SkyStar / SkyStar ECM

The MB electronic board,
mounted as per standard on the SK–MB
and SK–ECM–MB versions, is set to carry out
different functions and adjustment modes,
in order to meet the installation requirements.
These modes are selected
by setting the configuration dip switches
on the board.
• 2/4 pipe system.
• Fan ON/OFF thermostatic control.
• Valve ON/OFF thermostatic control
and continuous ventilation.
• Valve and simultaneous ventilation ON/OFF
thermostatic control.
• Fan operation control
depending on the coil temperature (cut-out T3 probe fitted), which can be activated
only in heating mode or heating and cooling mode.
• Automatic switch of the operating mode
by means of T2 water probe (optional) applied on the 2 pipe system.
• Seasonal switch by means of remote contact.
• ON/OFF of the fan coil by means of the remote contact
(window or clock contact).
• Electric heater control.
By activating the cut-out T3 probe function, the fan is stopped in winter when the coil temperature is lower than 32°C
and started when the temperature reaches 36°C. In summer mode, the fan stops when the temperature inside the
coil exceeds 22°C and starts when it drops below 18°C.
The following connections are located on the power board:
• Receiver for infra-red remote control.
• T-MB wall control.
• RS 485 serial connection to manage several fan coils in Master/Slave configuration
or to create a supervisory network.
