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 Plus-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 Plus-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.

Ecodan
This will be located outdoors (most likely to be in the garden)
facing away from the property. The air is sucked into the back
and used to heat the refrigerant that is sealed within the unit.
Cold air will be expelled from the front of the unit when the
Ecodan is operating. The homeowner does not need to make
any adjustments to this element of the system.
Always ensure the front and back are clear of obstructions.

The homeowner should know:
How to switch on power to the
Ecodan Aerocyl Plus-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 Plus-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.

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.
Troubleshooting
Fault
Water does not heat up well
Water or vapour is emitted from
the Ecodan unit
Cold water at hot taps
Hot water provided but no heating
Heating provided but no hot water
Heating does not work at
specific times
Heating and hot water are
active at different times during
the weekend
Room becomes too hot when
heating is operated
Possible Cause
Ecodan may not be working
to its highest capacity.
Filter may be dirty and needs
to be cleaned.
During the heating mode, water
may form and drop from the heat
exchanger on the outdoor unit.
During the defrosting mode, water
on the heat exchanger or the
outdoor unit evaporates and water
vapour may be emitted.
System may be switched off.
Hot water used may have exceeded
capacity of cylinder.
Temperatures set are too low.
Time clock has been programmed
incorrectly.
Time clock has been programmed
incorrectly.
Time clock has been programmed
incorrectly.
The programmable room
thermostat has 5/2 split function
to create different settings for
the weekend.
Programmable room thermostat
set too high.
Heating is not needed during
summer months and should be
switched off.
Solution
Make sure that there is plenty
of space around the outdoor unit
so air can flow in and out.
Cleaning of this filter should be
carried out by your installer.
No solution necessary, this will
not effect the performance of
the Ecodan.
No solution necessary, pay
attention in icy conditions.
Switch on unit and continue
operation as usual.
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.
Temperature parameters are too
low and need to be set by your
installer.
