*) Can only be set when regulation is stopped (r12=0)
**) Can be controlled manually, but only when r12=-1

Factory setting
If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep upper and lower button depressed at the same time as you reconnect the supply voltage
