Page 4: Important To Remember
◗ Any work on the product should be done by authorised personnel only. ◗ Safety valve check: the safety valve for the boiler/system and warm tap water should be checked regularly. Refer to the Operation and Maintenance section. CTC EcoZenith I 550... - Page 5 CTC EcoZenith I 550...

-15°C (if the adjustment is set at 0). If the adjustment is set at +5, the temperature will be 55°C instead. At all temperatures out, the curve is increased with 5°C, i.e. the curve is displaced in parallel by 5°C.

Page 9: Hot Water
Hot water The CTC EcoZenith I 550 has a total of approx. 40 m finned copper coils for the heating of hot water. They preheat the water through the lower tank and thereafter run through the upper tank for the final temperature increase. It is two coils running parallel through the tanks, which allow for high flows with low pressure differential and provide great possibilities for good hot water capacity and comfort. - Page 10 ◗ Avoid running hot water with the highest capacity. If you run a bath somewhat slower instead, you get a higher temperature. ◗ Remember that a poor mixing valve by the EcoZenith or a poor shower mixer can affect the hot water temperature.

50°C within the factory-set 20 minutes of charging, the diverting valves reverse the direction and the heat pump charges the lower tank. This is done in order not to lose temperature in the heating system. CTC EcoZenith I 550... - Page 16 This saves compressor life and maximizes the operating economy. The immersion heater, which is factory installed in the lower tank, is blocked as long as the heat pump is operating. Thus, it starts only if the heat pump is blocked for any reason. CTC EcoZenith I 550...
- Page 17 An air/water heat pump could then be used to give the ground longer time to recover and give the system increased effect. Remember that only one heat pump can be connected via the diverting valves and charge hot water in the upper tank. CTC EcoZenith I 550...

Page 69: Fault Tracing/Appropriate Measures
Fault Tracing/Appropriate Measures The CTC EcoZenith I 550 is designed to provide reliable service and high comfort and also to have a long life length. Here are some tips that may be helpful if any operation errors occur. Should a fault occur, always contact the installation engineer who did the installation. - Page 70 The fault is not in the CTC EcoZenith I 550, and the problem can be easily rectified by replacing the mixer with a soft-closing one. In the case of noise from hard closing dishwashers and washing machines, this can be rectified with a pressure surge damper, which is also a viable alternative to soft closing taps/mixers.
