Start storage tank charging

The controller can be reconfigured for all systems with DHW heating to control a DHW storage tank with heating register (storage tank system).

The controller switches the storage tank charging pump (SLP) on and off and controls the mixing valve for the DHW circuit. A mixing valve in the DHW circuit does not exist in system Anl 2. The sensor VFS is connected to terminal 28 and the storage tank charging pump to terminal 45.

The controller starts the storage tank charging when the water temperature measured at sensor SF1 falls below the DHW demand ON by 0.1 °C. If the flow temperature in the system is higher than the required charging temperature, the controller attempts to reduce it in the heating circuit for maximum three minutes before the storage tank charging pump starts to run.
