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 (DT 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

(DT R off).

• Activate the return connection option by selecting „Ret.

con." in the „Settings/Fnc. R5" menu.

• Adjust the switch-on difference (DT R on) in the settings

• Adjust the switch-off difference (DT R off) in the settings
