Table 13. Temperature setpoint configuration
SETPOINT_STEP: allows to set a temperature's setpoint step value. If the setpoint is
changed locally from the panel (using -/+ buttons), a single press of a button causes a
setpoint change with the step value stored in this register. The setpoint can be changed
in the range determined by setpoint limits stored in the SETPOINT_LOW_LIMIT and
SETPOINT_HIGH_LIMIT parameters.
The setpoint's step value is also automatically adjusted to the setpoint display precision. If
the bit 4 of the SETPOINT_CONFIGURATION register is true, the setpoint value is
displayed with one decimal place. In such case, the setpoint's step value is also adjusted
to one decimal place. The register contains a value multiplied by 10. The default value is
10 (1

C);

How to Change the Temperature Setpoint on the Touchscreen?
Short press + or - button to enter an edit mode (display should start blinking with
a current value);
Change the temperature setpoint value by steps set in the SETPOINT_STEP:
- button decreases the value (multiple times for long press);
+ button increases the value (multiple times for long press).
Reaching a limit value will be signaled with a double beep.
Device will automatically exit the edit mode after the time set in the
EXIT_EDIT_TIME expires from a last interaction.
