On Leva Multiboiler machines the temperature of each group boiler can be programmed and adjusted
individually via the digital temperature adjusting system.
The temperature control is performed by a PID thermostat, which provides accurate and stable
temperature management for the group.
During normal mode, the temperature display shows
the current temperature of the group boiler. When
the boiler’s heating element is working and water is
heating up, a small blue dot will illuminate to indicate this
function.
Note:
Adjust the group boiler’s temperature up with the
button and down with
button.
To turn the thermostat and its group boiler off, press and hold
the
button for 2 seconds. The thermostat selected will be
disconnected, “OFF” will be displayed, and the group will start to
cool down.

current temperature will be displayed as the group boiler
starts to heat up.

• Press and hold the
button until the temperature display
shows “PrG”.
