AUTOMATIC TEMPERATURE CONTROL
Automatic temperature control only works with the outdoor temperature sensor connected. As soon as you install the
outdoor temperature sensor, connect it immediately to the relevant terminals
on the CH circuit (BAG) control card
(see
page 30).
The boiler will now be able to function with AUTOMATIC TEMPERATURE CONTROL.
The automatic central heating temperature control curve maintains a theoretical room temperature despite changes in
outdoor temperature.
The low temperature zones are served through mixer valves that regulate flow temperature according to a value calcu-
lated by the BAG control card on the basis of outdoor temperature.
The preset coefficient is K=1 (see graph).
Flow temperature to the high temperature zone is also calculated by the automatic temperature control system.
The preset coefficient is K=2 (see graph).
