO geothermal heat pumps are designed for conditioning (heating and cooling) and providing DHW all­year round with simple installation and guaranteeing maximum energy efficiency at all times.
Installations with geothermal heat pumps consist of three main circuits (refrigerant circuit, brine circuit and heating-cooling circuit), in which thermal energy is carried between the ground and the building by using several fluids (refrigerant, antifreeze mixture and water). These circuits use different fluids; therefore, the transfer of thermal energy from one fluid to another is done by heat exchangers, where fluid at the highest temperature transfers heat to the fluid at the lowest temperature without mixing.

The operating modes provided by the different technologies included in the ecoGEO geothermal heat pumps are outlined below.
HEATING MODE During the normal operating cycle, heat pumps draw energy from the ground for producing hot water in
the heating system. Its operation can be split into four sub-processes which are repeated on a cyclical basis.
The antifreeze mixture is successively circulated by a circulation pump through an ground source system, where it absorbs heat from the ground, and the evaporator, where it transfers heat to the fluid in
1

Page 10
the refrigerant circuit. The refrigerant in the evaporator is at low pressure and temperature, and it vaporizes as a result of the heat absorbed by the antifreeze mixture.
The refrigerant vapour coming from the evaporator is suctioned by the variable-speed inverter compressor, where its pressure and temperature increase (hot gas) in order to meet the actual heating demand.
The hot gas coming from the compressor is led to the condenser, where it transfers heat to the water in the heating system. As a result of this heat transfer, the refrigerant gas cools down and condenses into liquid form.
The refrigerant in liquid state is led back to the evaporator through the electronic expansion valve, which accurately controls the re-circulated refrigerant flow rate based on the heating system requirements. At the same time, while passing through the electronic expansion valve, the pressure and the temperature of the coolant decrease in order to attend again the condition to absorb heat from the antifreeze mixture in the evaporator.
FREE COOLING MODE (ECOGEO B2 AND C2 MODELS ONLY) The heat pump is supplied with an extra heat exchanger which allows direct heat exchange between the brine in the ground source system and the water in the cooling system, so the refrigerant circuit is not used. By using this operating mode, the compressor remains off and the cooling and brine circuits are derived to the free cooling heat exchanger through two 3-way valves. Thus, the equipment supplies fresh water to the cooling system, obtained from the energy exchange with the brine system, all with the sole use of circulation pumps.
This technology allows to air-condition dwelling (or commercial premises) all-year round in temperate regions, where temperatures during warmer months do not reach excessively high values. It is worth mentioning that, in the FREE COOLING mode, energy consumption is very low due to the high efficiency of circulation pumps.
ACTIVE COOLING MODE (ECOGEO B3 AND C3 MODELS ONLY) Active cooling consists of reversing the operating cycle of the heat pump's refrigerant circuit through a 4-
way valve. This means that the normal cycle condenser becomes the reversed cycle evaporator, and vice versa. In this operating mode, the fluid in the cooling system (water) draws heat from the dwelling and transfers it to the refrigerant in the evaporator; whereas the antifreeze mixture absorbs heat from the refrigerant in the condenser and transfers it to the ground. This operating mode is called active cooling by cycle reversing.
This technology provides year-round air-condition for housing (or commercial premises) even in regions where temperatures reach high values during warmer months.
DHW MODE The production of domestic hot water (DHW) is performed by two different technologies, depending on the model. For ecoGEO B1, B2, C1 and C2 models, the production of DHW is done by deviating the hot water from the condenser into the coil of the DHW tank via a 3-way valve. EcoGEO B3 and C3 models are equipped with CHW patented technology (Closed Hot Water production system). This new technology consists of incorporating an additional heat exchanger (desuperheater) intended for DHW production only. This heat exchanger is placed in series with the main condenser and feeds hot water into the coil of the DHW tank through a closed circuit. Also, given the fact that cycle reversal is done after the desuperheater, it allows simultaneous DHW and heating/active cooling production. Therefore, the CHW system can produce DHW up to 45ºC and also heat it up slowly when the machine is working to produce heating, cooling or servicing the pool up to 70ºC.
Page 11
If the electric support is enabled, the electric resistance works only at the end to heat the DHW up to the antilegionela setpoint. Therefore the electric resistance is used as little as possible.
LEGIONELLA PROTECTION MODE The heat pump is equipped with a electric resistance installed in the DHW tank, intended for preventing
potential legionellosis outbreaks only. Once per week, the heat pump increases the storage tank temperature up to the setpoint temperature, and the electric heater is subsequently activated in order to increase the DHW temperature up to 65 ºC, i.e., a temperature at which the bacteria cannot survive more than 20 minutes. It is recommended to carry out the heating during the night, when no DHW is being consumed.
POOL MODE The pool mode allows activating an external 3-way valve for deviating the hot water supply from the heat pump into a heat exchanger through which heat is transferred to the water in the swimming-pool.
FAULT MODE In the event of heat pump failure, that impedes start the compressor, the electric heater can be activated
for daily DHW production, ensuring DHW production for the user in case of heat pump failure.

