12.2 Switching to Test Mode:

Test Mode Access Procedure:

• Bring R80 to Test Mode and R81 to Summer positions. 
• Using R81, select UW OFF – TEST MODE / UW OFF TEST MODE in 2 seconds. Leave the button in any usage

water temperature. When Test Mode starts 3 leds start to blink. 

• Test mode shall operate the boiler at maximum capacity for 15 minutes. During this operation maximum-minimum

gas pressure adjustment can be done. 

• Test mode can be exited by performing the accessing steps.  When there is usage water demand, test mode is

suspended.
