3 .3 .6 Activation
According to Directive 842/2006/EC, systems containing 3 kg or
more of fluorinated greenhouse gases (F-gas) must be checked
for leakage at least once a year, using direct or indirect measur-
ing methods, by certified personnel in compliance with Regula-
tion 303/2008/EC. The maintenance company must also keep
a register in which be identified the technician who performed
the servicing or repair, as well as the dates and results of inspec-
tions carried out, it shows the amount and type of fluorinated
greenhouse gases used, any quantities added and the quantity
recovered during servicing, maintenance and final disposal.
Turn on the device by using the Standby A tile.
Select cooling
or heating
function using tiles B and C.
Check that the temperatures of the water in the hot water
boiler and in the system are shown in tiles F and G.
At this point, if the temperature of the hot water boiler is lower
than the setpoint (45°C by default) tile G on the touch screen
interface and the LEDs
and
on the emergency interface
will light up. The external unit will start in heat pump mode after
a variable time from 2 to 5 minutes (needed by the device to run
internal checks).
On the contrary, the external unit will start to satisfy the request
if the hot water boiler setpoint is satisfied, the TA contact is
closed and the temperature measured by sensor T1 is higher in
cooling or lower in heating * than the required setpoint.
The programs are mutually excluding and the setting remains
stored also in case of blackout.
3 .3 .7 Deactivation
Press the Standby A tile on the touch screen interface.
3 .3 .8 Checks during and after the first start-up
When the start-up has been completed check that:
– The current absorbed by the compressor should be less than
the maximum indicated in the “Power supply line dimension-
ing” table.
Check that the power supply voltage does not fall below the
nominal value -10% while the compressor is in operation.
– Three-phase power may be maximum phase imbalance of
3%.
– The unit operates in the recommended operating conditions
(see “technical data” chapter
– All air has been completely vented from the hydraulic circuit.
– The hydrometer pressure is between 1 and 2 bar.
– The air-water heat pump stops and then restarts.
– Always check the thermal gradient between system outlet
and return is between 4 and 7°C. Set a lower circulator speed
if the thermal gradient is lower than 4 °C. On the contrary, if
the thermal gradient is higher than 7 °C check the opening
of all valves on the system and then add an external pump to
increase the water flow rate.
Disconnect and reconnect power to the device and check
that it restarts correctly.