4.2. PROGRAMS
ECOFOREST ecoGEO heat pumps have three main operating programs, which are described below.
WINTER PROGRAM The heat pump only allows activation of the operating modes HEATING, DHW, LEGIONELLA PROTECTION, POOL and FAULT. FREE COOLING and ACTIVE COOLING operating modes are not permitted.
SUMMER PROGRAM The heat pump only allows activation of the operating modes FREE COOLING, ACTIVE COOLING, DHW, LEGIONELLA PROTECTION, POOL and FAULT. HEATING operating mode is not permitted.
AUTO PROGRAM The heat pump automatically selects one of the WINTER / SUMMER operation programs based on several environmental parameters. In the example in Figure 4.2 if the outside temperature rises above 26 ° C over a period of 5 hours an automatic program to SUMMER WINTER program occurs. If the outside temperature drops below 12 ° C over a period of 5 hours an automatic program to WINTER SUMMER program occurs.
Figure 4.2. Example of AUTO program configuration.
MIX PROGRAM The MIX program does not work with SUMMER/WINTER program. It is designed to produce heating or
cooling, always prioritising the DHW. To produce heating the machine needs relay signals (thermostat signals) at points DI1 and / or DI4 to. To produce cooling the heat pump needs relay signals at points DI3 and / or points DI5.
Note that, to work with the mixed program, the th-tune terminals cannot be used implementing the “buffer tank” scheme. Also you should pay attention to the “heating stop temperature” in for heating and cooling in user menu (see section 4.5 points 1.3, 1.6 and 1.7).
To set the MIX program it is necessary to follow the steps in AUTO program and to set a summer temperature higher than the winter one. The machine will be in MIX program when the outdoor
Page 28
temperature is between the winter and the summer temperature. In addition you must put the time change to 0h.
4.3. OPERATION SHEMES
The ecoGEO heat pump can be connected to the heating-cooling system using three different schemes. The functionality and the menus available from the heat pump control program depend greatly on the type of connection plan used. The main features of each scheme are detailed below. Pump control
1 ZONE SCHEME Installations with the heat pump directly connected to the heating-cooling system supplying one
temperature level (hereinafter referred to as "1 Zone").
2 ZONE SCHEME Installations with the heat pump directly connected to the heating-cooling system supplying two different temperature levels controlled by the heat pump (hereinafter referred to as "2 Zone"). The heat pump supplies directly at the highest outlet temperature (Zone 1). The lowest outlet temperature (Zone 2) is reached by an external shunt group with a modulating mixing valve.
BUFFER TANK SCHEME Installations with the heat pump connected to a intermediate buffer tank between the heat pump and the
heating-cooling system.
4.4. HOME SCREEN
The front panel turns on when the external breaker of the heat pump is activated. While the application is loading, a display with the ECOFOREST logotype opens. After a few seconds, the home screen comes up showing different icons informing about the condition of the pump (operation program, operation mode, date and time, and status). Figure 4.3 shows the home screen and Table 4.1 contains the meanings for the icons that can appear on it.

