Optional parts
Optional 1 : Room sensor
To control the system operation by room temperature. See page 48
Optional 4 : HW parts
To manage outlet water temperture. See page 69
Optional 5 : Extra system volume
To ensure minimum required water volume in heating system.
See page 66
Optional 6 : Flow relief valve
To ensure water flow in case thermostats are installed on
radiators. See page 66
Optional 7 : Extra system pump
To ensure water flow in case pressure drop of heating system is
big. See page 68
Optional 8 : Extra system volume only with floor heating / cooling
To ensure minimum required water volume especially for under-
floor system. See page 66
Optional 9 : Non-return valve
To ensure water flow in the extra system pump during HW opera-
tion. See page 68
