5.7 Setting a DHW program

With the setting by heating circuit (factory setting), the start and stop times for DHW heating

follow those of the selected switching program. This ensures that DHW is available during the

heating phases (day mode).

If you want to enter a separate DHW program, we recommend:

• Only charging the DHW cylinder once in the morning before the heating start time and possibly

also programming another heating phase in the evening if more hot water is regularly needed at

that time.

This would allow you to significantly reduce your energy consumption even further.

To set a DHW program which is independent of the heating phases:

1. Open the user menu.

2. Select switching programme.

3. Select the domestic hot water heating circuit.

4. Use change switch point to enter, delete or modify a switching point (Æ page 34) or enter a

new program.

5. Save the program as user defined 1 or select do not save to cancel.

6. Check that automatic operation is set for operation mode\domestic hot water to make

sure that the program you have set is also active (Æ page 30).

5.8 Setting a DHW circulation program

You can use a DHW circulation program

to enter the start and stop times for the DHW circulation

pump independently of the switching program for the heating system. Follow the same procedure

as for entering a DHW program (Æ Chapter 5.7).

If you occasionally need more DHW outside the set time, you can activate the DHW

heating for a short time (“Heating up DHW once”, Æ page 18).

1) This function depends on the boiler used.
