OPERATIONAL INSTRUCTIONS

WINTER MODE DUTY

- Open the circulation pump gate valves

- Start the pump

- If the system is equipped with mixing valve: operate 

the valve manually to remove any sediment deposi-

ted inside the valve and check for absence of seizure 

between shutter and valve body, then restore the me-

chanical connection between servomotor and valve.

- Turn knob H     to automatic 1 position (nighttime 

economy/ daytime comfort). 

- Check the timer and set current time. 

If the heating system settings have not been chan-

ged  with  respect  to  the  last  winter  mode  duty,  the 

control  unit  is  set  yet.  Otherwise  repeat  the  ope-

rations  described  in  paragraph    “SETTINGS  AND
