INSTALLATION REQUIREMENTS
Recommended free space around the heat pump for optimal maintenance and
servicing possibilities and duct connections.
On the backside of the heat pump please also respect free space for maintenance
and servicing all hydraulic connections.
All damage and service impossibilities due to reduced accessibilty are part of the
installer/user responsibility and not covered by the manufacturer’s warranty.

The heat pump should always be positioned in correct level or 1° backwards for
the defrost water to run out in a proper way.

SERVICE
6
INSTALLATION REQUIREMENTS
Defrost water tube must be mounted in
correct level of the defrost water outlet of the
heat pump and into the drainage. If tube is
above correct level the defrost water will run
backwards and into the heat pump and could
cause water leakage and this will cause
exclusion of warranty.

When the heat pump is placed at the customer the pallet must be removed.
• Tip or place the heat pump horizontal on the floor for easy dismounting of the pallet
• Loosen the screws that act as adjustable feet. (do not remove the screws)
• Remove the disc from all three feet
• Remove the pallet
REMOVE HEAT PUMP FROM PALLET

SERVICE

To adjust the feet do the following.
• The thrust washer (3) is placed under the adjustment screw
• The lock nut (1) is loosened
• The foot screw (2) is adjusted so that the heat pump is in a vertical position (90° or 1° backwards) and does not tilt
(important for the outlet of the defrost water)
• The lock nut (1) is tightened again.
• Ensure that the heat pump is installed in the right level to keep Manufacturer’s warranty

Minimum temperature.
The temperature can be changed through pressure and again release of the button, the
operating temperature will then flash. By turning the button, the desired minimum water
temperature will occur. If the desired temperature is reached, the button is pressed
again for acceptance. The minimum temperature is normally about. "35°C". If the
water temperature become lower than "T min" , the additional heating system will be
activated, if you in the menu "H.pump" have selected, e.g. "HP+EL" (or HP+Boil if
boiler is installed)
Select the combination of the Heat source.
There are the following options in the program:
"OUT", "HP", "EL", "HP+EL","BOILER", "HP+BOIL".
If no boiler is installed, the last 2 combinations are not in use
Similar function as T min. Used for “Draw Down function" and

Here the automatic Legionella function can be switched on.
If switched ("ON") the heat pump will once weekly increase the
temperature to 65°C, in order to eliminate possible bacteria.
We recommend activating the legionella function in the night time where
hot water is not used.
The procedure must be activated in the parameter menu.
If the legionella procedure is activated, the legionella sequence will start immediately.
If the legionella procedure is deactivated, the legionella sequence will stop immediately.
If activated a new “legionella protection” cycle starts automatically after 7 days (168 hours). The function will be
deactivated at power cut.
In order to protect your installation against “legionella” or other bacteria, the water temperature goes up to 62°C by
means of the HP and the supplementary additional heating. At 62°C the device switches to the “supplementary
heating only mode” to heat further up to 65°C. This temperature is maintained for 1 hour before it will switch back to
normal operating mode. The “legionella protection cycle” is limited to 12 hours. If the legionella temperature is not
reached*, an alarm will be displayed. The alarm will disappear automatically after the next successful legionella
sequence or be reset on user acknowledgement.
* If the air temperature is too low and/or the DHW energy requirement during the “legionella protection” cycle is
higher than the needed output for the “legionella-protection” procedure.

This function permits to operate the DHW HP with cheap and
environmentally friendly energy from your own solar cell panels.
"Off" = Solar cells are not connected to system or not chosen to be used
by the user.

If the signal anode is factory mounted the value of the parameter
“ANODE” is already set to “ON”. If the signal anode is retrofit, the
parameter “ANODE” has to be set manually to “ON”. If a standard anode
is installed, the parameter “ANODE” has to be set to the value “OFF”.
If no signal anode is installed the normal anode must be checked for
replacement with a new anode 1 time per year due to different local
water quality.

Temperature "T max". Here the maximum desired operating temperature
can be adjusted. The temperature adjusted under "T max " is afterwards
the highest possible temperature in menu "SETPOINT".
”T max” can be adjusted from 5°C to 62°C. Please note, that efficiency
of the heat pump is reduced at higher temperatures = higher current
consumption.

ALARM DESCRIPTIONS
There are 3 alarm levels.
• Information alarm.
• Cooling circuit alarm.
• Alarm for the whole heat pump.
3 different alarms can be show at the same time. The alarm must be reset by pressing the control button push/rotate
at the control panel.
The information alarm
• it does not affect the heat pump, but tell the user that there is a problem, which must be solved as soon as
possible. (alarm no. 8, 9 and 10).
The cooling circuit alarm
• warm water production with the compressor stops. When the heating element is chosen, it will take over the hot
water production to the setPoint. (Alarm no. 3, 4, 5 and 6).
Alarm for the whole heat pump
• warm water production stops completely. It acts probably over a defective operating sensor (alarm no. 1 and 2).
The user can see the alarms in the alarm menu when the alarms are acknowledged. The error must be
eliminated and the alarm has to be acknowledged before the normal operation will take place again. If the error is
not eliminated the alarm will continue. In the case of several simultaneous alarms they are placed in row. The
alarms will be shown in a priority list.
