On entering function [78] the function display will read 78.
The upper display shows 30.00 mV setting.
Enter the exact mV as measured by the millivolt meter.
The main display will flash all zero’s. During this period the controller is
checking calibration so do not alter the mV reading. When the flashing
stops, the calibration is complete and the controller will return to
“RUN” Mode.
To increment the flashing digit press the button
To advance to the next digit press the button
To save the mV setting and start calibration press the button
37
Function [79] does not control any other function
On entering function [79] the function display shows 79.
The zone display shows blank.
The upper display shows 0.
By advancing the flashing digit the operator can select
[0] to return with no changes
[1] to [6] to start profile on any one zone 1 to 6
[7] to start profiles on all enabled zones 1 to 6
To increment the flashing digit press the button
To start profile and return to “RUN” mode press the button
