CAUTION
The adjustment of the Maximum Heating Tempera-
ture is managed by
"PAR 14" (see paragraph "List of
parameters").
6.13.2 External timers and Room Thermostats
The heat demand can be by a "clean contact" conforming to
EN607301 connected to TA (see section
"Wiring diagram" ) or
by use of a dedicated Sime Remote Control (Home or Home
Plus). The boiler will automatically detect when a dedicated
control is connected.
