 • 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 

for the correct configuration.

•  Parameter  2  determines  whether  DHW 
heating is activated. the boiler will not op-
erate in dHW mode if this parameter is set 
to “0” or “3”.

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.
