CYCt Cycle time 0 to 250 seconds
(2) 0 turns OP1 off. This
parameter does not
appear if Valve
Positioner option is
installed.
OPAC Control Action drct - cooling
rEv - heating
(rev) For both PID &
ON/OFF control.
OPLO Output power lower
limit range 0% to 100%, OP1
(0) Set OPLO < OPHI
-100% to 100%,
OP1 & OP2
(-100) If cooling option is
installed.
OPHI Output power
upper limit range 0% to 100%, OP1
(100) Set OPHI > OPLO
-100% to 100%
OP1 & OP2
(100) If cooling option
installed.
OPFL Sensor fail power
preset 0% to 100%, OP1
-100% to 100%,
OP1 & OP2
(0) Set to a value to
safely control the
process in the event
of input sensor
failure.
OPdP Output power
dampening
(filtering) time 0 to 250 seconds
(3) 0 = off
(no dampening) Set
in range of
1 50
to 1 10
of
integral time.
CHYS ON/OFF control
hysteresis 1 to 250
1 or 0.1 degree
(1) Heating side only.
tcod Auto-tune
dampening mode 0 to 4
(0) 0 = fastest response
