14. Fan Coil RHOSS Electronic Board
Main Funtion
COOL – Cooling
HEAT – Heating
DRY – Dehudimifier
FAN – Fan
FULL AUTO – Automatic mode of function, std set-point, adjustable with ±2°C (I FEEL)
HEAT/FULL AUTO + RES EL – Heating with electrical heater

15. Fan Coil RHOSS Electronic Board
Advanced function
HOT START – In heating mode, when the water is too cold, the electrical fan doesn’t start
TOO COOL – In cooling mode, when the water is too hot, the electrical fan doesn’t start
PERIODIC VENTILATION – To avoid the stratification of air
CONTINUOS VENTILATION – The electrical fan run at the minimun speed when the set point soddisfied (only with valves)
SLEEP – During the night, this function increases the summmer set point and it decreases the winter set point
TIMER – It switchs on and switchs off the fan at the setting time

16. Function by free voltage contac
SCR (DI1) – Remote ON/OFF
SIC (DI2) – Safety switch (i.e.: opened window); the display shows A07
EIR (DI3) – Remote Summer/Winter switch; started from dip-switch 2, only if the LOCK FUNCTION is ON
ECO (DI4) – Economy, with SLEEP function

18. Dip-Switch configuration
DS1 – VALVES: ON/OFF valves setting
DS2 – EIR: Remote summer/winter switch
DS3 – LOCK FUNCTION: limited funtion for the users
DS4 – 2/4 PIPES: adictional heat coil
DS5 – EL. HAETER: adictional electrical heater
DS6 – PDC/CHILLER + CALDAIA: the adictional heat water coil can function with main water coil (with Heating Pump)
