1Introduction
1.1 Refrigeration gas
The refrigeration gas used in the Eco system is R134a. This is CFC free, is non-inflammable and
does not harm the ozone layer;
•The system comes preloaded with the required refrigerant gas. No additional gas should
be required for the installation.
•Legally, in New Zealand the refrigerant in this system cannot be released into the
environment.
•Handling of the refrigerant must be carried out by an approved refrigeration technician.

2. Hot Water Cylinder
The Eco cylinder is made either of carbon steel with enamel coating or of stainless steel. The
thermal insulation is of expanded polyurethane with a thickness of 50 mm.
The hot water cylinder has a cold water inlet, hot water outlet, recirculation port and an outlet for
the TPR valve. It also comes equipped with a magnesium anode, either in the center at the top, or
at the rear, under the TPR valve port.
There is, in the central part of the hot water cylinder, a flanged opening for the support electrical
resistance (immersion heater) as well as safety thermostat and temperature probe.

valve may have been angled to allow access to the anode for inspection. There may still be a plug at
the top, so the anode can be used in either location.

3. System Operation
3.1 Start-up of the System
Before starting the Eco system, check that the entire installation is set up according to the
recommendations in the complete installation manual then you may plug your equipment to
the power supply.
After switching on your equipment, you should wait a few seconds until the controller starts.
Then follow these instructions:
Notes
•When the compressor is started, the small C under the ECO will come on, and the larger C will start to flash. There is a start
delay on the compressor will start after a delay (the default is 2 minutes).
•The bars on the lower right corner indicate the water temp. Note that 4 bars will show at 55°C. 5 bars only show when the
water is at 65°C (disinfect mode)
•Note: If the ON/Off light is flashing, the system is in Standby. The compressor and E heater are not turned on. You will not
get hot water in this mode.

3.2 Control panel
The control panel of the Thermodynamic Solar system Eco is simple and intelligent. It allows you to
configure several operating parameters according to the operating mode you select.
It comprises six command keys (ON / OFF / CANCEL, MENU, COMP ▲, E-HEATER ▼, DISINFECT and
OK / LOCK) which allow you to monitor and change settings.

3.5 Operating Modes
The Eco system is programmed to work in 3 running modes, ECO, AUTO and BOOST, which are
summarized in this table:
Note that the electrical heater is sometimes referred to as “Immersion heater”, or
“Resistance” in the Eco system.
ECO Operating Mode
In ECO operating mode, the equipment runs only as a Thermodynamic System to heat the
water in the hot water cylinder maximising savings for the user.
If required, the electrical heater (immersion heater) may be activated by manually pressing the
key (E-HEATER). The system will automatically change operating mode to BOOST and indicates
the reason of its activation. If you manually switch off the E heater, the equipment will revert
to ECO mode.
AUTO Operating Mode
In AUTO operating mode, the equipment will run as a Thermodynamic System and/or
electrical heater, (emersion heater) and the operation of the electrical heater is managed in an
optimized way to keep the water hot.
The electrical heater will start every time:
•The user activates it manually (key E- Heater).
•The contact LP opens (low external temperature, lack of fluid, leak in the circuit, etc.).
•The compressor running time exceeds parameter T05*
•The water temperature is below P08*
* Parameters T05 and P08 are adjustable and can be turned ON and OFF
BOOST Operating Mode
In BOOST operating mode, the equipment runs as a Thermodynamic System + electrical
heater, (emersion heater) simultaneously.
This mode enables the user to obtain hot water more quickly.
Once the panel is unlocked (pressure the OK button), the user can change the
operating mode when he/she wishes; he/she need only press simultaneously the
keys MENU + OK/LOCK for 3 seconds and select the mode that suits users’ needs
with the cursor.
After changing modes, check that the compressor is turned on.

TAEC Eco Owners Manual v2.5

15
The Eco comes set by default to work in the “ECO” operating mode. If the user wishes to alter the
operating mode, he/she must follow these procedures:
3.6 Menu parameters
Every time it becomes necessary to alter the settings, the user must access the Menu
The OK key must first be pressed to unlock the system
To access the menu, the key MENU must be pressed for 3 seconds.
After accessing, use the keys COMP ▲and E-HEATER ▼to navigate the menus and submenus.
In order to confirm values / parameters press the key OK/LOCK.
Press the key CANCEL to exit the menu.

3.8 Disinfect Function
Eco’s electronic control features aDisinfect function, which consists of a water heating cycle
increasing the temperature to a higher temperature for a period long enough to prevent the
formation of germs inside the tank. The Disinfect function can be set automatically or manually.
The NZ Building Code G12 regulation regarding protection of hot water storage from Legionella is
daily to greater 60°C, or weekly to greater than 60°C for 1 hour).
The installer must set the disinfect function to at least weekly as required by NZ Building Code. The
Set point should be set to at least 62°C when using the weekly function.
When automatic mode is not activated, the user must activate it manually on the key Disinfect.
At the end of the function, when the temperature reaches the Disinfect setpoint the system returns
to the original operating mode.
The Disinfect function is activated:
•When you press the “DISINFECT” key for 3 seconds
•On the penultimate day of the holiday period (see section 9.7). During the holidays the
value attributed to the parameter disinfect must be nil)
•Automatically when the desired time period is set in the function disinfect
The disinfect function is cancelled when you press the CANCEL (ON/OFF) or DISINFECT keys
The NZ building code requires the temperature to be raised
daily to >60°C daily, or weekly to >60°C for one-hour.
It is recommended that the installer sets the disinfect function
to weekly with a set point of 65°C
3.9 Holidays Function
To activate the Holiday function you need to access the menu and set the number of days you will
be on holiday, and your equipment will automatically enter Standby mode until the last day of
holidays. On the last day, the equipment will begin the Disinfect function to eliminate any
formation of germs that appeared in the hot water cylinder during the time you were away. After
the holidays and once the program Disinfect is over, the equipment will resume the previous mode
selected (ECO, AUTO or BOOST).
If you set your equipment to Holiday mode DO NOT turn it off
with the key ON/OFF,or the function will become inactive.
If you do switch it OFF, or you come home early when you return from
your holidays you must remember to switch on your equipment and
cancel the days of holidays introduced (set the value to 0).
If you do not set the value to 0, your equipment will not restart
until the days of holidays selected have expired.

TAEC Eco Owners Manual v2.5
www.taec.co.nz
18
3.10 PV Function
The PV function enables the possibility of reaching higher water temperatures when an alternative
electric energy source is available (solar PV, wind, hydro) increasing the efficiency of the
thermodynamic solar system and maximising the alternative electric energy source.
Connect a wire from the PV inverter to the
control board of the equipment. This
connection on the control board must be
done to the terminals 5V/P2. Be careful
that this is a dry contact (without power).
Applying power to this contact may cause
irreversible damage to the equipment.
When the contact K1 closes, it activates the
PV function and all the heat sources (both
thermodynamic and electric heater) will be
adjusted to the new working parameters.
The compressor assumes parameters P01PV
/ H01PV and the electric heater assumes
P02PV / H02PV.
Note: When the contact K1 is open, the equipment will assume the previous working mode (Eco,
Auto or Boost) and its previous parameters.
The K1 contact may also be used to take advantage of tariff with variable price. To do that, just
connect a timer to the 5V / P2 contacts instead of an inverter.
