Option 70.0 - Erase enable (0/1)*
WARNING: If this value is displayed as a ‘2’, the option parameter data has been ‘up-
loaded’ into the unit, ensure all option parameters are set to match the requirements of the
burner to which it is connected. Failure to do so could cause a hazardous condition to occur.
After all option parameters have been checked to match the requirements of the burner to
which it is connected, reset this option parameter to zero to allow the system to operate.
If an attempt is made to operate the system with this option parameter set to ‘2’ a fault will
be generated and the unit will perform a safety shutdown, preventing the burner from fir-
ing.
In order to erase information in memory for a specific profile selection (see option parameter 70.1),
this option must be set to 1. Once the unit has left set-up mode, this parameter will automatically be
reset to "0". If this option parameter is set to 2, see warning above.
Option 70.1 - Erase command (0 – 8)*
When erase enable (option 70.0) is set to "1", this option parameter determines which information
will be erased when the unit leaves set-up mode.
0
- No erase.
1
- Erase profile 1 setpoints.
2
- Erase profile 2 setpoints.
3
- Erase profile 3 setpoints.
4
- Erase profile 4 setpoints.
5
- Erase profile 5 setpoints.
6
- Erase profile 6 setpoints.
7
- Erase profile 7 setpoints.
8
- Erase all setpoints and initialize all option parameters.
All setpoints with the exception of CLOSE SET will be erased for the specified profile combination
of 1-7.
If 8 is selected, all setpoints inclusive of CLOSE SET will be erased and all option parameters will
be set to default values. The unit will be initialized to the same state as when it was shipped. Since
this operation takes some time to execute, a countdown will be given in run mode during the initial-
ization process.
