4.4 ECOWAY: Other functions / running in the background
4.4.1. Dry stop function - protects the heating element against damage as a result of the lack of water
in the tank. Please note, that you can never switch on a tank that holds no water. In that case the Dry
stop function will not prevent damage. The function is activated at any time when the heater starts
working and lasts for 1.5 min. and may not be stopped. At this time, the HEATER LED will continue to
be lit even if we change the program or temperature setting.
4.4.2. Anti-freezing function - is activated when the controller is off (only the power LED is lit). It
prevents the water in the tank from freezing by turning on the electrical heating element.
4.4.3. Anti-legionella function
– Operates automatically. Every 14 days, the controller heats the water
in the tank to 75°C to disinfect the tank surface and eliminate any possibly present legionella
bacteria,
4.4.4. Temperature limiter function - prevents overheating of the water in the tank - In case the water
temperature increases excessively, the electricity supply to the heating element is disconnected at
both poles.
4.4.5. Hysteresis function - the controller turns on the heating element when the water temperature
drops by 2°C below the set temp., which allows for lowering the number of switching cycles and
increases the service life of the heating element and the controller components.
4.4.6. Clock - displays the programmed time in the controller; to display the clock, press OK.
4.4.7. Active protection - a set of relays which disconnects the electric heating element on two poles,
which increases the safety of work of the heater by eliminating the possible risk of electric shock.
4.5. ECOWAY: Error codes
Er01 - the temperature limiter was triggered - exceeding the permissible water temp. inside the tank.
Before re-connect the heater, it is necessary to remove the plug from the socket for at least 5 minutes
and wait till the water temperature drops.
Er02 - the driver has detected the lack of water in the tank. To clear the error, press OK. That switches
the driver off and will cut of the power to the heater for 20 minutes and then resume normal operation.
In the case of frequent Er01 messages and the fluctuation of water temp at the tank supply, it is
recommended to turn the detection of the lack of water from the service menu - item 7.7.
AL or AH - damage to the temperature sensor or a decrease in temperature below 0 °C or rise above
99°C, it is necessary to call your supplier to replace the sensor.
4.6 ECOWAY: Service menu
To navigate to the service menu, it is necessary to turn the driver off (the POWER LED is lit), and then
hold the PROG button. The display will show Fx yy (yy flashing) where x is the number of the
parameter and yy is its value. Use the up / down keys to change the value, and OK to confirm and
move to another parameter; after editing the last parameter (6), the driver will exit the service menu.
Each entry to the service menu causes the reset of the ECO+ function and restarts learning.
