Our PE1 pellet central heating system with a heating capacity of 20 kW, which replaced an oil-based system from the 1980s in 2023 has a number of settings and parameters that can only be accessed with the appropriate passwords.
Many models of various heating solutions from Fröling have the same access codes, even significantly older ones. Just give it a try; apart from the code being rejected, not much can happen. The existence of these codes is an open secret, and I wanted to compile all the ones I know of here.
You can change the operating level at any time by entering the appropriate code. You should be careful with the newly accessible settings and, if in doubt, consult service personnel. To change the settings, simply tap on the “user icon” in the main menu:
Here are the different codes:
| Operating level | Code | Photo of the main menu | Photo of the control panel |
|---|---|---|---|
| Child safety lock (Kindersicherung) | 0 |  |  |
| Customer (Kunde) | 1 |  |  |
| Service | -7 |  |  |
| Installer (Installateur) | 543 |  |  |
| Internal (Intern) | -127 |  |  |
