3. SETTING THE MV8 CONTROL
3.1.1. DIP switch setting
The MV8 control must be set to adapt to the type of operation of the fan coil.
The types of operation are as follows:
PR0 - Fan Only: when the ambient temperature reaches the set point the MV8 control stops the fan.
PR1 - Water valve: when the ambient temperature reaches the set point the control closes the water valve and
drops the fan speed to the minimum.
PR2 - Water valve + strip heater: similar behaviour for the cool mode; when instead the ambient temperature
drops below the set point the MV8 control powers the electrical heater.
The setting is made by means of two dip switches identified in the picture:
The MV8 board comes non programmed and the 2 dip switches are both in OFF which corresponds to NPR
– No Program.
SET the dip switches of the MV8 control to comply to the configuration of the Fan coil.