MENU 1.3. HEATING In this menu you can ENABLE / DISABLE the heating mode. It should also adjust the maximum outside temperature value above which disables.
In 1 ZONE and 2 ZONES schemes the flow setpoint temperatures for each zone are shown. This value is configured in the installer menu, see section 2.2.3.1, with temperature curve or fixed setpoint. If the user wishes to increase or decrease these temperatures should go to the next page "1.3.2 Heating Curve" and fill or empty the bars of the zone concerned. Each section that moves are added or subtracted 2 °C. Initially the bar is at the midpoint can fill two sections (totaling 4 °C) or empty it completely (minus 4ºC).
In the scheme BUFFER TANK setpoint temperature and offset for the tank temperature is displayed. This value is configured in the installer menu, see section 2.2.3.1. If a fixed setpoint was chosen this value is editable in the user menu. If a temperature curve was chosen can be changed using bars as explained in the previous paragraph.
MENU 1.4. DHW/LEGIONELLA
MENU 1.4.1. DHW
It grants to adjust the DHW temperature set point, as well as the offset (temperature difference) below the temperature set point from which the production of DHW is enabled.
If the electrical resistance disables support the "Setpoint - Offset" value must not exceed 45. The difference will be automatically modified to enforce this rule. This is due to the fact that the compressor struggles to start with tank temperatures above 45 ° C.
Page 33
If you have enabled the electrical support the "Setpoint - Offset" value can be higher than 45 ° C but the compressor only start when the tank temperature is below 45C so much of the DHW produced will be resistance.
Furthermore only for B3 and C3 models must be configured CHW value. The high temperature of the compressor discharge can heat the water up to maximum 70ºC. You can configure up to 70 but only produce DHW at this temperature when the machine is working to produce another demand, is heating, cooling or swimming pool.
MENU 1.4.2. LEGIONELLA PROTECTION
It allows to ENABLE/DISABLE the LEGIONELLA PROTECTION mode. It is also possible to set the day of the week and the time at which the LEGIONELLA PROTECTION mode is to start.
MENU 1.5. POOL
MENU 1.5.1. POOL
It permits to ENABLE/DISABLE the POOL mode. It also allows you to set the minutes per hour of winter program. This parameter sets the minutes per hour that the machine works with pool only under the case there is demand for heating and pool at the same time.
In summer mode the cooling has preference over the pool. If we want to establish some kind of preference for the pool we can only limit the operation of the cooling in the cooling schedule as explained in section 1.2.3.4.
MENU 1.6. FREE COOLING This menu is only available in ecoGEO B2 models. It allows ENABLING/DISABLING the FREE COOLING mode. It should also adjust the minimum outside temperature value below which disables.
It also allows setting the free cooling temperature. Keep in mind that if you install terminals th-tune and configure a different system than fan coil, humidity control can take a different setpoint value to avoid condensation.
MENU 1.7. ACTIVE COOLING This menu is only available in models ecoGEO B3 and C3. In it you can ENABLE / DISABLE active cooling completely. It should also adjust the minimum outside temperature value below which disables.
In 1 ZONE and 2 ZONAES schemes the flow setpoint temperature for each zone are shown. Is possible to configure this value in the installer menu, see section 2.2.3.1, using curve or fix temperature setpoint. You can only change these values if the setpoint chosen in the installer menu is fixed.
In the scheme BUFFER TANK the setpoint temperature and the offset are shown. Is possbile to configure this value in the installer menu, see section 2.2.3.1, using curved or fix temperature setpoint. You can only change these values if the setpoint chosen in the installer menu is fixed.

