8.2.1 Changing the Single Point Calibration Offset
OFSt
Starting from

Press the Page key until
OFSt shows on the display.
Press the Up or Down arrow key to display the current calibration offset.
Press the Up or Down arrow key to change the offset value.
The value will then be stored without any further input.

from the Home display and go to
OFS.t directly and enter the password at this point when
the calibration adjustment is required again.
8.3 Dual Point Calibration -
C.CL2
Dual point calibration uses two offset values at two corresponding temperatures to
progressively change the calibration as the temperature increases or decreases. This is a
more accurate representation of how the temperature difference will occur.
Caution! - Do not make
CAL.L and CAL.H the same value as the controller will not work
correctly and could cause your furnace or oven to overheat.
8.4 Changing the Calibration, Low Temperature
– CAL.L
Starting from
CL.St after C.CL2 has been selected.
Press the Page key until
CAL.L shows on the display.
Press the Up or Down arrow key to display the current calibration low temperature.
Press the Up or Down arrow key to change the temperature value.
The value will then be stored without any further input.
Once
C.CL2 has been selected as the customer calibration type, it is possible to start from
the Home display and go to
CAL.L directly (or any of the other settings in C.CL2) and enter
the password at this point when calibration adjustment is required again.
