The AHS function is set on the user interface.(AHS function can be set valid or invalid in “OTHER HEATING SOURCE”
of "FOR SERVICEMAN".);AHS is only controlled by master unit. When master unit operates in DHW mode , AHS can
only be used for producng domestic hot water; when master unit operates in heating mode, AHS can be used for heating
mode.
The TBH function is set on the user interface. (TBH function can be set valid or invalid in “OTHER HEATING SOURCE” of
"FOR SERVICEMAN".) TBH is only controlled by master unit. Please refer to 8.1 Application 1 for TBH control.