Follow these steps in the indicated order to disassemble the heat pump and place it in its final place of installation.
1. Carefully take the heat pump out of the package (wooden box, plastic, etc.).
2. Carefully take the moorings that fix the heat pump.
3. Check that the heat pump has not been damaged during transportation and that all its components are included.
4. Place the heat pump in its place of installation.
Take into account the recommendations about its transport and location of sections 5.1 to 5.3.
Page 42
5.1. TRANSPORT AND HANDLING
EcoGEO heat pumps must be transported in vertical position in such a way that they are not exposed to inclement weather.
When moving the heat pump to its place of installation, it must be carefully handled. If strictly necessary, the heat pump can be disassembled in two modules for easy transportation and handling.
5.2. RECOMMENDATIONS FOR LOCATION
The heat pump must be installed on a stable base, preferably concrete, which is capable of supporting the total weight indicated in the technical specifications (see section 12.1) as well as the volume of water contained in the DHW tank (170 kg approx.). If the heat pump is installed on an unstable base (for example, wood), this must be reinforced so that it supports the total weight of the equipment.
Before selecting the place of installation of the heat pump, consider the following recommendations.
Choose a dry place where there is no risk of frost. If possible, install the heat pump with the back side towards an exterior wall and in a place where the
noise emissions do not cause a problem. Whenever possible avoid installation against bedrooms or other places where noise emissions may be annoying. Avoid installing the heat pump near a corner, as this may amplify the level of the equipment noise emission.
Check that the heating-cooling, brine, mains water and DHW piping can be installed properly. To
avoid condensation in the piping of the brine circuit, try to minimize as much as possible these sections inside the building and insulate them properly.
Check that there is enough space to carry out the installation and maintenance work of the heat
pump comfortably (see section 5.3).
Once the heat pump is positioned in its final location, it is necessary to level it so that it remains in horizontal position. For this reason, it is fitted with adjustable feet of up 25 mm in height to compensate for possible irregularities of the base surface. Is the irregularities of the base cannot be compensated with the height­adjustable feet; the base must be sufficiently leveled before installing the heat pump.
NOTE
Do not install the heat pump near machines which issue electromagnetic activity, as they may
interfere with the electronic components and make the equipment stop working properly.
NOTE
The heat pump should never be bent more than 45º vertically as this may provoke the malfunctioning
of the equipment.
DANGER!
The heat pump can weigh up to 240 kg net. The device must be handled by, at least, two operators
using a hand truck to avoid personal injuries.
Page 43
5.3. SERVICE AREAS
It is recommended to leave enough space around the heat pump in order to make installation and maintenance work easier. The recommended minimum distances regarding walls and other elements are the following.
300 mm from the sides. 600 mm from the front. 10 mm from the back

6. HYDRAULIC INSTALLATION
6.1. HEATING/COOLING CIRCUIT CONECTION
Inside the heat pump there are included the following components required for the heating-cooling system (see section 3.4).
Variable speed and high efficiency circulation pump (energy class A). Expansion vessel (12 litres). Safety valve (6 bar gauge). Drain valve.
To connect the heating-cooling circuit, consider the information indicated in Figure 6.1 and the following recommendations.
Use the flexible hoses that are included with the heat pump in order to avoid excessive stress in the
inlet and outlet pipes.
Install shut-off valves in the outlet and inlet pipes of the heating-cooling circuits, as close to the heat
pump as possible to facilitate future maintenance work of the heat pump.
Install a strainer in the heating-cooling circuit inlet. Install air vents in all places of the installation where air bubbles may form.
NOTE
EcoGEO B heat pumps must not be used in heating systems with high temperature radiators or in
other appliances which require outlet temperatures of above 55 ºC, which would make the equipment
malfunction. Make sure the pipe connections are not subject to stress as this may cause leaks. The inlet and outlet pipes of the heating/cooling circuit must be insulated thermally to prevent
unnecessary heat losses and avoid risks of freezing the fluid.
DANGER!
Do not install components that may clog the inlet or outlet ports of the safety valve of the
heating/cooling system; there may be risk of breaking some of its components and cause injury
and/or damage to property. When installing the heating/cooling circuit, special care must be taken to avoid getting water on the
electrical panel and this could produce personal injury from electrical shock and/or make the
equipment malfunction.

