General Advice - Samsung 050JXYDEH Installation And Maintenance Manual

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.
Normally the controller will show AU or automatic mode, this means its looking for a
thermostat to tell it when to run.
If the system goes into fault, the screen will show a number at the bottom starting
with E, for example E911 – A00. Normally there is a sun symbol at the top of the
screen, if the unit is faulting the sun disappears. 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.
If the unit is off and the temperature outside is cold, it will automatically run the pump
for a few minutes to stop the unit freezing. In extreme weather, below -2C the water
pump will run continuously, you cannot stop this.
Hot Water
The hot water is supplied by your boiler just as it always was.
