Product details
1Product details
The TDS 10 is a controller for use with
thermal solar heating systems that use
heat from the sun to heat a hot water
tank or intermediate heat store.
1.1 Intended use
Th is a cce sso ry may only b e us ed i n th e
types of system specified above.
Any other type of use is beyond the
purpose for which this device is
intended. The manufacturer will not be
liable for any loss or damage resulting
from such use.
1.2 Standard package
• Solar system controller TDS 10.
• 2 PTC-type temperature sensors:
– Solar-panel temperature
sensor.
– Storage tank temperature
sensor for lower tank zone.

1.4 Description of function
For a simplified diagram of the system,
refer to Figure 2 on page 16.
Temperature differential regulator
The temperature differential regulator
controls the operation of the solar heating system pump.
• The solar heating system pump is
switched on when the difference
between the solar panel temperature and the storage tank temperature exceeds the ON threshold
of
8 K (°C).
The display shows the sun symbol
and the symbol moves (Fig. 3).
• The solar heating system pump is
switched off when the difference
between the solar panel temperature and the storage tank temperature falls below the OFF
threshold of 4 K.
The sun symbol disappears from the
display and the symbol stops
moving (Fig. 3).
ON threshold for solar heating system pump:
- ≥ temperature difference of 8 K
OFF threshold for solar heating system pump:
- ≤ temperature difference of 4 K.
Storage tank temperature limiter
The storage tank temperature limiter
prevents the domestic hot water
becoming too hot:
Normal setting = 60°C.
Warning: Risk of
scalding from storage
tank temperatures
over 60 °C!
B Fit a thermostatic mix-
er to the hot water
draw off pipe and set
to 60 °C max.
Function:
• The solar heating system pump is
switched off if the storage tank temperature sensor reading exceeds
the set temperature. The symbol
stops moving and max flashes
(Fig. 4, page 16).
• The solar heating system pump is
switched on again as soon as the
storage tank temperature drops
below the set temperature limit by
4 K. The symbol moves and max
disappears from the display (Fig. 4,
page 16).

Product details
Solar panel high-temperature cutout (fixed setting)
• Above a temperature of 130 °C at
the solar panel temperature sensor
the solar heating system pump
switches off.
The display shows the hot panel/
evaporation symbol and the symbol stops moving (Fig. 5, page 16).
• The solar heating system pump
does not switch on again until the
solar panel temperature has
dropped below 127 °C and the storage tank temperature sensor
calls for heat.
• At temperatures above 140 °C the
convector fluid evaporates in the
solar panel.
Indication of excessive temperature difference (fixed setting)
• If the temperature difference -
is greater than 80 K, this can be a
sign that there is air in the system or
that the solar heating system pump
is defective.
Display error message: SYS.

1.6 Unvented DHW Cylinders
When connecting the Greenskie's
Solar Heating System to an un-vented
hot water storage cylinder, it is recommended that the electrical supply to
the solar control system is taken via the
thermal cut-out device on the cylinder.
