Cue

Description

SP

Control Setpoint, range from "rL" to "rH".

nnnSoftware key for parameter protection set in Conf mode P18.

A1

Alarm 1 Setpoint, range from Conf mode P2 to P3.

A2

Alarm 2 Setpoint, range from Conf mode P2 to P3.

H1

Alarm 1 hysteresis (deadband) 0.1 to 10.0% of

 

alarm span.

H2

Alarm 2 hysteresis (deadband) 0.1 to 10.0% of

 

alarm span.

Pb

Proportional Band, range from 1.0 to 99.9% of

 

span for heating output, 1.5 to 99.9% of span

 

for heating/cooling output. If Pb = 0, ON/OFF

 

control is enabled and ti, td, C, C2, rC, OLP,

 

OLH and IOL are not displayed.

HS

Hysteresis (deadband) for ON/OFF control

 

(active if Pb = 0), range 0.1 to 10.0% of span.

ti

Integral time (automatic reset), range 1 minute

 

and 20 seconds to 20 minutes and 00 seconds,

 

or if blank integral is disabled.

td

Derivative (rate), range 1 second to 9 minutes

 

and 59 seconds. If 0, derivative is disabled.

CHeating cycle time, range 1 to 200 seconds (30 seconds or greater recommended for relay outputs).

C2

Cycle Time for Output 2 (heat/cool control

 

selected), range 1 to 200 seconds (30 seconds

 

or greater recommended for relay outputs).

rC

Relative cooling gain (for heat/cool) control

 

range 0.20 to 1.00.

OLP

Overlap/Deadzone (for heat/cool) Positive value

 

is amount of overlap; negative value separation

 

between heat and cool Pbs, range -20 to 50% of Pb.

rL

SP minimum value (low limit)

rH

SP maximum value (high limit)

rP

Ramp on setpoint changes, range 1 to 100

 

degrees/minute or blank (step change).

OLH

Output power max. value, range 0 to 100%

 

heating, -100 to 100% heat/cool, limits power

 

continuously (tOL = blank) or on startup per

 

tOL settings.

tOL

Time interval for OLH power output limit, range

 

1 to 100 minutes or if blank infinite. The timer

 

starts if the actual temperature is less than P15

 

(threshold value).
