What Should water pressure be on ATAG boiler?

The system pressure should be set around 1.0 – 1.2 bar when the water is cold. When the system is working and the water is heated up within the system, since water expands due to heat and you may see the pressure rise up to around 1.8 – 2.4bar.

What are the error codes for the ATAG boiler?

Atag Boiler Error Codes Atag Boilers Fault Code Possible Cause 10 Outside sensor error 20 Flow sensor error 40 Return sensor error 50 DHW sensor error (iC-Range only)

How does a ATAG combi boiler work?

ATAG combi boilers send hot water instantly to the radiators or hot water tap depending which you need at the time. A diverter valve directs the water to the appropriate outlet but from time to time, especially on older boilers, they can get stuck, meaning that even though you’re turning the hot tap on, the radiators are getting warm.
