Figure 9. Keypad

• prog: by entering the user password, it is possible to set the following parameters:

- Setpoint limits

- Setpoint change parameters

- Enable double setpoint

- Regulation parameters

- Start-up and shutdown parameters

- SoftLoad parameters

- Hot water start parameters

- Ambient lockout parameters

- Unit Limitation

- Fan Quiet Mode parameters

- Main pump timing

- Enabling of digital and supervisory inputs

- Time scheduling

• set: it allows to modify the setpoint value within the limits previously set up in the program

• Date and time setting

• I/O: Input/output display and corresponding circuit functions

• (=print): print (not available)
