The MB electronic board, mounted as per standard on the YHVP-MB and YHVP-ECM-MB, 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.
• 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).
• 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.
• JTM-B wall control.
• RS 485 serial connection to manage several fan coils in Master/Slave configuration or to create a supervision network.
