Manual background

Appendix

When there is no heating operation or when the flow temperature in the system is lower, the storage tank charging pump is switched on immediately.

If a storage tank thermostat is used, the storage tank charging pump is switched on when the temperature T = Charging temperature – 5 °C is reached at sensor VFS.

Note!

The charging temperature VFS is controlled in system Anl 2 by the primary valve. In all the other systems (Anl 4, 5, 7, 8, 9 and 10) the mixing valve regulates the charging temperature VFS.

When the Circulations pump function is active, the circulation pump remains in operation ac- cording to the time schedule. The pumps is switched off when this function is deactivated.

The Mixing valve always active function allows the heat exchanger to maintain the charging temperature using the mixing valve. The heat exchanger charging pump remains switched on and the return flow temperature is not limited outside the times-of-use.

Stop storage tank charging

The controller stops charging the storage tank when the water temperature in the storage tank measured at sensor SF1 exceeds the temperature T = Charging temperature + Hysteresis by

0.1°C. When there is no heating operation or when the flow temperature demand in the system is lower, the corresponding valve is closed.

The storage tank charging pump is switched off when the charging temperature at sensor VFS has fallen below the Storage tank charging pump deactivation limit; however, at the latest, af- ter t = 2 x Transit time of the primary valve.

In the default setting, the storage tank is charged by 5 °C to at least 50 °C when the storage tank temperature falls below 40 °C. The charging temperature is 55 °C. On completing the storage tank charging, the heating valve is closed and the charging pump continues to run until the charging temperature falls below 50 °C.

Functions	WE	Configuration
Storage sensor SF1	ON	Co4 -> Fb00 = ON
Storage tank system	OFF	Co4 -> Fb10 = ON
Circulation pump	OFF	Co4 -> Fb04
Mixing valve always active	OFF	Co4 -> Fb11
