"0" No solar control unit installed.
"1" With Vitosolic 100.
"2" With Vitosolic 200.
"3" No function.
"4" Integral solar control function.

7A01 Max. collector temperature !

Only in conjunction with integral solar
control function ("Type solar control
unit 7A00"):
The solar circuit pump will be switched
off if the maximum collector temperature
is reached.

7A02 Start hysteresis solar circuit pump !

Only in conjunction with integral solar
control function ("Type solar control
unit 7A00"):
The set value determines the tempera-
ture differential between the collector
