Heating mode
To start the unit in heating mode, press the
key. The green led is on. If requested, the compressor safety delay
countdown starts and the compressor icon flashes. The water pump will be activated after few seconds and then, once the
compressor countdown has finished, the compressor starts and the icon remains on. The display shows the user water inlet
temperature and Domestic hot water inlet temperature.
Domestic hot water mode
At the first start up, the unit microprocessor control checks the domestic hot water inlet temperature measured by the sensor
BTS (this has priority over the other parameters) and, if the measured temperature is lower than the domestic hot water set
point , it will activate the domestic hot water mode automatically. If the unit is required to operate in heating and the domestic
hot water temperature is higher than the set point (there is no requirement for domestic hot water) the microprocessor
control will activate the unit in heating mode. If the unit is required to operate in cooling and domestic hot water mode the
microprocessor control will activate both functions at the same time. If domestic hot water is not required, the
microprocessor control will activate cooling mode only.

When the unit is switched off from the keyboard or the remote panel, it goes into standby mode. In this mode, the
microprocessor control displays the sensor readings and is also able to manage alarm situations. The only visible signal on the
display is the green led of circuit1 and the water temperatures. If the unit is switched off from remote ON/OFF the label
OFF is displayed.
If it is required to switch the unit on or off, never do this using the main isolator: this should only be used to disconnect the unit
from the power supply when the unit is to be permanently off. Isolation will result in no supply for the crankcase heater and on
start up the compressor could be seriously damaged
