. In some cases the time constant of the sensor,
or noise, could cause the display to jump enough to be unreadable. A setting of 2
is usually sufficient filtering (2 represents approximately a 1 second time
constant). When the 0.1 degree resolution is selected this should be increased to
4. If this value is set too high, controllability will suffer.

. If the analog
signal fails, the control will display the error message
C H E C r S P t
and
revert to the
S P 1
local value.
