1. The regulator restores factory settings to the charasteristic
heating curve settings.
2. Eliminates clock functions
3. Restores user and maintenance level settings
4. Selects automatic control for the operating mode
5. Selects the basic regulator for the regulator type.
6. Identifies the connected sensors and assumes which regulating circuits
are in use.
7. Restores factory settings to the tuning values and trend sampling intervals.
8.
lay controls are not in use.
10. Sets alarm Dig 1 (Dig 2, Dig 3) as an assumption into digital inputs.

12. Erases the telephone number and restores the factory settings to the
modem settings.
Original factory settings can be restored with the regulator in the following
manner:
Selects 0…10V for actuator control with a running time of 150 s in H1 and
H2 and the 3-point control for actuator control with a running time of 15 s
in the hot water circuit.
