A warm welcome
Congratulations!
Your home is tted with a unique renewable heating technology, allowing you to benet from lower running costs and a
more even temperature throughout your home.
An air source heat pump collects and utilises thermal energy from the outside air to heat the home and provide domestic hot
water. It does this in the same way that a fridge extracts heat from its inside. It can extract heat from the air even when the
outside temperature is as low as -20°C. The heat generated can be used to warm water for radiators, underoor heating
systems or provide domestic hot water in your home.
The process is simple, eective and entirely renewable and has been developed specically for use in the UK and Irish
domestic housing markets.
In this guide we’ll explain how Aeromax generates heat for your home and how to use your system in the most ecient way.
Your Aeromax Plus Air Source Heat Pump
Your Aeromax Plus air source heat pump is designed to heat your home and to provide domestic hot water (DHW). Normally
your installer will have ensured that your heat pump has sucient heating output to provide these services without any
supplementary heating being required.
You’ll nd your Aeromax Plus unit close to a wall outside your property. It can also be mounted o the ground.

How does it work?
Aeromax Plus Air Source Heat Pumps provide thermodynamic heating by means of a vapour compression cycle. In the same
way that a fridge uses refrigerant to extract heat from the inside to keep the food cool, air source heat pump extracts heat
from the outside air, and uses it to heat the home through radiators, underoor system or provide domestic hot water. It can
extract heat from the air even when the outside temperature is as low as -20°C.
Every air source heat pump has four
main parts:
1. evaporator
2. compressor
3. condenser (heat exchanger)
4. expansion device
Although Aeromax Plus is powered by electricity, when it is installed and designed correctly can often result in the system
costing less to run than systems heated by oil, LPG, electricity or coal. Your heating costs will depend on how you use your
heating or hot water and the temperature of your radiators. Aeromax Plus is cost-eective to use all year round, but you can
ensure it is at its most ecient by running your radiators or underoor heating at lower temperatures.
How do I use it?
The Aeromax Plus heat pump is designed to operate with a standard heating time switch and programmable room
thermostat, providing space heating or DHW according to demand. The unit has two modes of operation: one for space
heating through underoor heating or radiators adjustable between 35°C and 55°C and a second for DHW preset at 60°C.
We recommend that you review the electricity taris from all suppliers in your area and select one that will give you the
optimum economy in relation to your lifestyle and heating demand. Timings appropriate to your heating and hot water
demand and to the selected tari should be programmed into the controller.

Internal Heating
Outside Air
(1) The evaporator collects heat from
the outside air, which is then drawn
into the unit by the fan through the
evaporator ns and expelled through
the front grille. The evaporator has
liquid refrigerant passing through
it, which is at a considerably lower
temperature than the outside air,
therefore the air gives up its heat to
the refrigerant, which then vaporises.
(2) This preheated vapour now
travels to the compressor where it
is compressed and upgraded to a
much higher temperature.
(3) The hot vapour now enters the
condenser where it is surrounded
by water from the heating system.
The heat is given up to the cooler
water and the now cooler refrigerant
returns to its former liquid state but
still under high pressure from the
compressor.
(4) This high pressure is then released
by passing the liquid through the
expansion device and from there it
returns to the evaporator and the
cycle starts again.

Heating and Domestic Hot Water system controls
Your heating system is controlled by a programmable room thermostat that allows you to choose when to have your heating
on and what temperature it should be when it is on. A time switch allows you to choose when you want to make hot water.
The programmable room thermostat controls the temperature of the main living area while thermostatic radiator valves
control the temperatures of the radiators in other rooms.
The Aeromax Plus radiator system works at a lower surface temperature than traditional central heating. This means that your
radiators will take a little longer to warm up your home but will give you a more even comfortable temperature.
Normally your installer will have ensured that your radiators are correctly sized for operation with a heat pump. The heat
pump supplies Domestic Hot Water at between 50ºC - 55ºC. This is stored in the special hot water cylinder provided with your
heat pump to ensure that you always have hot water on tap. The temperature of the stored hot water is controlled by the
cylinder thermostat and you should set this at a level which gives you hot water at a temperature which suits you.
Kingspan recommend that the hot water cylinder thermostat is set between 50/55 degrees C. This will save energy and limit
any unnecessary cycling of the heat pump. The cylinder immersion heater should be set at 60ºC and used to heat the stored
hot water to 60ºc once a week (see hot water table below for recommended timings).
Setting your heating
The programmable room thermostat lets you choose what times you want the heating to be on, and what temperature it
should reach while it is on. It will allow you to select dierent temperatures in your home at dierent times of the day (and
days of the week) to meet your particular needs. We recommend that you set your hot water time switch to heat the hot water
for 1½ to 2 hours before you require it rst thing in the morning, or later in the day. You should set the home heating to come
on after the hot water.
The hot water system and the radiator system cannot run at the same time. If the system requests hot water, the radiators will
turn o until the water heats up.
Typical winter settings for the programmable room thermostat and hot water time switch are illustrated below.

During severe weather conditions where outside temperatures fall below zero it may be necessary to leave the heating
controls on for longer periods when utilising your air source heat pump. This is due to the lower ow temperatures used in
this style of system, which is dierent to that of a fossil fuel boiler.

*Immersion heater: Please use your immersion heater for 1 hour per week after the suggested time indicated. It may be
necessary to utilise your hot water cylinder immersion heater more often in sever winter conditions.

Thermostatic radiator valves (TRV’s)
Some of your radiators have thermostatic valves which allow you to vary the temperature in dierent areas of your home.
You may, for example, prefer to keep your bedrooms cooler than your living room. With underoor heating, the house
temperature is normally controlled by the room thermostat alone. The Aeromax Plus system typically requires at least one
radiator (usually located in the same location as the room thermostat) to remain “open loop” with no thermostatic radiator
valve tted.
Automatic defrost
When moist air comes into contact with the Aeromax Plus’s evaporator, it will ice up in much the same way as ice builds up in
your refrigerator. Defrosting the evaporator is a normal part of the Aeromax Plus operation in colder weather and normally
takes place for about 4 minutes per hour. When defrosting, the fan will stop and water vapour may be seen rising from the
heat exchanger. This is normal and is not a cause for concern.
Safety precautions
1. Do not stand on the heat pump for any reason.
2. Do not allow children to poke sticks or other objects through the front grille into the fan as this could cause
injury and will damage the fan.
3. Outer panels should only be removed by a qualied service engineer.
Servicing
We recommend that an annual service of the Aeromax Plus air source heat pump is carried out, should you require further
details on service packages please contact us. You are advised to check occasionally that there is no debris around the heat
pump which may get drawn into, or obstruct, the fan unit.
Trouble shooting
The diagnostic indicator for the air source heat pump will be located indoors in a visible place. The green lights shows that
the power is on to the heat pump. The red alarm light will ash in the event of a problem. If this occurs count the number of
ashes between pauses and use the fault code table to determine the fault.

System test
The error code can be identied from the ashing LED using the following table. In the case of more than one error, the error
with the highest priority will be displayed until it is resolved. In the case of an error the LED ashes a numbers times equal
to the error code at a frequency of 1Hz and then remains o again for 6 seconds. If the error code has 2 digits, the ashing is
interrupted for 2 seconds between the rst and second digits.
Example: error 23: 2 ashes of 1 second each. O for 2 seconds. 3 ashes of 1 second each. O for 6 seconds. The cycle repeats
until the LED turns o because the problem is resolved or if an error with higher priority occurs.
To reset the unit after an error has been cleared turn o the mains supply for 10 seconds and turn on again.