6.2. DHW TANK CONNECTION
To connect the DHW circuit, take into account the information of Figure 6.2 for ecoGEO B1, B2 and B3 and the Figure 6.3 for ecoGEO C1, C2 and C3.
To facilitate future maintenance work of the heat pump, install shut-off valves in the mains water inlet
and in the DHW outlet.
Install a check valve in the mains water inlet in order to avoid possible hot water returning from the
tank to the main network.
Install a check valve in the DHW coil circuit in order to avoid possible inverse circulation of the water. Install air vents where necessary in the DHW coil circuit in order to avoid possible air bubble
formation.
If necessary, install a security group (expansion vessel + safety valve) in the mains water inlet to
avoid possible overpressures in the DHW tank.
Due to LEGIONELLA PROTECTION mode (see section 3.2) the temperature of water in the DHW
tank may reach 70 ºC. If the installation of the DHW in the place lacks thermostatic taps, it is recommended to install a thermostatic mixing valve in the DHW outlet to avoid risk of scalding.
If the maximum system pressure can exceed 5 bars, it is recommended to install a pressure
reducing valve in the mains water inlet in order to avoid overpressure in the DHW tank.
For a correct operation of the installation, a mains water pressure of at least 2 bars must be
guaranteed in order to obtain a DHW flow rate of at least 20-25 l/min. Remember that the water pressure is reduced during periods of high water consumption. Check that the minimum operating pressure of the installation is ensured under these conditions.
Insulate thermally the DHW outlet pipe in order to prevent unnecessary heat losses.
NOTE
For proper operation of ecoGEO B heat pumps during DHW preparation the coil of the DHW tank
should has a minimum heat transfer area of 2.5 m2. Make sure the pipe connections are not subject to stress as leaks may occur.
DANGER!
Do not install components that may clog the inlet or outlet ports of the safety valve of the DHW tank;
there may be risk of breaking the tank and causing injury and/or damage to property. When installing the DHW circuit, special care must be taken to avoid getting water on the electrical
panel. This could produce personal injury from electrical shock and/or make the equipment
malfunction.

6.3. BRINE CIRCUIT CONNECTION
When brine systems are used with more than one circuit, these must be connected in parallel so that the flow rate circulation through each is similar. The maximum length of all the brine system pipes should not exceed 400 m.
Figure 6.4. Types of brine systems.
In vertical probe systems, it is recommended to use circuits between 80 and 150 m long, with a minimum separation between circuits of 8 meters.
In horizontal collector systems, it is recommended to bury the coil between 1.2 and 2 meters deep and with a separation between tubes of at least 0.8 meters.
The refrigerant evaporation temperature can fall below 0 ºC. For this reason, in brine systems with groundwater, it is recommended to use an intermediate intercooler to prevent freezing problems and fouling in the evaporator of the heat pump.
Horizontal collector
Groundwater system
Vertical probe
NOTE
Insulate thermally the brine circuit pipes in order to prevent condensation and/or frost formation as
the brine circuit pipes may reach temperatures below 0 ºC. Make sure there pipe connections are not subject to stress as this may cause leaks. In brine systems with groundwater, it is recommended to use an intermediate exchanger to avoid
freezing problems and evaporator fouling.
DANGER!
Do not install components that may clog the inlet or outlet ports of the safety valve of the brine
system. There may be risk of breaking some of its components and causing injury and/or damage to
property. When installing the brine circuit, special care must be taken to avoid getting antifreeze mixture on the
electrical panel as this could produce personal injury from electrical shock and/or make the
equipment malfunction.

