Changing of heating time limitation
The heating time limitation of the control unit is limited to 99min at the factory. This can be extended to up to
24 hours by setting the jumpers described below. The jumper set is available as an accessory under the order
number O-JUMP.
Tip: it is only possible to set the heating time to the precise minute up to a running time of 99min.
From 99 min to 9.9 hrs, the running time can be exactly set to 0.1h (6min). Beyond this, only in 1 hour
steps.
Tip: the heating time limitation may be extended to a maximum of 6 hours for domestic use. For
heating time limitations >6 hrs, the relevant regulations of EN60335-2-53 must absolutely be heeded.
