•
Numeric values are expressed as 16
-
bit signed binary (two
’
s complement
for negative values).
Note
1.
These parameters can be written while auto
-
tuning is being executed.
2.
The following settings are not possible
Heating output variable lower limit > Heating output variable upper limit
Cooling output variable lower limit > Cooling output variable upper limit
3.
The default is 0008 hexadecimal (0.8
°
C) when the temperature unit is de-
grees Celsius, and 000F hexadecimal (1.5
°
F) when it is degrees Fahren-
