Fan coil for wall installation, equipped with a serial port for connecting the "LAN" control to the wall, supplied separately (mandatory accessory). It has two independent clean contacts for the activation of a chiller and a boiler, and a presence input.
AUTO function with linear fan speed adjustment. Night operation with fan speed limitation and reduction (winter) or increase (summer) of the set temperature. On the electronic board there are two dip-switches (microswitches) for configuring the operation of the device according to need.
With the first microswitch the logic of night-time heating operation is modified:
- in the ON position, ventilation is inhibited, thus allowing the machine to heat the rooms by irradiation and natural convection, as in traditional radiators;
- in the OFF position, the normal fan operation occurs.
With the second microswitch:
- in the ON position, ventilation is enabled, only in cooling mode, the ventilation continues at minimum speed even after reaching the setpoint to allow a more regular operation of the temperature probe and to avoid air stratification.
- In the OFF position the function is cycled (2 minutes ON, 10 minutes OFF).
This version is suitable for air conditioning commercial environments such as: meeting rooms, receptions, shops, hotel rooms, where there is a need to control several fan coils with a single "LAN" wall control
