Powering Up The Unit; Setting The Pump Speed; Field Settings - Daikin Altherma EDHQ011AA6V3 Installationsanleitung

8 Refrigerant leak
Check the inside of the unit on refrigerant leakage. If there is a
refrigerant leak, call your local dealer.
9 Power supply voltage
Check the power supply voltage on the local supply panel. The
voltage must correspond to the voltage on the identification label
of the unit.
10 Air purge valve
Make sure the air purge valve is open (at least 2 turns).
11 Pressure relief valve
Check if the backup heater vessel is completely filled with water
by operating the pressure relief valve. It should purge water
instead of air.
Operating the system with the backup heater vessel not
completely filled with water will damage the backup heater!
12 Shut-off valves
Make sure that the shut-off valves are fully open.
Operating the system with closed valves will damage the
pump!

Powering up the unit

When power supply to the unit is turned on, "88" is displayed on the
user interface during its initialisation, which might take up to 30
seconds. During this process the user interface cannot be operated.

Setting the pump speed

The pump speed can be selected on the pump (see "Main
components" on page 8).
The default setting is high speed (I). If the water flow in the system is
too high (e.g., noise of running water in the installation) the speed
can be set to low speed (II).
NOTE The speed dial on the pump indicates 3 speed
settings. However, only 2 speed settings exist: low
speed and high speed. The indicated medium speed
setting on the speed dial is equal to low speed.
The available external static pressure (ESP, expressed in mH
function of the water flow (l/min) is shown in the graph below.

Field settings

The unit should be configured by the installer to match the installation
environment (outdoor climate, installed options, etc.) and user
demand. Thereto, a number of so called field settings are available.
These field settings are accessible and programmable through the
user interface.
Each field setting is assigned a 3-digit number or code, for example
[5-03], which is indicated on the user interface display. The first digit
[5] indicates the 'first code' or field setting group. The second and
third digit [03] together indicate the 'second code'.
A list of all field settings and default values is given under "Field
settings table" on page 26. In this same list, we provided for 2
columns to register the date and value of altered field settings at
variance with the default value.
A detailed description of each field setting is given under "Detailed
description" on page 21.
