5.1 Guided commissioning procedure

The Heos controllers can be setup the ﬁ rst time from the pGDe user
terminal connected to J15. After programming, the terminal can be
removed or remain connected.
If the controller has not yet been conﬁ gured, the user terminal shows the
language selection and than the ﬁ rst screen in a guided conﬁ guration
procedure, called the “wizard”. Otherwise, the same menu can be
accessed from branch.

E.Conﬁ guration>>f.default

The main parameters needed for general conﬁ guration are shown one at
a time. The wizard screens are all numbered in the top right corner; the
following explanations refer to this number. To go from one screen to the

next press

, while to return to previous screen press

Important:

at the end of the procedure, exit by powering the unit OFF,

after having exited screen WZ19 by pressing

Screen WZ01:

this shows the code of the application loaded on the

controller (FLSTDmWL0M) and the revision. Pressing

starts the

guided procedure.

Screen WZ02:

select multi-evaporator/individual compressor

conﬁ guration. A group of controllers is called “multi-evaporator” when
multiple controllers (up to 6) are connected in a Master/Slave network,
and share the same compressor, controlled by the Master. If setting “Y” for
the parameter on this screen, the unit will be part of a multi-evaporator
group. Setting “NO”, the unit is conﬁ gured as stand-alone or part of a
Master/Slave group with an individual compressor on each unit.

Screen WZ03

: unit address. The unit can be conﬁ gured as the Master or

as one of the Slaves, setting the parameter to MASTER or SLAVE1, SLAVE2,
… SLAVE 5. Setting this parameter also sets the controller pLAN address
as a consequence: 1 for the Master, 2 for Slave 1, 3 for Slave 2, and so on
up to 6 for Slave 5.

Screen WZ04:

this is only shown if the controller is set as the Master and

the multi-evaporator conﬁ guration has been selected. This speciﬁ es the
number of evaporators connected to the Master. The default value is the
number of Slaves connected.

Screen WZ05:

this is only shown if the controller is set as the Master and

the multi-evaporator conﬁ guration has not been selected. speciﬁ es the
number of Slaves connected to the Master.

Screen WZ06:

evaporator capacity. If the unit is conﬁ gured as part of a

multi-evaporator group, this screen is used to set the rated evaporator
cooling capacity. This data is used to adjust the compressor speed based
on demand from the various units served.

Screen WZ07:

select type of unit. The type of unit can be selected as

SHOWCASE or COLD ROOM. If COLD ROOM is selected, other parameters
are proposed: the position of the door switch and enable/disable the
three temperature probes: outlet, defrost and intake.

Screen WZ08:

select type of unit of measure (SI or Imperial) for

temperature and pressure.

Screen WZ09:

set point and virtual probe composition. This screen

is used to set the control set point and the weight of the outlet and
intake temperature probes in the average for calculating the control
temperature. When the parameter is set to 0%, the virtual probe coincides
with the outlet probe, if set to 100% the virtual probe coincides with the
intake probe.

Screen WZ10:

select type of compressor: BLDC, ON/OFF (single) or ON/

OFF (multiple).

Screen WZ11:

select the digital input for multi compressors.

Screen WZ12:

select compressor and inverter programming. For the

Compressor parameter, any one of the compressors managed by
Heos can be selected. Under the type of compressor, if the inverter is
connected and on, the model of Power+ can be read. If the inverter is
oﬀ or not connected, the last row of the screen displays the message
Power+ not connected. After having conﬁ rmed the type of compressor, if
communication with the inverter is active, Write parameters is displayed;
choosing Y starts writing some of the parameters to the inverter, so as
to ensure correct operation with the selected compressor. During the
write procedure, the display shows Installing parameters…, replaced
by a conﬁ rmation message when the write procedure has ended. If the
control is ﬁ tted on a Slave on a multi-evaporator unit, this screen is not
displayed.

Screen WZ13:

select type and limits of the suction and condensing

pressure probes.

Screen WZ14:

with on-board compressor, if conﬁ guring a Slave in on a

multi-evaporator unit, only the suction probe is proposed.

Screen WZ15:

select the type of outlet, defrost, intake, compressor

suction and compressor discharge temperature probes. If is a Slave unit
being conﬁ gured, the compressor discharge temperature probe is not
displayed.

Screen WZ16:

select the type defrost and main defrost parameters.

Screen WZ17:

select the operating mode for the evaporator fans.

Screen WZ18:

set the parameters for connecting the supervisor.

Screen WZ19:

end the wizard procedure. Pressing ENTER ends the

procedure, and starts conﬁ guring the system with the chosen options.
At the end of the conﬁ guration, the controller needs to reset the unit to
conﬁ rm the data (

WZ20

). Power down the controller for a few seconds

and power on again.
