Page 3: The Outdoor Unit (Boiler)
The Outdoor Unit (Boiler) It is important to situate the unit within an open area with a good airflow, it is a good idea to choose a location that is not going to be blocked by plants, animals or anything else that may obstruct the airflow. Another factor to take into account is the mounting surface, make sure it is a flat, solid surface capable of withstanding the weight of the heat pump. -

Multi Fuels Buffer Tank with coil Pump HP Pump Z1 Stat set to 55°C Other sources into coil Operation • The temperature of the hot water is controlled with the cylinder sensor and the supplied controller. • The controller has a built in time clock control and has both daily and weekly sterilisation functions for legionella. • The system is able to be setup as open vented or pressurised. • The coil within the cylinder must be designed for use with a heat pump with a surface area of at least 2.5 m². • A guideline for sizing the cylinder would allow 55 litres of water per person each day. • It is recommended that the heat pump is sized so that it is able to reheat the cylinder within an hour. • As with most cylinders, it is possible to connect a PV system to the immersion heaters to reduce costs. A battery storage system is also a great way to help with this. • The heating system is controlled via a thermostat / time clock that is wired back to the internal control board (MIM). • There is not a limitation to the number of heating zones that can be connected to this setup. • This setup shows one heating zone. • Each heating zone will be controlled by its own thermostat or timer, this will operate it’s own zone valve which will then control the pump. This in turn will create the run signal for the heat pump to operate in heating mode. -

Remote controller The Samsung control is usually installed in close proximity to the control box and is mostly used for commissioning purposes. To connect this to the control board you will need a 2 core 0.50.75 mm 2 core flex that connects to F3 & F4 in the controller to F3 & F4 on the control... -
Page 24: What Comes With The Unit
What comes with the unit? The first thing that you will see when you open the box (unless you open it upside down) should be the sensor cables. The blue sensor cable is used to measure the temperature inside the cylinder and connects into a yellow socket on the control board labelled CNS042. The sensor should be located in the top half of the cylinder above the immersion heater. -
Page 25: Start-Up Procedure
Start-Up Procedure Before connecting the heat pump to the system, a thorough system flush is highly recommended in line with the Building Regulations for England and Wales, Part L, 2006. Using a power flusher, fill the system with a mixture of water and 25-30% glycol, there is no pressure sensor in the unit so it can operate from open vented to 3 bar max. -

Page 32: Handover Of The System
Handover of the System Leave the following pages with the Homeowner 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. The installer of the system should have provided you with a room stat to control the temperature, or if you have underfloor heating you will have a stat in each room. To turn on your heating, you only need to turn up your thermostat. To turn of your heating, turn it back down. 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. Weather compensation and water law: The temperatures of the radiators will not be what you may be used to if you used to have boiler, as well as this the heat pump will run in what is known as weather compensation mode. -
Page 33: General Advice
Hot Water The temperature of the cylinder is controlled by the Samsung controller, this is setup to maintain the temperature of the water between 43°C and 50°C. As hot water is used, the heat pump will be constantly monitoring the temperature inside the cylinder, the hot water heating has priority over space heating. If the cylinder falls by 5°C from the setpoint, the heat pump will automatically switch to hot water heating. -
Page 34: Warranty Registration
If the installer wishes to do so, they can offer a warranty to you/end user that covers the whole system. The standard warranty terms for the Samsung heat pump is 3 years, if the installer is a Samsung certified installer then the warranty terms are 7 years. -

Page 37: Problems And Faults
One thing to check is that the heat pump turns off when all the stats are turned down or off. When the unit is set up it should have AU on the Samsung controller meaning that the heat pump will only operate when it receives a run signal back to B22 or B24 in the control box. - Page 38 Dead remote controller but red lights are on the indoor PCB On first startup you will notice two red LEDs light up, after around 4 minutes the screen will light up. If the controller hasn’t started after around 4 minutes and the control board has the red LEDs lit up, there is a small brown eeprom PCB plugged into the board.
