1 - INSTALLATION
Pag. 1
1.1 Electrical connection
It's very easy to connect Vega MK II to the powerboard using an eight
poles cable (straight) and a RJ45 connector. The standard length of this
cable is four meters.
1.2 Power On
Power On means that the panel is supplied. In Power On the following information is
given: [r x.x].
1.3 Software relay
The indication looks like the following: [rx.x].
1.4 Program from the powerboard
Vega MK II panel connected to a FAN COIL UNIT
The Vega MK II panel connected to a Fan Coil unit. It is a digital panel that can set
up both Fan Coil units and Compact and Split units, because it recognizes automati-
cally the system to which it is connected.
You can identify the unit model thanks to the dip switch on the unit powerboard ( for
Compact and Split units the model and for Fan Coil units the configuration).
If the Vega MK II panel is connected to a Fan Coil unit, there are four programs types
that can be downloaded (with water valve, Fan Only, with strip heater).
Vega MK II panel connected to a COMPACT or SPLIT UNIT
The powerboard of the Compact or the Split unit is already set out for the model
(EH, CO, RC). Only for replacement powerboards the setting out is neutral (dip
switch OFF-OFF).

1 - INSTALLATION
Pag. 2
IMPORTANT
Check that the program downloaded for Vega MK II corresponds to the unit type
actually connected to.
1.5 Positioning of the panel (Temperature internal probe)
Since the temperature probe installed in the panel feels the ambient temperature, the
panel should NOT be installed:
1) Directly exposed to the sunlight (for example, in front of a window);
2) In air stagnation areas (for example, between many pieces of furniture or behind
doors);
3) In areas next to heat springs (for example, near incandescent lamps)
In case of anomalies during the functioning due to the panel position, you have to use
the external probe (see 1.6), that replaces the probe in the panel.
1.6 Temperature external probe (as option)
External probe (code MSENS)
The external probe must be connected to the RJ12 connector "Probe" on the power-
board in the electrical box. The connection to the external probe excludes automati-
cally the internal probe. It is better to fasten the sensitive bulb of this probe on the con-
ditioner or the fan coil suction.

Pag. 3
2.1 ON / OFF button
It switches on and off the unit.
When it is on, the display shows the ambient temperature (or abbreviations, such as
U, d, FO if you have set up the corresponding special functions) and also the Heat and
Cool and the Fan warning lights.
When it is off, the display shows only the ambient temperature.
2.2 S button
Set/Select button.
It is used to enter the programming menu (if pressed for 3 seconds) and to confirm the
parameters change (if pressed by 5 seconds to save the new value).
2.3 Arrow up/Arrow Down buttons
They have got three functions:
1) When the panel is on, they let enter directly the menus (respectively Arrow Up for
SET and Arrow Down for FAN). At this point, it is sufficient to press the S button to
enter the respective menus and to display or to change some values or the setting out.
2) They let move in the menus.
3) They let change the parameters values during the programming.
2.4 Display
Display with three numeric characters and seven segments.
It display the ambient temperature (both when the panel is on and when it is off).
When it is on, it displays also eventual alarms, messages or special functioning modes
abbreviations.

2.5 Functioning warning lights
Cool
It indicates that the conditioning system is in Cool Mode.
If the Vega MK II panel is connected to a Fan Coil unit, the COOL warning light blinks
when the Cool Mode is on but the circulation water temperature is too warm.
Heat
It indicates that the conditioning system is in Heat Mode.
If the Vega MK II panel is connected to a Fan Coil unit, the HEAT warning light blinks
when the Heat Mode is on but the circulation water temperature is too cool.
Auto
It indicates that the fan control is in Automatic Mode.
In this case the Vega MK II panel controls the fan speed, increasing or decreasing it
automatically to reach and keep the set out temperature (Set Point). When the AUTO
warning light is not blinking, the fan is in Manual Mode, so its speed is chosen by the
user and it will not change automatically.
Fan speed
The four warning lights indicate the fan speed: from minimum on the left to the extra-
maximum on the right.
2.6 Probes
In the Vega MK II panel there are two probes:
Infrared probe, at the top in the center, to communicate with the radio-control device.
Temperature internal probe at the bottom under the buttons area.

Temperature probes setting out parameters
Parameter C95
It is the internal probe offset. This parameter is used to change the temperature felt by
the internal probe. The value displayed in the parameter C95 is subtracted to the real
value read by the probe.
For example:
C95=3
Real temperature felt by the probe=25° C
Changed and displayed temperature=25-3=22° C
Parameter C96
It is the external probe offset.
This parameter is used to change the temperature felt by the external probe. The
value displayed is added (if positive) or subtracted (if negative) to the real temperatu-
re felt by the probe.
For example:
C96=3
Real temperature felt by the probe=25° C
Changed and displayed temperature=25+3=28° C
Real temperature felt by the probe=25° C
Changed and displayed temperature=25-3=22° C