inlet and outlet pipes.
Install shut-off valves in the outlet and inlet heating-cooling circuits, as close to the heat pump as
possible to facilitate future maintenance work.
Install the necessary components to carry out the filling/emptying of the working fluid in the return
pipe.
Install a expansión vessel and a safety valve with ecoGEO B2 and B3. The ecoGEO B1, C1, C2 and
C3 have an expansión vessel (5 litters) and a safety valve (3 bar) integrated in the heat pump.
Install a strainer in the inlet circuit. It is recommended to install shut-off valves just before and after
the strainer in order to avoid antifreeze mixture losses during cleaning or filter replacement.
Install air vents at all points of the installation where air bubbles may form. Insulate thermally the brine circuit pipe in order to prevent unnecessary heat losses and avoid
condensation problems.

7.8. POOL VALVE
The heat pump allows controlling the activation of an external pump, as well as a 3-way valve to deviate the heating flow to the pool heat exchanger. To that end, it is required a voltage-free signal that informs the heat pump whenever there is demand of heating the pool, generally from a cronothermostat. This signal is directly connected to the micro-controller through the J4 connector, as shown in Figure 7.11 (see also sections 12.3 to 12.5).
In order to make the power installation, follow Figure 7.12 (see also sections 12.3 to 12.5).

8. INDOOR CONTROL DEVICES
Geothermal pumps ecoGEO can be controlled, through th-Tune (with Modbus connection) or through conventional relay type thermostats. With both options, the heat pump allows controlling 1 or 2 different outlet temperatures (hereinafter Zone 1 and Zone 2), depending on the selected operating scheme and installation.
8.1. TH-TUNE INDOOR TERMINALS
ecoGEO geothermal pumps are programmed to be used with Carel th-Tune indoor terminals. These terminals send information about the indoor temperature and humidity of the room. These should be located in the most representative part of each zone, generally in the larger one, for example, in the living room. The heat pump takes de temperatures registered by the th-Tune terminals as reference in order to make a precise control of the indoor temperature.
To install the th-Tune terminal, it is necessary to connect the power supply and the RS485 serial cable. Before installing, take into account the following recommendations.

NOTE
In order to get the best indoor comfort services and optimize the energy efficiency of the heat pump,
it is recommended to make an indoor control through indoor th-Tune terminals.
The activation signals of the heat pump, control with thermostats and the pool control (DI1 to DI6
inputs) must be voltage-free contacts.
Page 61
1. Before connecting the power supply terminal, carefully read the instructions included in the Th-Tune manual. Check that the supply voltage is correct. There are models with 24 Vac/Vdc and 230 Vac.
2. To connect the RS485 serial port use AWG type 20-22 two-pole shielded cable. For cable lengths exceeding 500 m, it is necessary to install a 120 Ohm resistance between Rx+/Tx+ and Rx-/Tx- in the first terminal and in the last one in order to prevent possible communication problems. For more information, see the Th-Tune manual.
The RS485 serial cable connection is made directly to the card installed in the micro-controller BMS connector, as shown in Figure 8.1 (see also sections 12.3 to 12.5). 1 or 2 terminals can be connected depending on the fact of how many different outlet temperatures are controlled (1 or 2).

8.2. CONVENTIONAL RELAY THERMOSTATS
ECOFOREST geothermal pumps can be controlled through one or various conventional relay thermostats, allowing the switching on/off of the heat pump according to heating demand of the house. For this reason, it has 4 digital independent inputs, 2 dedicated to the heating demand of each of the zones with different outlet temperature, and 2 dedicated to the cooling demand in each of the zones with different outlet temperature (only in models ecoGEO B2 and B3). Each of these control signals derives from one or various thermostats. If more than one thermostat is used per signal, these must be connected in parallel in such a way that if only one of them is active, this can be detected by the heat pump. The input signals are connected directly to the micro-controller through the J4 connector, as per 8.2 (see also sections 12.3 to 12.5).

