Delay in connection after a power outage limits output adjustment.

A. Overheating (maximum safe) temperature
Connected output becomes disconnected immediately when the temperature exceeds set point value by
more than 5 °C. Reconnection takes place when temperature falls below overheating (maximum safe)
temperature.
B. Malfunction at boiler temperature sensor
Output is not switched on despite temperature being below set point value. Replace sensor. Acknow-
ledge alarm by keeping boiler switched off for 10 seconds, turn main switch to position 0.

Remote control activated.
Rapid flashes
By-passing of the connection delay: SNABB (Quick) button, item 13 in wiring diagram, keep button
pressed down until status indicator is illuminated steadily.

Temperature diagram: This shows the dependence of the temperature of the flow water on the selected graph and the
outside temperature.
12. Maximum temperature: Highest allowed temperature, 60 °C, (not adjustable).
13. Alternative temperature: The temperature of the outgoing water can be increased/decreased ±15 °C in relation to the
normal temperature. Adjustments are implemented by using the selector switch, see item 5 above.

14. Water temperature flow rates used as the output values available on the graph are used in the floor heating calcula-
tions. If these values are not available, use graph 1 for under floor heating systems laid over a timber sub-floors. If the
loops of tubing are embedded in concrete, use a lower graph, e.g. 0.75.
15. Minimum temperature: Lowest allowed temperature of flow water. If there is no particular requirement, do the installa-
tion for a temperature of 20 °C.
