bargraph shows the actual (ramping) set point value and the digital display shows the target set
point value.

Control Set Point
['SPLO' to 'SPHI' – see Section 5.5]
Adjustable in Local Control Only
Control Output
[0 to 100% (digital/relay outputs),
–10 to 110% (analog outputs)]
Adjustable in manual mode only. With on/off control
selected, 0% = control output off, 100% = control
output on. In manual mode, intermediate values can
be selected. These use 'time proportioning' with a
60s cycle time, e.g. 25% = 15s on, 45s off.
Remote Set Point Ratio
[0.001 to 9.999]
Remote set point value =
(ratio x remote set point input) + bias
