The electronic board, mounted as per standard on the YHVP-T and YHVP-ECM-T, 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

(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).

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 infra-red remote control allows setting by a remote position the fan coil operation parameters.
The RT03 infra-red remote control features the following functions:
• Switch the appliance ON and OFF.
• Temperature set.
• Set the fan speed (low, medium, high or autofan).
• Set the operation mode (fan only, cooling, heating).
