Key Operation
Press the Heating / Cooling key for about 2 seconds to switch between heating and
cooling operating modes; the selection is shown by 2 heating on or cooling on symbols
that will light up .
In heating, the symbol is alight when the setpoint is higher than the room temperature,
both are switched off when the setpoint is lower .
In cooling, the symbol is alight when the setpoint is lower than the room temperature,
both are switched off when the setpoint is higher .
If one of the 2 symbols flashes it means that the water temperature (hot or cold) is not met and it makes the fan stop
until the water reaches the requested temperature. If after powering the device the board detects the H2 probe, the
start-up will take place under normal conditions with minimum and maximum thresholds . The board can also operate
without a H2 probe, case in which the fan stop thresholds will be ignored.

values 5 °C, ma sono consentiti anche i valori fuori scala di 5 °C and 40 °C (except when in auto mode) .
