Fuses (made of ceramic)
A fuse change may only be carried out by trained specialist personnel with the 230 V AC supply disconnected!
The applicable safety regulations and rules must be observed!
The power supply unit for supplying the electronics and all 230 V AC circuits are protected by fine-wire fuses.
To change a fuse, please observe the following overview:
Fuses Value Description Configuration
F1 6,3 A T –
Protection 230 V AC:
Return pump, Return mixer OPEN/CLOSE
F2 400 mA T –
Protection 230 V:
Transformer primary side
F3 630 mA T –
Protection 18 V AC:
internal electronics (transformer secondary side)
F4 2,5 A T –
Protection 12 V AC:
Heating lambda sensor

PTC – Fuses
In addition, self-resetting PTC fuses are used:
Fuses Value Description Configuration
F10 0,5 A +24 V 2
+24 V- Output for digital outputs and analog
inputs:
DI1 X12 WTR-monitoring
AO1 X11 primary air damper
AO2 X10 secondary air damper
These PTC fuses are service-free and may only be replaced by trained specialist personnel!
The PTC fuse remains high-impedance as long as overcurrent is present. The PTC fuse thus protects
continuously until the fault is eliminated or the current is switched off.
When resetting itself, the resistance of the PTC fuse quickly returns to its initial value.
