Commissioning and operation
Programmable functions:
PF name: Laundry ring sensing
- Residual moisture sensor is used to detect a tangled laundry ring.
The programmable function can activate or deactivate this process.
Options:
Option 0: => not active
Option 1: => active
Hoffmann GTZ KDS

20.

Commissioning and operation
Programmable functions:
PF-Name: Overloading
- The load size is deduced from heating parameters in the drying cycle.
This programmable function can activate or deactivate this process.
Options:
Option 0: => not active
Option 1: => active
Hoffmann GTZ KDS
22

21.

Commissioning and operation
Programmable functions:
PF name: Cooling water inlet
- A lack of water inlet during the drying cycle stops the condenser from cooling
and causes a build-up of fluff. This results in higher energy consumption and an
accumulation of fluff in the condenser.
Options:
Option 0: => deactivated (when no cooling water detected > display)
Option 1: => active (when no cooling water detected > display + programme termination)
Hoffmann GTZ KDS

Commissioning and operation
Programmable functions:
PF name: Laundry ring protection
- Max. final spin speed should be limited in composite washing
and drying programmes to reduce probability of laundry tangling
(not in thermo-spin).
Options:
Option 1: 1200 1/min
Option 2: 1100 1/min
Option 3: 1000 1/min
Option 4: 900 1/min
