Homeowner’s User Instructions
Introduction
The Ecodan air source heat pump extracts thermal energy from the outside air and transfers this into a property
in the form of hot water as a conventional heating system does. The Ecodan will provide space heating (through
radiators or under floor heating) and domestic hot water (taps, showers, etc). Domestic hot water always takes
priority over space heating.
The Ecodan Aerocyl-me package is controlled by conventional heating system control equipment. A two channel
time clock for ON and OFF periods, a cylinder thermostat for domestic hot water temperature and a room
thermostat for space temperature.
To optimise running costs it is advisable the homeowners seek the cheapest possible electricity tariff. An internet
search facility like www.uswitch.com will be able to help.
The homeowner will need to control the Ecodan Aerocyl-me differently to a conventional gas boiler. The use of
controls is paramount in achieving low running costs. Although electricity prices are higher than gas or oil, the
efficiency of the system means that it requires less energy to supply the same heating demands, thus producing
cheaper energy bills. Compared to regular electricity bills it will look higher than usual, but the homeowner
should be aware that this bill incorporates heating that is usually achieved though gas or oil.
Please note that heat pumps provide lower flow temperatures to radiators than a conventional gas boiler.
Rather than the radiators turning on/off locally as with a gas boiler, heat pumps provide a more consistent lower
flow temperature which allows for more efficiency and greater comfort.
Warnings
•
•
•
•
•
Don’t allow anyone to interfere with the outdoor unit.
Don’t push any object through the grille area, there is a fast turning fan which could be damaged.
Don’t place objects too close to the outdoor unit.
Don’t ever cover the outdoor unit, air needs to circulate freely around the unit.
Do be aware that ice may form in the winter period on the ground close to the outdoor unit. Please take
particular care.
• Do ensure your installer includes anti-freeze (Alphi-11 or similar), 25% concentration into the heating
circuit to prevent icing in the winter.
• Do complete your guarantee registration card and return to the manufacturer. If you do not complete
and return the registration card the product will only be under guarantee for 12 months.
• Do take the installers contact details in case you need attention in the future.

The homeowner should know:
How to switch on power to the Ecodan Aerocyl-me
This will be located inside the property near the mains power switch, it needs to be switched on. The outdoor
unit does not needed to be touched.
How to switch off power to the Ecodan Aerocyl-me
This will be located inside the property near the mains power switch, it needs to be switched off. If the homeowner
is away from the property for several days only switch off the indoor switch. The outdoor unit does not need to be
touched, do not switch off at any time.
How to set the radiator temperature
Thermostatic radiator valves control the temperature of the radiator by a built-in sensor, which automatically opens
and closes the flow of water into the radiator, maintaining the room at the pre-set temperature. A manual valve can
only control the temperature of the radiator regardless of the room temperature. If your property has thermostatic
radiator valves, it is recommended that they are fully opened in occupied rooms. The Ecodan works by varying the
flow temperatures to radiators depending on room thermostat and outside temperature.
How to set indoor temperature
The room thermostat is needed to set the indoor temperature. Refer to pages 7-8 for user instructions.
How to set the timer
The 2 channel time clock is needed to switch heating and hot water on/off. Refer to pages 9,10 and 11
for user instructions.
How to switch to constant use
Constant running dictated by the 2 channel time clock as this controls on/off periods. Refer to pages 7-8 for user
instructions.
Time clock pattern setup
Each channel on the time clock should be programmed to meet the demands of the home occupier in the
most efficient way. Hot water will take priority over heating.
For example:
If a homeowner wakes up in the morning and wants a shower at 7am and the property takes an hour to raise to
the required room temperature then both channels should be set to 5am, as the vessel will take approximately
one hour to achieve temperature before switching to space heating. Some electricity tariffs have cheaper off-peak
tariffs (early hours of the morning) that can be used for heat-up times. Always check your electricity tariff by using
www.uswitch.com.
If the homeowner does not require hot water again until later in the evening then the time clock should be
programmed to heat up approximately one hour prior. This is the most efficient pattern to use rather than
maintaining a high storage temperature constantly.
During cold periods the Ecodan will switch into a defrost mode occasionally. At this point the Ecodan will
stop producing hot water for inside the dwelling. It will only be for a few minutes and will not cause radiators
or under-floor heating to suddenly stop, nor will the heat of the cylinder radically drop. During this process
steam may rise from the outdoor unit. This is a perfectly normal process, it is an automatic procedure.
To maintain the efficiency of the Ecodan a weather compensation mode is activated (by the installer). When
the outside temperature is colder the flow temperature to the radiators/under-floor is hotter. When warmer
outside radiators will be less. This weather compensating curve is pre-set by the installing engineer. Lower
flow temperatures mean higher efficiency.

Troubleshooting
Fault
Possible Cause
Solution
Water does not heat up well
Ecodan may not be working
to its highest capacity.
Make sure that there is plenty
of space around the outdoor unit
so air can flow in and out.
Filter may be dirty and needs
to be cleaned.
Cleaning of this filter should be
carried out by your installer.
During the heating mode, water
may form and drop from the heat
exchanger on the outdoor unit.
No solution necessary, this will
not effect the performance of
the Ecodan.
During the defrosting mode, water
on the heat exchanger or the
outdoor unit evaporates and water
vapour may be emitted.
No solution necessary, pay
attention in icy conditions.
System may be switched off.
Switch on unit and continue
operation as usual.
Hot water used may have exceeded
capacity of cylinder.
Tank will automatically fill up as
water is used but will take time to
heat up. This is dependent upon
the size of the cylinder.
Temperatures set are too low.
Temperature parameters are too
low and need to be set by your
installer.
Hot water provided but no heating
Time clock has been programmed
incorrectly.
Refer to pages 9, 10 and 11 for
time clock instructions and set
desired times for each function.
Heating provided but no hot water
Time clock has been programmed
incorrectly.
Refer to pages 9, 10 and 11 for
time clock instructions and set
desired times for each function.
Heating does not work at
specific times
Time clock has been programmed
incorrectly.
Refer to pages 9, 10 and 11
for time clock instructions
and set desired times.
Heating and hot water are
active at different times during
the weekend
The programmable room
thermostat has 5/2 split function
to create different settings for
the weekend.
Refer to pages 7 and 8
for programmable room
thermostat settings.
Room becomes too hot when
heating is operated
Programmable room thermostat
set too high.
Refer to pages 7 and 8 and
lower temperatures.
Heating is not needed during
summer months and should be
switched off.
Refer to pages 9, 10 and 11
for time clock instructions to
stop heating mode.
Water or vapour is emitted from
the Ecodan unit
Cold water at hot taps
If these options can not rectify the problems then please contact your local installer so a qualified engineer can fix
the problem. Any work carried out by the homeowner will cause the warranty to be void.
