MANUAL CONTROL MODES
SP1.P – Read SP1 output percentage power. (Read only).
hAnd – (off) SP1 Manual percentage power control.
For manual control, should a sensor fail, record typical SP1.P values beforehand.
PL.1 – (100) Set SP1 power limit percentage, 100 to 0% of the duty cycle. Limits
maximum SP1 (heater) output power during warm-up and in proportional band.
PL.2 – (100) Set SP2 power limit percentage, 100 to 0% of the duty cycle.
Limits maximum SP2 (cooling) output power during warm-up and in proportional
band.
SP2 OPERATING MODES
SP2.A – (Cool) Main SP2 operating mode.
Must remain in “Cool” mode properly to operate the cooling system.
If use of the Model 563 Liquid Carbon Dioxide System is not needed, it is
recommended that SP2.A be set as ‘nonE’. The output to the cool valve will be
disabled and will not ‘click’ on and off unnecessarily.
SP2.b – (nonE) Subsidiary SP2 mode: latch/sequence. Non-linear dehumidify
proportional band.
INPUT SELECTION AND RANGING
°°C to °°F conversion - A total of 4 settings must be modified to change scales.
These include hi.SC, lo.SC , unit and ZEro (See Level 3). For these settings
there will be two sets of values in parenthesis. The first one is the °C setting, the
second is the °F setting.
diSP – (0.1) Select display resolution.
hi.SC – (100), (212.0) Sets Sensor full scale. The sensor full scale is also the
upper limit for the setpoint.
Lo.SC – (0.0), (32.0) Sets Sensor minimum. The sensor minimum is also the
lower limit for the sensor set point.
