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 notice.
1
The radiator temperatures are lower than normal and will alter as the outdoor
temperature changes. The colder it is outside the warmer the rads and vice versa.
This function is automatic and is designed to save you money. At their hottest they
will reach 50C. If you would like a constant radiator temperature this can be set by an
engineer but it will increase your run costs by up to 25%.
2
The system is designed to run continuously in cold weather, turning the system on
and off will make the house uncomfortable and will increase your run costs. The most
efficient way to run this heating system is to leave it running at the set temperature 24
hours a day in winter time. If you turn off the heating and let the house get cold (less
than 17C) it will take a very long time to warm back up to a sensible temperature.
Your systems have been set up to be simple to operate.
The Samsung controller looks like this, you should not use this or
press the buttons on it, it is for commissioning and making settings
to the system only.
You should see 0.0C on the screen this means the unit is under
external control from a room thermostat.
If the system goes into fault, the screen will show a number at the
bottom starting with E, for example E911 – A00
The engineer will want to know this number when you call him.
Heating
Control of the heating is by your wall mounted thermostat, not the Samsung controller; you
need to read the instructions for this thermostat as its field supplied. The boiler will run when
told to by the thermostat. DON’T set the room temperature too low, the heat pump takes time
to recover the house temperature, as a rule don’t set the temperature more than 2 degrees
below your normal set temperature when you go out of the house or it will take a long time to
recover.
To switch off the heating in summer set the temperature down to 16C to avoid the heating
starting up.
To control the temperature in your rooms please use the radiator valves.
Hot water
Your system will keep the hot water cylinder hot at all times automatically, as you use the
water the heat pump will constantly top up the cylinder. A cold cylinder should be reheated
within an hour. An anti-legionella operation will be completed at a predetermined time every
Tuesday morning. The hot water will be hotter on a Tuesday morning than the rest of the
week.
