4.3 Return connection option
During low demand or circulation, high return temperatures
can be generated. These can be fed to the buffer store at
a higher temperature level using the 3 port valve. This will
avoid mixing with the lower cooler zone.
When the difference between return temperature (T-R) and
store temperature (T-St) exceeds the adjusted switch-on
difference (
D
T R on), relay RC is energised. It is deactiva-
ted when the loading circuit is not operated or when the
difference falls below the adjusted switch-off difference
(
D
T R off).
• Activate the return connection option by selecting „Ret.
con.“ in the „Settings/Fnc. R5“ menu.
• Adjust the switch-on difference (
D
T R on) in the settings
menu
• Adjust the switch-off difference (
D
T R off) in the settings
menu
