PARAMETER DESCRIPTIONS

SP = Set Point. Temperature desired to regulate the machine. Can vary
from r1 to r2.
Note
r0 = Differential. Heating: If temperature is ≥ SP then output is OFF. If
temperature is < SP - r0 then output is ON. Cooling: If temperature is ≥
SP + r0 then output is ON. If temperature is < SP then output is OFF.
r1 = Lower Set Point Limit.
r2 = Upper Set Point Limit.
d0 = Heat or Cooling Control. Ht = heating control, Co = cooling control.
d2 = Not used
d8 = Not used.
c0 = Minimum Time for Compressor to be OFF. Minimum time for the
compressor to stop until it can start again.
c1 = Continuous Cycle Time. The remaining time for a continuous cooling
cycle.
c2 = ON Time of fault cycle, during probe error.
c3 = OFF Time of fault cycle, during probe error.
P0 = Selection of Engineering units between F and C.
P1 = Ambient Probe Calibration. Offsets temperature in degrees to
adjust the ambient probe.
H5 = Access Code to Parameters. Factory-set to 0.
H6 = Selection of Input Probe Type: PTC or NTC.
t0 = Temperature Display Limit. Maximum temperature shown on the
display, although the real temperature can be greater.
OPERATION IN CASE OF ERROR
If the probe or thermostat memory should fail, the chiller or heater will
turn off.

Error Messages

In normal operation, the probe temperature will be shown. In case of
alarm press the "SET" and the "DOWN" ▼ arrow buttons at the same
time to quit the alarm. An error messages will be shown:
•
•
•
Er – Memory error
--
Shorted –circuited probe error
oo- Open probe
