Handover of the System
Please search YouTube for Freedom Heat pumps Handover Video for Samsung Heat Pump for Homeowners
Thank you for buying a Samsung EHS heat pump system, your Samsung heat pump heats the house and hot water cylinder
much like a normal fossil fuel boiler, however there are a couple of differences which you should take notice of.
Your installer should have provided you with a room thermostat if you have radiators or a thermostat in every room if you have under
floor heating. The installer will be able to run through the operation of your stats with you. The heat pump will operate from the signal
sent by these stats back to the heat pump, please do not use the Samsung controller to control your heating.
Once the unit starts up it will take time to get to temperature, it is not instant. Within 10 minutes you should feel the radiators beginning
to warm up. Although it may take a few days to have everything to the required temperature, please do not switch your stats off during
this period.
Weather compensation and water law
The radiator temperatures will be lower than you are used to with a gas or oil boiler. To add to this, we run them in a weather
compensation mode, this means that the unit measures the outside temperature and adjusts the radiator temperature to suit.
The colder it is outside the warmer the rads will be and vice versa. This function is automatic and is designed to save you money. In very
cold weather the radiator will be at their hottest, they will reach 50°C.
Running your machine efficiently
It is very expensive to heat the house up from cold, with a heat pump the best advice is to maintain the house at as close to constant
temperature as possible all the time.
Please DON’T set the room temperature too low when you leave the house, ideally drop it no more than 2 degrees below your normal set
temperature when you go out or it will take a long time and a lot of money to recover.
To switch off the heating in summer set your room thermostats down to 16°C to avoid the heating starting up. Your radiators will have
thermostatic valves on them, you can adjust each room’s temperature with these.

General Advice
The heat pump comes with a Samsung controller which looks like
this, you should not use this or press the buttons, it is used for
commissioning and fault diagnosing the system only.
On Youtube (search for freedom heat pumps) there are videos
showing how to use the controller, faults etc.
Normally the controller will show AU or 0.0c on the left and a tap
in the right hand top corner. This is normal, it means the system
is controlled by external thermostats. If it says 0.0c you can boost
your heating water temp using + or – but it costs more money if its
set above 0.0C
If the system goes into fault, the screen will show a number at the
bottom starting with E, for example E911 – A00. The green light
will go out and a red light will flash. The engineer will want to know
this number when you call.
Please avoid turning the unit off at the power supply especially
in cold weather. If the unit is off and the weather is very cold, it
cannot protect itself and your warranty will be at risk.
If the unit is off and the temperature outside is cold, it will
automatically run the pump for a few minutes to stop freezing.
In extreme weather, below -2°C the water pump will run
continuously, you cannot stop this.
Hot Water
At the top right of the controller you should see a tap with 2 dots, this means your unit is monitoring the cylinder temperature.
The unit it set up to maintain the water between 43 and 50°C all the time.
As you use the water the heat pump will constantly top up the cylinder. The hot water cylinder has priority over the heating, if the
cylinder temperature falls 5 degrees below its set point the unit will automatically switch to heating the cylinder. This should take less
than an hour.
Once set temperature is achieved the unit will go back to heating the house. The hot water cylinder loses almost no heat (1/3 a degree
an hour) if no hot water is used.
If you want to heat the cylinder very quickly you can press the
DHW mode button
, on the right until a bath shows, this will run the heat
pump and the immersion together. Please remember to return the tap with two dots when it is no longer required.
An anti-legionella / disinfection operation will be completed at a 3am every Wednesday morning.
The unit will heat the cylinder with the immersion to 60°C, the hot water will be hotter on a
Wednesday morning than the rest of the week. If legionella is not completed this
e919
will flash on
screen, you need to call an engineer to check it.
If you don’t require 24/7 hot water It is possible to time clock the hot water to reduce costs, the timer video on you tube will show you
how to do this.
