• T3 is the DHW temperature by an immer-
sion sensor.
• DO NOT CHANGE this parameter from
the factory setting. ( Boiler outlet water
temperature setpoint in dHW mode is de-
termined by adding Parameter 1 to Param-
eter 33.)
• If applied for instantaneous DHW opera-
tion (not recommended), set Parameter 35

WARNING- it is not recommended to
set this parameter to either “2” or “3” (con-
tinuous dHW pump). this could result in
a hazardous condition, because it causes
constant circulation between the boiler and
the dHW heater.
