Page 6: Heating Curve
Heating curve The heating curve is a central part of the product’s control system. It is the heating curve which determines the temperature requirement for your property at different outdoor temperatures. It is important that the heating curve is correctly adjusted, so 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 different settings of the Inclina- tion. The gradient of the curve shows which temperature the heating system requires at different outdoor tempe� ratures.

Page 27: Some Operation Data
Some operation data ◗ Compressor: 5°C between start and stop. The compressor stops on desired value and starts on a 5°C lower temperature. ◗ The desired value of the heat pump is 5°C higher than the desired value of the primary flow down to 35°C heat pump temperature. -
Page 28: 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 29: Fault Tracing/Suitable Measures
Fault tracing/suitable measures CTC EcoHeat is designed to provide reliable operation and high levels of comfort and in addition 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 30 Load monitor (no function on single phase heat pumps) EcoHeat 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 overloaded, an electrical step is disconnected from EcoHeat. 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.

Page 33: Installation
Installation This chapter turns to you who are responsible for the necessary installations in order to give the EcoHeat such an operation as the house owner demands. Take time going through functions, controls, knobs and settings together with the end user and answer eventual questions. - Page 34 Principal sketch for pipe connection Here the principal connection of the heat pump to the heating- and DHW-system of the house is shown. Different facilities and systems may look different e.g. single or double pipe systems, which may make the completed installation look different. Connection of the brine circuit, see “Connetion of the brine system”.
- Page 35 Non-return valve and safety valve boiler Mount the non�return valve to the incoming cold water connection. The safety valve of the boiler is mounted by the manufacturer. The waste pipe must be connected to the draining gutter directly, or if the distance is more than 2 m, to the waste funnel. The waste pipe must lean towards the draining gutter.

Page 36: Connection Of The Brine System
Connection of the brine system Installation and connection of a brine system, i.e. collector for rock or ground, should be carried out in accordance with relevant regulations by a trained technician. Be extremely careful that no dirt enters the collector hoses, which should be flushed clean before connection. - Page 37 Valves Fit the valves as shown in the diagram at the bottom of this page. To allow service to be carried out on the cooling unit, shut off valves should be fitted both to the incoming and outgoing connections. Fit valves with bifurcation so that you can fill and bleed the collector circuit. Bleeding There is to be no air in the collector circuit.
- Page 38 Post installation check of the brine system After a few days, check the fluid level in the tank. Fill if necessary. Close valve �4) and �9) when filling. Level vessel The level vessel, which is included with the delivery, should be fitted to the incoming line from rock or ground, at the system’s highest point.

Page 39: Electrical Installation
Electrical installation Installation and change over of heat pumps should be carried out by a qualified electri- cian. All wiring should be installed in accordance with relevant regulations. The boiler is internally connected by the factory and set for 6 kW electrical power output. It has equal phase loading on all power steps. - Page 40 Connecting the primary flow sensor Fit the sensor to the primary flow pipe, ideally after the circulation pump.

Page 43: First Start
First start When EcoHeat is delivered, the compressor is blocked to avoid it being unintentionally started. The heat pump can be installed and be started before the brine circuit is brought on line. EcoHeat can also be started, without a room sensor having been fitted. The graph then regulates heating. -
