System description
Principle of operation
SCU 10 has been specially developed to work with NIBE's
heat pumps and existing heating and hot water equipment.
SCU 10 can be used with a number of different connection
options. With SCU 10 control the heat is spread from the
solar panel to the heat store, i.e. the accumulator and is
stored there when the sun is shining. The stored heat is then
distributed and used when the need arises.

General information for the installer
SCU 10 used when docking solar heating to your heating
system. For control to start working, it must be activated in
the operating menu.
Docking
The safety equipment must be installed in accordance with
current regulations for all docking options.
See www.nibe.se/docking for more docking options.
Inspection of the installation
Current regulations require the heating installation to be in-
spected before it is commissioned. The inspection must be
carried out by a suitably qualified person and should be
documented. The above applies to installations with a closed
expansion vessel. If the electric boiler or the expansion vessel
is replaced, the installation must be inspected again.
LEK
NOTE
Work behind panels secured by screws may only be
carried out by a qualified installation engineer.
NOTE
Electrical installation and service must be carried out
under the supervision of a qualified electrician.
Electrical installation and wiring must be carried out
in accordance with the stipulations in force.
NOTE
To prevent interference, sensor cables and communic-
ation cables must be separated (min 20 cm) from high
voltage cable when cable routing.

Protection functions
Temp boil
Stops the charge pump at set value on the solar panel. This
is to prevent steam build up in the solar circuit.
Default value 140 °C.
Cooling coll.
If the temperature in the solar panel exceeds the set value,
the charge pump starts to cool the collector, even if the tar-
get temperature (set temp) in the tank is achieved. This
continues until the tank temperature reaches 95 °C.
Cool. tank start/Cool. tank stop
If the tank temperature has reached the target temperature
(set temp) and the solar panel has reached above "cooling
collector", the heat in the tank will be transferred to the
collector again, when the collector temperature then falls
again below the set value "Cooling start". This continues
until the tank temperature goes down to "Cooling stop".

Cooling
The cooling function is used to cool the tank down in the
event of high solar radiation. The function also allows the
transfer of heat to other heat storage (e.g. pool).

Difference control function
Difference control function is used to transfer heat between
tanks regardless of solar charging. The temperature in both
tanks is measured and the control transfers heat from the
”hot tank” to the ”cold tank”, when possible according to

select “yes”.
႑This function is used to detect a temperature increase on
the sensor even when it is not mounted directly where
the temperature increase occurs. The function runs the
pump for 30 seconds every 30 minutes to detect whether
solar radiation is sufficient to start charging.
႑This function only needs to be activated when the solar
panel sensor is not directly located on the solar panel
collector.

႑Temperature level in the solar panel to activate the over-
heating protection. (Adjustable 100 °C to 180 °C with
default value 140 °C.)
Overheating protection for solar panel. The protection means
that the pump stops the circulation when the solar panel
temperature is above “Temp boil”.

Cooling is used to protect the liquid in the solar panel and
works as follows: Pump P1 or P2 starts if the temperature in
solar panel (T1) or (T2) exceeds the “Cooling coll.” setting,
even if the set maximum temperature in the tank has been
reached. Circulation stops when the temperature in the solar
panel has dropped 10 °C. (Circulation stops if the temperat-
ure in the tank reaches 95 °C.)
Re-cooling
The pump is activated to cool the tank down through the
solar panel, if the temperature in the tank is above the set
maximum level and the temperature in the solar panel is 10
°C lower.
The pump stops when the temperature in the tank has
dropped to the set maximum level or the temperature differ-
ence between the tank and solar panel is less than 2 °C.

Freeze protection (liquid)
If anti freeze is selected, the temperature in the solar panels
(T1) and (T2) is maintained above the anti freeze temperature
(see below) by activating pump P1 or P2.
If the system is frost protected by for example glycol, this
function should not be used.
If liquid water is selected the frost protection is activ-
ated.
This function can be used to remove snow from the solar
panel and thereby increase efficiency. The liquid in the solar
coil is protected against freezing.
NOTE
You should not use this type of anti freeze where it is
regularly cold or cold for long periods.

Monitoring the flow
The flow in the system is also monitored if a flow meter is
not installed. The temperature difference between the solar
panel and the tank is used to indicate flow problems. If the
difference is greater than 60 °C, for longer than 30 minutes,
this is interpreted as a flow error. If a flow meter is installed
and a flow has not been measured for ten minutes after the
pump has started, a flow error is indicated. If the 60 °C/30
minimum criteria occurs, control stops and an error message
appears in the display. But if the flow meter indicates an error
this is only indicated in the display and control continues.

Prioritised Tank
(Only available in systems with two tanks (2 and 3)
႑In this menu you can select which tank is to be prioritised
in a two tank system, 1 or 2. If charging starts towards
the non-prioritised tank (if it is colder) charging switches
over to the prioritised tank when the non-prioritised tank
reaches the same temperature as the prioritised one.
When the prioritised tank reaches the maximum temper-
ature (according to the setting) charging switches back
to fully charge the non-prioritised tank.
