INTRODUCTION

Emix Tank is an innovative indoor unit, able to provide domestic hot water from a thermodynamic source all year round,

i.e. independently of the system’s operating mode.

The purpose of Emix Tank is to produce domestic hot water through storage, using the energy produced directly from the

heat pump (therefore renewable energy) and providing the service at the same time as heating and cooling the environ-

ments.

Emix Tank 200 & 300 liters

Emix Tank 200 and 300 liters offers you a complete solution, including:

• The Emix concepts and components.

• A tank of 200 or 300 liters made in steel with porcelainized coating.

• A solar coil in Fe P195GH to be connected to a third parts solar panel system.

• Two per 1 kW electric elements managed by the electronics of Emix Tank.

• A thermostatic mixing valve to manage properly the hot water temperature.

Emix Tank is both a proper heat pump tank and a full feature electrical water heater.

Emix Tank is connected to the proper EMIX port of the heat pump (except outdoor units G30 and G42 where it can be

connected to a normal port, using the adapter from 3/8” to 1/4” for the liquid return  are, included with the outdoor unit).

Further informations in the paragraph “ Only DHW application”.

Anyway, in case of outdoor unit failure, you can use Emix Tank as electrical water heater without the heat pump.

In addition to this, it is required:

• an expansion vessel (MINIMUM 18 l)

• a 3/4” water  lter to be installed upstream of

Emix Tank tap water connection

• inlet and outlet service valves for Emix Tank

• a pressure reducing valve (check hydraulic dia-

grams).

The following diagram illustrates the concept exposed above and shows a system con guration where three indoor direct

expansion units, a hydrokit for a  oor system and an Emix Tank coexist, all connected to a G110.

Emix Tank must be connected to an outdoor unit compatible with Emix.

For speci c models see catalogue.(*)

(*) The models WITHOUT EMIX PORT can not support this new device for the production of domestic hot water.

This manual will use some models abbreviations of compatible outdoor units of the catalogue (Example G30 means

AEI1G30EMX-GR9FI30).

Emix Tank always works in heating mode even when the heat pump is working for cooling of the environments; during

this operation mode, Emix Tank is able to recover the heat which would otherwise be lost in the outdoor air, signi cantly

increasing the energy ef ciency of the entire system.

There are several possible con gurations with Emix Tank and the one represented in the previous  gure is just one of

many.

MODELS COMBINATION

Refrigerant Circuit

Emix Tank is a component that may be connected with other indoor units at the same time by using the special connec-

tion for Emix and duly considering the length of the Emix Tank pipe to be added to the total length set by the outdoor unit

(we advise a speci c insulation of the Emix Tank pipes to guarantee the minimum dispersion of energy).

FOR TUBING LENGTH AND ELEVATION DIFFERENCE LIMIT SEE INSTALLATION INSTRUCTIONS OF OUTDOOR UNIT.

CONSIDER EMIX TANK AS AN INDOOR UNIT OF THE SYSTEM.

FOR THE BEST PERFORMANCE, KEEP EMIX TANK TUBING AS SHORT AS POSSIBLE (MAX. 10m).

TUBING LENGTH AND ELEVATION DIFFERENCE LIMITS

Example n° 1

• Outdoor unit: G80

• Number of indoor units: 4 size A

• Total indoor unit tubing length: 30 meters

• Emix Tank tubing length: 5 meters

• Total tubing length (including Emix Tank): 35 meters

G80 limit (in application 4 units), without additional load, is 40 meters. The system is ok.

Example n° 2

• Outdoor unit: G80

• Number of indoor units: 4 size A

• Total indoor unit tubing length: 50 meters

• Emix Tank tubing length: 7 meters

• Total tubing length (including Emix Tank): 57 meters

EMIX TANK CONFIGURATION

When Emix Tank is on, you can change the setting of some parameters.

To enter the con guration menu, press and hold the BUTTON until the BLUE, YELLOW and RED LEDs light up contem-

porary. At this point release the BUTTON.

After 5 seconds without any operation, Emix Tank exits the con guration procedure and returns to the previous menu.

Booster mode setting

The use of electrical heating elements installed in the storage tank allows you to heat the cold water faster and to reach

the desired water temperature even in conditions of very low external temperatures.

When you activate the Booster mode, the software will automatically handle the electrical heaters.

If after 120‘ from start up of the system the water setpoint is not reached, the  rst electrical element is automatically

activated. The second element will be activated after 120‘ following the course of the water temperature, until reaching

the setpoint.

To activate / deactivate the Booster mode, enter the con guration menu, then quickly press the BUTTON until the only

BLUE LED is  ashing.

Then wait a few seconds until all the 5 GREEN LEDs light up and press the BUTTON once more.

3 consecutive beeps con rm the setting.

If the button is not pressed, after a few seconds the display will return to the main menu without making any setting.

Setpoint limit setting with Heat Pump

It is possible to set the maximum achievable setpoint only with the Heat Pump. This limit can be set to 50°C or 58°C.

To change the setting, enter the con guration menu, then quickly press the BUTTON until the BLUE and YELLOW LEDs

are  ashing.

Then wait a few seconds until all the 5 GREEN LEDs light up and press the BUTTON once more.

3 consecutive beeps con rm the setting.

If the button is not pressed, after a few seconds the display will return to the main menu without making any setting.

NOTE

By default the limit is set to 50°C. We recommend to keep this setting to optimize the energy ef ciency of Emix Tank.

