Emergency hot water (using the samsung controller)

🚨 Samsung Heat Pump – Emergency Hot Water (Immersion Heater)

If your Samsung heat pump develops a reoccurring fault and you can’t get hot water, you can temporarily use the immersion heater.

⚠️ Important:

• Only use the immersion if your heat pump is not providing hot water.
• The immersion is inefficient and will increase your running costs.
• This should be a temporary measure until an engineer attends.

Step-by-Step Guide

1. Enter Service Mode

• On your Samsung controller, press and hold the UP (▲) and DOWN (▼) arrows together for ~5 seconds.
• The screen will change to Service Mode.
• (This can be fiddly – you may need to try a few times.)

2. Enter the Service Code

• The screen will prompt you for a code.

  Enter 0202:

  • Use the Right (►) arrow to highlight the digit you want to change.
  • Use the Up (▲) arrow to increase the number.
  • For code 0202 → change the 2nd and 4th digits to “2”.
• Once the code is correct, press OK to enter the service menu.

3. Find the Booster Heater Menu

• Press the Down (▼) arrow until you find Self-Test Mode.
• Press OK to enter.
• Press the Down (▼) arrow again until you find Booster Heater Menu.

4. Turn Immersion ON

• Press the Right (►) arrow to change the Booster Heater setting from OFF → ON.
• Leave the screen on this menu.
• The immersion heater will now run continuously to provide hot water.

✅ Summary

• Immersion ON = hot water backup while your heat pump is down.
• Use only as temporary backup.
• Running costs will be higher while using immersion.
• Contact your installer/engineer to investigate the heat pump fault.
