Heating curve The heating curve is a central part of the product’s control system. It is the heating The set heating curve curve which determines the temperature requirement for your property at different is always prioritised. outdoor temperatures. It is important that the heating curve is correctly adjusted, so The room sensor can only call on the mixing that you achieve the best function and economy possible. - Page 7 Examples of heating curves Below you find three charts where you can see how the heating curve changes by differ- ent settings of the Inclination. The gradient of the curve shows which temperature the heating system requires at different outdoor temperatures. Inclination: Prime flow The set value of the gradient is...
- Page 8 Suitable standard values At the time of the installation it is seldom possible to instantly set the heating curve exactly . The values to the right may then be a good starting-point before the more ac- curate adjustment is set. Radiators with small heat emission surfaces require higher primary flow temperatures.

Page 28: Other Information
Other information CTC EcoEl operating temperatures CTC EcoEl operates in the temperature range up to 80°C. When connected with a CTC heat pump, the operation temperature would be 35-55°C, depending on the current heating requirement on the supply line. This is completely normal and is monitored by the control system, which continuously ensures that you are provided with optimal function Indoor sensor... -
Page 29: Operation And Maintenance
Operation and maintenance When the installation contractor installs your new heat pump, you should together with the contractor check that the system is satisfactorily set up. Ensure the installation cont- ractor demonstrates the switches, controls and fuses, so you know how the system works and how it should be operated. -
Page 30: Fault Tracing/Suitable Measures
Fault tracing/suitable measures CTC EcoEl is designed to provide reliable operation and high levels of comfort and in ad- dition have a long lifetime. Below are a number of suggestions and guidelines which can be useful in the event of malfunction. If a fault occurs, you should always contact the installation contractor who installed your unit. - Page 31 Load monitor EcoEl has a load monitor. If the supplied current sensor is fitted, the house’s main fuses are continuously monitored to ensure they are not overloaded. If the fuses are overload- ed, an electrical step is disconnected from EcoEl. The heat pump can be limited where high heating requirement levels are combined with (for example) single phase engine heaters, cookers, washing machines or tumble dryers.