9. FILLING THE CIRCUITS
Before configuring and starting up the equipment, it is necessary to fill, purge and pressurize properly all the circuits of the heat pump. In order to do that, follow the steps of the following sections.
9.1. FILLING THE HEATING/COOLING CIRCUIT
To fill the heating-cooling circuit, use water only. Before starting the heat pump, make sure the air contained in the heating-cooling circuit has been completely purged, its pressure is suitable and there are no leaks in the circuit.
In order to facilitate the filling of the heating-cooling circuit, it may be convenient to activate the heating pump. In order to do so, access INSTALLER MENU -> CONFIGURATION -> ACT. MANUAL COMPO. -> HEATING/COOLING PUMP -> State, switch value to ON.
To drain the heating-cooling circuit completely, the heat pump has a drain valve at the lowest part of the circuit, just under the heating-cooling circulation pump (see section 3.4).
9.2. FILLING THE DHW COIL CIRCUIT
The circuit of the DHW external buffer coil is connected to the climate control circuit. For this reason, the filling of this circuit must be simultaneously accomplished with the filling of the climate control circuit. To do it,
NOTE
Do not add anti-corrosion or anti-freezing additives to water in the DHW buffer coil circuit. Joints or
other components may be damaged a leak provoked.
DANGER!
During the process of filling the DHW circuit, be very careful that water does not drop on the electrical
board. It may cause personal injury due to electrocution and/or provoke the equipment malfunction.
NOTE
Do not add antifreeze or anti-corrosion additives to the heating/cooling system fluid as this may
damage the seals and other components and cause leaking.
Before filling the heating/cooling circuit, it is convenient to carry out the electrical installation so that
the heating/cooling circuit pump can be used.
DANGER!
During the filling of the heating/cooling circuits, special care must be taken to avoid getting water on
the electrical panel as this could produce personal injury from electrical shock and/or make the equipment malfunction.
Page 64
open the manual or automatic deaerators which are installed in the circuit that connects the heat pump to the DHW buffer coil until be sure that the circuit is completely empty of air.

If the above mentioned process does not guarantee that the circuit is completely empty of air, you may need to activate manually the circulator pump of the coil circuit. In ecoGEO B1 and B2 models, activate manually on several occasions the 2 way climate control/DHW valve (INSTALLER MENU-> CONFIGURATION -> MANUAL TEST -> DHW VALVE -> State, change value to ON) while the heating-cooling circulator pump is activated until being sure of a proper deaeration of the coil. In ecoGEO B3 models activate manually the DHW circulator pump (INSTALLER MENU-> CONFIGURATION -> MANUAL TEST-> DHW PUMP -> State, change value to ON).
In ecoGEO B1 and B2 models, the circuit emptying of the buffer coil is accomplished together with the heating-cooling circuit through the emptying valve placed below the heating-cooling pump (see section 3.4).
To empty the circuit of the buffer coil in ecoGEO B3 models, use the valve placed just below the DHW circulator pump (see section 3.4).
Page 65
9.3. FILLING THE BRINE CIRCUIT
The brine system temperature may drop below 0 ºC, so a mixture of water antifreeze with a freezing point around -17 ± 2 ºC should be used. It is recommended to use a propylene glycol antifreeze (max. 33% by volume) or ethylene glycol (max. 30% by volume) with corrosion inhibitor.
The estimated volume of the antifreeze mixture required to fill the brine circuit must be calculated taking into account the following.
Heat pumps (exchangers + pipes + expansion vessel, 5 litres). Brine pipe per lineal meter. It is not recommended to use pipes with diameters lower than those
shown in Table 9.1 as the high speeds of circulation of liquid may cause noise and corrosion problems.

