Programming T1, T2, T3 buttons
The heater can save three values of temperatures selected by the user. To save, as well as
select temperatures the buttons marked T1, T2, T3 are used. In order to assign the tempera-
ture value to any of the buttons (T1, T2, T3):
1. Set the desired temperature on the display by pressing “–” or “ + ”
2. Hold down any of the selected buttons ( T1, T2, T3) for approx. 4 seconds till the moment
when the digits on the display will go out for a moment signalizing by that that the value
of the temperature set on the display has been assigned to the memory of the pressed
button.
After short pressing of any of the buttons (T1, T2, T3), the programmed temperature will be
displayed, and thereby the set temperature with which the heater is to heat the water. In order
to re-program any of the buttons (T1, T2, T3), follow the instructions given in points 1 and 2.
Display service mode
The simultaneous pressing of buttons marked “–” and “ + ” for about 1 second will make the
display shift from the basic mode (the information about the set temperature and power is
displayed) to the service mode enabling to show such data as:
– flow rate
– inlet water temperature
– outlet water temperature
– installed power
– staring additional sensors (air lock sensors)
In the service mode the display shows different data for approx. 3 separating them by shortly
displaying “0.0”. After displaying the last piece of data, the display automatically shifts to the
basic mode
