1.1 Explanation of symbols
Warnings
Signal words indicate the seriousness of the hazard in terms of the consequences of not following the safety instructions.
• NOTICE indicates possible damage to property or
equipment, but where there is no risk of injury.
• CAUTION indicates possible injury.
• WARNING indicates possible severe injury.
• DANGER indicates possible risk to life.
Important information

1.2 Safety precautions
General
B Re ad t h e guide c are f u lly and kee p it t o hand fo r fu t u re
use.
Installation and commissioning
B The heat pump may be installed and put into
operation only by a qualified installer.
Risk of damage due to operator error
Operator errors can result in injury and damage to property.
B Ensure that children never operate this appliance
unsupervised or play with it.
B Ensure that only personnel who can operate this
appliance correctly have access to it.
Service and maintenance
B Only qualified personnel may carry out repairs.
Incorrect repairs can lead to serious risks to the user, and a reduction in savings.
B Only use original spare parts.
B Service and maintenance must be carried out annually
by an authorised service representative.
Safety instructions in this document are framed and identified by a warning triangle which is printed on a grey background.
Electrical hazards are identified by a lightning symbol surrounded by a warning triangle.
Notes contain important information in cases where there is no risk of personal injury or material losses and are identified by the symbol shown on the left. They are bordered by horizontal lines above and below the text.

The function is used for monitoring/control from external equipment (3rd party). Data is retrieved separately from all units
that are to be monitored. The communication is Modbus/RTU, RS485.
Operation times, operating status, alarm status, temperatures, set point values, limit values etc are read off via
communication. The set point values can be changed and the heat pump can be force started and force stopped.
The settings do not affect the heat pump operation or cooperation.

Heat curve E21
The flow temperature set points at different outdoor temperatures are automatically calculated using

underfloor systems. Values can be changed individually, for example adjusting the heat curve at 0 °C.

4.3.1 Heat curve
The heat pump operates by holding flow temperature E11.T1 in relation to outdoor temperature E10.T2 according to the set heat curve.
The appearance of the heat curve depends on settings for the minimum outdoor temperature (DOT, factory setting -35 °C), lowest flow set point (factory setting 20 °C) and highest flow set point (60 °C). This heat curve is appropriate for radiator systems.
Fig. 2 Radiator system
When the factory setting is changed, the heat curve is redrawn automatically. Any adjustments to the curve disappear.
The curve is set in E21 and applies to all heat pumps.

The function means that the set point for the flow temperature is successively adjusted with respect
to the set point at the current outdoor temperature. This reduces the effect of brief fluctuations in
outdoor temperature.