Filling the brine circuit must be done through an external filling pump, as indicated in Figure 9.2, following these steps.
1. Prepare the antifreeze mixture in properly concentration in the external tank (11).
2. Connect the outlet port of the filling pump (10) to the filling valve C (9).
3. Connect a transparent hose from the filling valve B (8) to the external antifreeze tank so that its end is immersed.
4. Close the filling valve A (7).
5. Open the filling valves B and C.
6. Activate the external filling pump to fill the circuit.
7. Activate in manual mode the brine circuit pump (INSTALLER MENU -> CONFIGURATION -> MANUAL TEST -> BRINE PUMP -> State, switch the value to ON) in order to facilitate the circulation of the antifreeze mixture through the circuit.
8. Keep the external filling pump and the brine pump running until no air bubbles are seen in the fluid that goes through the transparent hose to the antifreeze mixture tank.
NOTE
Before filling the brine circuit, it is necessary to complete the electrical installation so that the brine
pump can be activated.
Check the local regulations before using any kind of antifreeze mixture.
DANGER!
During the filling of the brine circuit, special care must be taken to avoid getting antifreeze mixture on
the electrical panel as it may cause personal injury from electric shock and/or cause equipment malfunction.
Page 66
9. Deactivate in manual mode the brine circuit pump (INSTALLER MENU -> CONFIGURATION -> MANUAL TEST -> BRINE PUMP -> State, switch the value to OFF).
10. Open the filling valve A, maintaining the external filling pump connected in order to eliminate the air contained between filling valves B and C.
11. Close the filling valve B and pressurize the brine circuit up to the service pressure through the filling pump.
12. Close the filling valve C.
13. Disconnect the external filling pump and the rest of the filling components.

10.13. FINAL INSPECTION AND START UP OF THE INSTALLATION
Before initial operation, check the following points in order to ensure that it have been completed successfully.
CHECKING THE HEATING-COOLING, BRINE AND DHW CIRCUITS
1. The heating-cooling installation was performed according to Figure 6.1, including all components.
2. The DHW installation was performed according to Figure 6.2, including all components.
3. The brine installation was performed according to Figure 6.5, including all components.
4. Flow and return pipes from different circuits have been isolated properly.
5. The heating-cooling and brine circuits have been filled, aerated and pressurized properly.
6. The installation has been checked in order to detect fluids leak.
CHECKING THE ELECTRIC INSTALLATION.
1. The heat pump’s power supply installation has been performed according to Figure 7.3 in single­phase models and Figure 7.4 in three-phase models.
2. The electric installation includes an external switch that cuts all circuits.
3. The inside ambient terminals have been correctly positioned and installed.
4. The outside temperature probe has been correctly positioned and installed.
5. The buffer tank temperature probe has been correctly installed (only in installations with intermediate buffer tank).
NOTE
The initial operation should only be done once after checking the heating-cooling, brine and DHW
circuits have been filled and aerated properly.
Note that if during the operation of the installation, any alarm is activated, may be due to a faulty
bleeding of the circuits.
EcoGEO heat pumps have a program to conduct the floor drying in under-floor installations (see
section 4.6).
Page 78
6. The external shunt group has been correctly installed (only in installations with external shunt group for the second outlet temperature controlled by the heat pump).
OPERATION AND INSPECTION OF ABNORMAL NOISES
1. Check the equipment for abnormal noises that indicate possible damages to some components during transport or installation. It is necessary to verify the heat pump in all operating modes (heating production, DHW and active cooling or free cooling where applicable) to ensure that there is no any abnormal noise.
2. Check as well any abnormal noises elsewhere in the installation.
Page 79
11. IDENTIFYING PROBLEMS AND TROUBLESHOOTING
11.1. ALARM LIST
There are a number of parameters that the heat pump monitors at all moments to verify proper operation of the equipment. If any of these parameters are not within the standard, an alarm is activated to inform the user that there is an abnormal operation of the heat pump. If any alarms are active, the button [Alarm] on the front panel lights up in red and, if you press this button, you can access to the alarm menu (see section 4.5, menu 1.9).
If the cause of the alarm is solved, this one disappears automatically. There are some alarms which if repeated five times consecutive; a permanent alarm is activated, so that the heat pump cannot start until the permanent alarm is erased manually.