Antilegionella cycle setting

To activate / deactivate the Antilegionella cycle, enter the con guration menu, then quickly press the BUTTON until the

only YELLOW LED is  ashing.

Then wait a few seconds until all the 5 GREEN LEDs light up and press the BUTTON once more.

3 consecutive beeps con rm the setting.

If the button is not pressed, after a few seconds the display will return to the main menu without making any setting.

NOTE

By default, the Antilegionella cycle is on. If the cycle is turned off, the MANUFACTURER can not be held responsible.

For details on the operation of the Antilegionella cycle, see section “ANTILEGIONELLA CYCLE”.

Temperature delta setting for restart of the heat pump

When the water temperature reaches the set value or the maximum achievable value with the heat pump alone (in the

case of Emix Tank operation without other indoor units), the heat pump switches off and starts up again only when the

water temperature drops below the desired temperature of a certain value (delta).

You can change the startup delta of the heat pump by setting it to 5°C or 10°C.

To change the set value, enter the con guration menu, then quickly press the BUTTON until the BLUE and RED LEDs

are  ashing.

Then wait a few seconds until all the 5 GREEN LEDs light up and press the BUTTON once more.

3 consecutive beeps con rm the setting.

If the button is not pressed, after a few seconds the display will return to the main menu without making any setting.

NOTE

By default the startup delta of the heat pump is set to 10°C. We recommend to keep this setting to optimize the energy

ef ciency of Emix Tank.

Reset of the factory settings

To reset all the factory settings, enter the con guration menu, then quickly press the BUTTON until the BLUE, YELLOW

and RED LEDs are  ashing.

Then wait a few seconds until all the 5 GREEN LEDs light up and press the BUTTON once more.

3 consecutive beeps con rm the reset of factory settings.

If the button is not pressed, after a few seconds the display will return to the main menu without making any setting.

Stratiﬁ cation sensor selection

Emix Tank measures the water temperature in the tank through one of the two strati cation sensors.

It is possible to select which of the two sensors is read for the measurement.

To change the sensor, enter the con guration menu, then quickly press the BUTTON until the YELLOW and RED LEDs

are  ashing.

Then wait a few seconds until all the 5 GREEN LEDs light up and press the BUTTON once more.

3 consecutive beeps con rm the setting.

If the button is not pressed, after a few seconds the display will return to the main menu without making any setting.

NOTE

By default the selected strati cation sensor is the upper one.

In addition to the already described modes in the section “EMIX TANK CONFIGURATION”, Emix Tank software can auto-

matically manage electrical back up heaters under certain conditions. This mean that these operation modes are not to

be set and that can not be deactivated. They are:

- Antifreeze mode

- Cold draft prevention mode

- Electrical water heater mode (in case heat pump is not active)

- Antilegionella cycle

Electrical back up heater management – Antifreeze mode

If water temperature inside the tank is lower than 5° C, all electrical elements are switched on until the water temperature

reaches 10° C.

Electrical back up heater management – Cold draft prevention mode

When one or more indoor units are in cold draft prevention mode and compressor is operating since 20’, one by one

electrical element are switched on every 20’; they will be switched off one by one when no indoor unit will be any more

in Cold draft prevention mode.

Electrical back up heater management – Electric water heater mode

If the outdoor unit is stopped for maintenance, Emix Tank will control automatically the electrical heater elements located

inside the tank, exactly like any electrical water heater. In this case, if the water temperature is lower than the desired

temperature for more than 10’, all the electrical heaters will switch on up to the reaching of the setpoint. The end user can

switch off Emix Tank if he does not want to utilise this option.

Electrical back up heater management – Antilegionella cycle

During the Antilegionella cycle, one or more electrical heaters may be automatically switched on. See section “ANTILE-

GIONELLA CYCLE”.

OPERATION OF THE ELECTRICAL HEATER ELEMENTS

Legionella is a bacteria that under certain conditions can be present in any water system.

The proliferation of this bacteria depends on many factors and it  nds the best conditions to survive between 20ºC to

45ºC. That’s why, even though each Country has a different local regulation about Legionella prevention, all of them re-

quire to heat water over than 50ºC.

Anti legionella cycle is a special operation mode performed by Emix Tank. The goal of this mode is to heat the water of

the tank. In this way, all bacteria that may have been inside the water would be killed.

The antilegionella cycle is closed when:

• the water temperature is above 65°C, or

• the water temperature is above 50°C for a variable period of time depending on the temperature itself.

If within 72 hours (3 days) none of the above conditions have been satis ed, the cycle is activated.

During the cycle the YELLOW LED lights up.

It is possible that the electrical heaters are activated during anti legionella cycle.

During the cycle, by water temperature trend analysis, if the software understands that there is not enough energy us-

ing only the heat pump, the  rst electrical heater will be switched on automatically. The second electrical heater will be

switched on after 120’ depending on the water temperature trend up to reach the necessary conditions to close the cy-

cle. If there is a  ow switch connected, the cycle time will be reduced according to the amount of fresh water introduced

into the tank.

If after 8 hours none of the above conditions occurred, the cycle will continue, but the YELLOW LED will begin  ashing

with low frequency to alert the end user.

NOTE: The antilegionella cycle is fundamental for the health of people; it is normally completed due to thermodynamic

energy, however, we can not exclude that in unfavorable atmospheric conditions, the heat pump is unable to complete by

itself the cycle. For this reason it is obligatory to use the heater / the heaters. In case you disconnect the electrical heat-

ers, under certain operating conditions, it may happen that the legionella cycle will not be closed, a condition for which

our company does not assume any responsibility.
