In order to ensure the failure-free and safe operation (to maximum extent) the
controller of boiler is provided with many protection functions. If faulty status is
discovered, the alarm is launched (acoustic signal), and a message is shown on display
(depending on controller version).
TERMAL PROTECTION
The controller is equipped with safety temperature limiter, preserving the boiler against
overheating (boiling water in installation), if the controller is damaged. Temperature limiter
makes up mechanical protection measure, which bimetallic sensor (placed at the boiler water
