RESET (Integral) adjusts controller output according to variation (SP-PV) magnitude
and lasting time. Amount of adjustment depends on that value, or the gain. Reset
adjustments are measured according to the number of proportional action repetition per
minute, or the number of minutes during which the proportional action repetition was
taking place.
(4) Control Direction selection button : It is changeable only at STOP mode.

z Reverse : Heating
z Direct : Cooling
(5) FUZZY control selection button
z Selecting to enable or disable fuzzy control.
(6) FAIL-SAFE:
z When analog input sensor type is Voltage/mA(0~10V, 1~5V, 4~20mA..), if input fail
status(Burn out, input high, input low) occurs, the control output become fail-safe value
instead of PID control output.
z Set range: -5.0~105.0%
