STB function manual reactivation
When the STB temperature limiter has been triggers and fan deactivated, its operation must
unconditionally be restored in order to ensure the proper functioning of the G-406-P11 controller.
In order for the unit to be reactivated, proceed as follows:
Damage or breaking to the capillary tube means the leaks of the
temperature limiter filled with liquid, which leads to the G-406-
P11 misperformance.
Should such fault be found, the temperature limiter should be
disconnected from the G-406-P11 controller, dismantled and
replaced with the brand new one.

Starting the unit
1. Connect the unit to the power supply network (insert the plug to the plug-in socket).

boiler operation parameters (see item 6).
