Page 3: Heat Pump Overview
Heat Pump Boiler Overview A heat pump works in a similar way to that of a domestic fridge, although in re- verse. Heat is moved from one source to another. The outdoor based Ecodan exploits the physical properties of a refrigerant to heat water that flows into the dwelling to the radiators/ under-floor heating and the hot water cylinder for hot water usage. -
Page 4: How A Heat Pump Works
How a heat pump works The heat pump essentially works the same way as your refrigerator but in reverse. The Ecodan® is hermetically sealed (no refrigeration piping involved) with R410A refrigerant, the cycle it completes to produce heat is known as the vapour- compression refrigeration cycle: The first phase begins with the refrigerant being cold and low pressure. -
Page 5: Room Thermostat
Room Thermostat The aim of the thermostat is to control the room temperature, although one model used will vary from one home to another its function will not. This is the homeowner’s connection to the heat pump boiler. The room thermostat and the time clock (both supplied by 3rd party manufacturers.) are the 2 main con- trols for the home owner to use. -

Page 12: Heating Set-Up
Heating Set-up (Heating Eco Mode) Whilst heating a property the ‘eco heating’ is the recommended mode to use; this setting is a heating function with weather com- pensation. This function sets the target temperature depending on the outdoor temperature. The buttons on the controller are represented by letters explained on page 10. -
Page 13: Recommended Settings
Recommended Settings The controller has settings pre-installed that will provide adequate hot water and heating, but they can be amended using the instructions in the first two sections. The temperatures that should be used are as follows PAR-W21MAA recommended flow temperatures Factory Settings Recommended Hot Water... -
Page 14: Available Modes
Available Modes There is a selection of modes on the controller that the end user can choose for set-up purposes; please note that some of these may have been removed or disabled for use with the Ecodan® unit. From the normal display it will always skip progress to ‘water temp heating’, each press of button E will skip to the next available mode. -

Typically it will take about one hour to recover a 150 litre storage tank from cold. -
Page 18: Running Costs
Running Costs Due to the fact that most houses will vary in size, occupants, electricity supplier and desired heating requirements it is impossible to give a completely accurate guide to electricity usage with a Ecodan® Air Source Heat Pump, but providing the homeowner has followed the guidelines in this manual savings will be made over conventional gas/ oil boilers. -
Page 19: Time Clock Set-Up/ Patterns
Time clock pattern set-up The Flow Temperature Controller time clock patterns must be set to accommo- date a hot water priority system. For example: The hot water heat up cycle should have an ON/OFF time approximately 1.5 hours apart (dependent on the cylinder capacity), this time should be outside the time period where space heat- ing is required as it will not be available while hot water is taking place. -
Page 20: Domestic Hot Water Immersion Heater
Domestic Hot Water Immersion Heater As the Ecodan® ASHP can heat domestic hot water cylinder to 55°C. Pasteurization should be carried out by an immersion heater situated in the body of the hot water cylinder. The heater should be timed to operate after the Ecodan has completed a hot water cycle thus completing the lowest temperate rise possible (from 55°C to 60°C). -
