3. USER INTERFACE
The front panel contains the display and keyboard, made up from 4 keys, which, pressed individually
or together, allow to perform all of the controller programming operations.
3.1 Display
The display features 3 digits, with the display of the decimal point between -99.9 and 99.9. Outside of this range of measurement, the value is
automatically displayed without the decimal (even if internally the unit still operates considering the decimal part). In normal operation, the value
displayed corresponds to the temperature read by probe B1, that is, the evaporator water inlet temperature*. During the programming it shows the
codes of the parameters and their value.
(*) Viewing of the standard display can be changed via parameter b00.

3.3 Example: timer reset
Pressing e simultaneously, in the timer value display phase (e.g. parameter c10), resets the same at
zero and consequently cancels the maintenance request.
3.4 Programming
The parameters divide into 4 different levels according to their accessibility by the user via password and their function. Entering a certain level it is possible:
1. to access all parameters of the same level and the lower levels (S-P menu);
2. set the desired level for each parameter (L-P menu).
