3 PR] - Display shows [NA]1 - Electrical connectionIt's very easy to connect Vega MK II to the powerboard using an eightpoles cable (straight) and a RJ45 connector. The standard length of thiscable is four Power OnPower On means that the panel is supplied. In Power On the following information isgiven: [r ]. Software relayThe indication looks like the following: [ ]. Program from the powerboardVega MK II panel connected to a FAN COIL UNITThe Vega MK II panel connected to a Fan Coil unit. It is a Digital panel that can setup both Fan Coil units and Compact and Split units, because it recognizes automati-cally the system to which it is can identify the unit model thanks to the dip switch on the unit powerboard ( forCompact and Split units the model and for Fan Coil units the configuration).

4 If the Vega MK II panel is connected to a Fan Coil unit, there are four programs typesthat can be downloaded (with water valve, Fan Only, with strip heater).Vega MK II panel connected to a COMPACT or SPLIT UNITThe 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 (dipswitch OFF-OFF).1 - that the program downloaded for Vega MK II corresponds to the unit typeactually connected Positioning of the panel (Temperature internal probe)Since the temperature probe installed in the panel feels the ambient temperature, thepanel 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 behinddoors).

5 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 usethe external probe (see ), that replaces the probe in the 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.

6 2 - GENERAL DESCRIPTION OF THE VEGA MK II ON / OFF buttonIt switches on and off the it is on, the display shows the ambient temperature (or abbreviations, such asU, d, FO if you have set up the corresponding special functions) and also the Heat andCool and the Fan warning it is off, the display shows only the ambient S buttonSet/Select is used to enter the programming menu (if pressed for 3 seconds) and to confirm theparameters change (if pressed by 5 seconds to save the new value). Arrow up/Arrow Down buttonsThey have got three functions:1) When the panel is on, they let enter directly the menus (respectively Arrow Up forSET and Arrow Down for FAN).

7 At this point, it is sufficient to press the S button toenter the respective menus and to display or to change some values or the setting ) They let move in the ) They let change the parameters values during the DisplayDisplay with three numeric characters and seven 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 - GENERAL DESCRIPTION OF THE VEGA MK II Functioning warning lightsCool It indicates that the conditioning system is in Cool the Vega MK II panel is connected to a Fan Coil unit, the COOL warning light blinkswhen the Cool Mode is on but the circulation water temperature is too It indicates that the conditioning system is in Heat the Vega MK II panel is connected to a Fan Coil unit.

8 The HEAT warning light blinkswhen the Heat Mode is on but the circulation water temperature is too It indicates that the fan control is in Automatic this case the Vega MK II panel controls the fan speed, increasing or decreasing itautomatically 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 theuser and it will not change speed The four warning lights indicate the fan speed: from minimum on the left to the extra-maximum on the ProbesIn the Vega MK II panel there are two probes.

9 Infrared probe, at the top in the center, to communicate with the radio-control internal probe at the bottom under the buttons - GENERAL DESCRIPTION OF THE VEGA MK II probes setting out parametersParameter C95It is the internal probe offset. This parameter is used to change the temperature felt bythe internal probe. The value displayed in the parameter C95 is subtracted to the realvalue read by the example:C95=3 Real temperature felt by the probe=25 CChanged and displayed temperature=25-3=22 CParameter C96It is the external probe parameter is used to change the temperature felt by the external probe.

10 Thevalue displayed is added (if positive) or subtracted (if negative) to the real temperatu-re felt by the example:C96=3 Real temperature felt by the probe=25 CChanged and displayed temperature=25+3=28 CReal temperature felt by the probe=25 CChanged and displayed temperature=25-3=22 C3 - SETTING Set Point (Default=25 C)The Set Point is the temperature you desire to have. The Default Set Point is 25 to display the chosen Set PointPress the Arrow Up button and then the S button. After 5 seconds the display will showagain the ambient to change the Set PointWith the panel (with quick choice)Press the Arrow Up button > [SET] > Press the S button > Press the Arrow Up or theArrow Down button to select the desired temperature > Press the S button to record itWith the remote-control devicePress the button + to increase the Set the button - to decrease the Set Functioning Modes (Default=A)
