Application
The SLIM Heat interface unit is used to provide hot water in properties connected to a district heating system.
Status indicator LED
Green blinking: Normal condition
Blue blinking: Tapping condition
Red blinking: Error
White continuous: Service mode (installer only)
No LED: No power / switched off
Operation
CAUTION!
Components, pipes in and connected to the unit may be
hot. The SLIM is designed for usage with centralized
heating systems up to 900C. The pipes and components
in the unit as well as the pipes and components outside
of the unit can reach these temperatures. Contact may
lead to burns.
The unit is equipped with a single wall plate heat exchanger. The heat exchanger transfers the heat from the
heat distribution system to the domestic hot water. The electronic controller in the unit, together with
electronic control valve, temperature sensors and flow sensor regulates the temperature of the hot water to
its setpoint 45-600C.
The unit has two DHW keep hot modes: Eco mode and Comfort mode (default). Default mode, settings, times
and temperatures can be modified by the installer (during commissioning) using the special service software.
Eco mode
The Eco mode allows the heat exchanger to cool down after the last hot water draw off to conserve energy. It
also has the option of keeping the heat exchanger hot for a limited period of time after the last hot water
draw off. This provides more comfort in situations where regular hot water is needed within a certain period
of time.
Comfort mode
In Comfort mode the heat exchanger and the DH supply pipe are always kept warm for instant hot water
delivery. When in Comfort mode the unit only uses energy to compensate for the heat losses of the DH supply
pipe and the isolated unit.
Legionella prevention
To prevent legionella from growing, the heat exchanger can be heated* every 24 hours for 1 hour. Default
setting is ON (active).
*NOTE: for a correct thermal disinfection a District Heating supply temperature of 60°C is recommended.
(minimal requirement is 55°C).
CAUTION! Hot water
The hot water temperature is regulated to approximately 550C (or other setpoint). If there is a power outage
during tapping conditions the unit will stop regulating the hot water temperature. This may lead to a hot water
temperature that is higher or lower than the setpoint. Hot water can cause burns.

General Plumbing Requirements
Keep following conditions in mind during installation:
•The unit can only be used with closed heating systems up to a temperature of 800C.
•The unit must be stored and installed in a frost free area.
•The unit must not be exposed to direct sunlight.
•Ambient temperature must be between +50C and +400C.
•Humidity must be between 20% and 80%.
•Temperatures of components in the unit and connected to the unit can reach high temperatures. Contact may
lead to burns.
Fitting and modifications
Fitting the appliance and any controls to the appliance may only be carried out by a competent engineer. Any
misuse or unauthorised modifications to the appliance or associated components and systems could invalidate
the guarantee and may lead to serious injury or even death. The manufacturer accepts no liability arising from
any such actions, excluding statutory rights.
District heating
CAUTION!
Components, pipes in and connected to the unit may be hot. The SLIM is designed for usage with centralized
heating systems up to 900C. The pipes and components in the set as well as the pipes and radiators in the
central heating installation can reach these temperatures. Contact may lead to burns.
Keep following conditions in mind during installation:
• Maximum pressure supplied by the district heating network is 16 bar.
•Maximum supplied temperature by the distict heating network is 900C.
•Minimal supply temperature is 550C.
Domestic water
Keep following condition in mind during installation:
• Maximum pressure supplied by the domestic water circuit is 10 bar.
• All seals, joints and compounds (including flux and solder) and components used as part of the secondary
domestic water system must be approved.
•It is highly recommended to fit a filter on the mains cold water line, to filter fine particles such as sand
from the cold water before it enters the heat exchanger. Blockages and malfunctions due to debris in the
water are not covered under the warranty.

General wiring requirements
These instructions must be followed except for any statutory obligations. Component specific electrical
information may also be supplied in support of these instructions.
FAILURE TO INSTALL APPLIANCES CORRECTLY COULD LEAD TO PROSECUTION.
CAUTION!
Be sure to remove the power supply to the unit before starting any work and observe all relevant safety
precautions. The unit uses electrical components (24VDC). These components must stay dry at all times.
Touching these components can result in an electrical shock, burn, or electrocution.
