(*) High temperature operation: 60°C at boiler return line and 80°C at boiler delivery line.
(**) Low temperature operation: For condensing boilers 30°C, for low temperature boilers 37°C, for other heating appliances 50°C return line
temperature.
NOTE (if the external probe or the control panel, or even both devices, are present in the boiler)
With reference to the Delegated Regulation (EU) No. 811/2013, the information in the table can be used for completing the product data sheet and the
labeling for room heating appliances, for mixed heating appliances, for all those appliances for enclosed space heating, for temperature control devices
and solar devices:
