Parameters
HAL
and
LAL
intended as the absolute temperature value or
differential in relation to the setpoint.
0
= absolute value;
1
= relative value.
N.B.: In case of relative values (para. Att=1) parameter HAL should
be set to positive values, whilst parameter LAL should have
only negative values (-LAL).
