3 COMMISSIONING
3.1
Preliminary operations
When the Sime
Open Hybrid SMART
is commissioned, this must
be carried out by a professionally qualified technician who,
before starting the appliance, must check that:
– the type of gas used is the same as that for which the ap-
pliance has been prearranged, the mains network pressure
is suitable and the duct is deaired
– the gas isolation valves for the heating system and the wa-
ter system are open
– the heat pump and boiler siphons are filled and the conden-
sate outlets are routed correctly
– the combustion air and smoke outlet ducts have been exe-
cuted correctly
– the expansion vessels are correctly prefilled.

Heat Pump and setting of relative
parameters
In the FIRST COMMISSIONING phase of the system, check
that the parameters set in the heat pump correspond to those
indicated in the table below.

MLC30 zone board and setting of relative
parameters
3.3.1 Description
The MLC30 zone board zones allows a low temperature and
a high temperature zone to be managed. Through the serial
communication between the boiler board and the
SIME HOME
PLUS
, better comfort levels can be achieved.
The board includes:
– 3 dip switches (see
“Fig. 36” on page 32
)
– pump anti-blocking function
– mixing valve anti-blocking function
– LED status indicator
– post circulation on last zone of origin requested.
3.3.2 Operation
Connection through the open therm (OT) of the boiler guaran-
tees the regularity of the setpoint as the MLC30 board direct-
ly adjusts the delivery temperature on the basis of the active
requests.
The functions differ depending on the type of system present.
For correct operation, the “low temperature zone” (BT) must
be managed by the ambient thermostat (TA). In the event of
a “low temperature zone” request, the mixer is controlled on
opening, the relative zone pump is activated as is the boiler
request. The set setpoint is also sent to the boiler. During the
request, the mixer is controlled on opening and closing to rea-
ch the setpoint set at the relative parameters. A possible “high
temperature zone” request (AT) is met by activating the rela-
tive pump/valve and setting a delivery temperature which is
the same as the maximum of the requesting setpoints. At the
end of the request on the zone (BT), the mixer is controlled on
closing and deactivates the zone pump while for the zone (AT),
the zone valve/pump is deactivated. Post circulation is always
present on the last zone which has requested heat (the mixing
valve is closed completely when the board is powered on).
