7 Start-UP

7.1 General Information

To ensure that start-up is performed correctly, it should only be

carried out by an after-sales service technician authorised by the

manufacturer. This may be a condition for extending the guaran-

tee (see Warranty Service).

7.2 Preparation

The following items need to be checked prior to start-up:

All of the heat pump connections must be established as de-

scribed in Chapter 6.

All valves that could impair the proper flow of the heating

water in the heating circuit must be open.

The air intake and air outlet paths must be clear.

The ventilator must turn in the direction indicated by the ar-

row.

The heat pump controller must be adapted to the heating

system in accordance with the controller's operating instruc-

tions.

Ensure the condensate outflow functions.

The outflow from the heating water pressure relief valve

must also function correctly.

De-aeration of the heating system:

Ensure that all heating circuits are open and the heat circu-

lating pump is operating (level III).

Connect the voltage to the heat pump controller. Select the

heat generator 2 operating mode and de-aerate the system

at its highest point. Top up with water if required (maintain

static minimum pressure).

7.3 Start-Up Procedure

The heat pump is started up via the heat pump controller. Adjust-

ments should be made in compliance with the instructions.

The performance level of the circulating pump must be adapted

to the respective heating system.

The overflow valve must be adjusted to the requirements of the

respective heating system. Incorrect adjustment can lead to

faulty operation and increased energy consumption. We recom-

mend carrying out the following procedure to correctly adjust the

overflow valve:

Close all of the heating circuits that may also be closed during

operation (depending on the type of heat pump usage) so that

the most unfavourable operating state - with respect to the water

flow rate - is achieved. This normally means the heating circuits

of the rooms on the south and west sides of the building. At least

one heating circuit must remain open (e.g. bathroom).

The overflow valve should be opened far enough to produce the

maximum temperature spread between the heating flow and re-

turn flow listed in the following table for the current heat source

temperature. The temperature spread should be measured as

close as possible to the heat pump. The heating element of mono

energy systems should be disconnected.

Any faults occurring during operation are also displayed on the

heat pump controller and can be corrected as described in the

operating instructions of the heat pump controller.

For external temperatures below 10 °C and heating water tem-

peratures below 16 °C, the buffer tank should be heated up with

the 2nd heat generator to at least 25 °C.

Observe the following procedure to implement a smooth start-up:

1) Close all of the heating circuits.

2) Fully open the overflow valve.

3) Use the controller to select the automatic operating mode.

4) Wait until the buffer tank has reached a temperature of at

least 25 °C.

5) Now slowly reopen the heating circuit valves in succession

so that the heating water throughput is constantly raised by

slightly opening the respective heating circuit. The heating

water temperature in the buffer tank must not be allowed to

drop below 20 °C during this process. This ensures that the

heat pump can be defrosted at any time.

6) Set the minimum volume flow quantity on the overflow valve

and heat circulating pump when all heating circuits are fully

open and a heating water temperature in the buffer tank of

approx. 20 °C is maintained.

7) New buildings have an increased heat consumption on ac-

count of the energy required to dry them out. This increased

heat consumption means that marginally dimensioned heat-

ing systems can not always achieve the desired room tem-

perature. In such cases, we recommend keeping a 2nd heat

generator on standby during the first heating period. The

limit temperature on the heat pump controller should also be

turned up to 15 °C.
