PUTTING IT INTO SERVICE
• setpoint
• the external temperature measured by sensor T4
• input status
the electronic board makes all the necessary temperature
adjustments to satisfy the heating/cooling or not water pro-
duction needs by operating on the relays and (by means of
PLL logic) on the external condenser signal.
Hot water production, which has higher priority over the
other adjustments, sets heat pump operation of the exter-nal
unit until the desired setpoint is reached (default setting
45°C, adjustable between 30 and 50°C) and simultaneously
activates the three-way valve in order to divert the hot water
produced in the boiler.
This adjustment is indicated by the switching on of the ap-
propriate LED
This function can be disabled by the Technical Service Centre
and in this case the system sensor (T1) will appear automat-
ically on the display, and the hot water sensor (T3) will be
ignored.
The cooling function
is enabled:
• by the closing of the ON/OFF
• of the thermostatic contact TA

The key sets the production of cold water to exploit the
inverter adjustment modulation to the maximum by means
of a PLL logic which acts according to the actual different be-

Stand-by
Standby state can be set using the touch screen interface or
by opening the ON/OFF selection contact connected to ter-
minals 7 – 8.
The display shows OFF, deactivating all settings.
While in stand-by, the device runs an antifreeze cycle
which activates the circulation pump based on the ALO
threshold and on the readings of sensors T2 and T3.
Operation is signalled on the display by the alternating
OFF and ALO signs.

The key imposes a PLL logic that operates by taking into
account both the actual difference between the temperature
detected by the probe on the return of the water from the
system and the SET setpoint set at 40 °C (adjustable between
20 and 55 °C) and the outside air temperature (climatic reg-
ulation), so as to make the outdoor unit work in heat pump
mode, exploiting the modulation algorithm to the maximum
and, if necessary, activate the auxiliary heater according to
the envisaged regulations.
This adjustment is indicated by the switching on of the
LED
The external condenser is enabled whenever a thermostatic
request is received in accordance with the integration and
switching settings.
The external condenser is disabled in case of alarm.
Disabling is indicated by the LED lighting
Settings are mutually excluding and the setting remains
stored also in case of blackout.
