•
set the boiler mode to STANDBY (section 5.3)
•
in the paused state, the controller of the boiler has a protective function described in section 5.3 - “Performed functions”.
If you decide to discontinue using the boiler for a long time, you should:
•
set the mode on STANDBY (section 5.3)
•
drain the boiler’s water system and also the C.H. system using the drain valve (item 33 Fig 2.2.1.1 and 2.2.1.2) if freezing
is a possibility
•
close the water and gas valves and disconnect the boiler from the power supply.
NOTE!
During winter (because of the risk of water freezing in the system), disconnecting the boiler from the electrical system
is forbidden, if there is still water in the boiler’s water system.
