6. Parameter Settings
To change the target temperature (set points), press SET key
momentarily. The controller will show CSP (Cooling set point), press
SET again will show HSP (heating set point). When the controller
shows CSP or HSP, use Up or Down key to change the value. Then
press SET key to confirm the change. See figure 2 for details
To change the system parameters, press SET key for 5 seconds, the
controller will enter the parameter set up mode. The first parameter AH
will show on the display. Use Up or Down key to modify the parameter
value. Then press SET key to confirm the change. The display will
show the parameter again. Press the SET key to show the next
parameter. The instrument will automatically exit if no key is pressed
for 10 seconds. See figure 3 & table 1 for details.
Note 1.
For cooling (or heating), the output will be off when the
temperature is below (or over) the set point; will be on again when the
temperature rises up (or drops down) to CSP + CdF (or HSP - HdF).
The maximum value of the HSP can be set is the current value of CSP.
But CSP can be set to the value between -58 ~ 248ºF or -50 ~ 125ºC.
When the CSP is set to a value lower than current HSP, the HSP will
be adjusted to the CSP value automatically.
For example, when CSP = 67.0ºF, HSP = 62ºF, HSP can be set to any
value between -58ºF and 67.0ºF. For CSP, it can still be set to any
value between -58ºF and 248ºF. If you set it to 55.0, the HSP will be
adjusted to 55.0ºF automatically.
Small differential gives tight control; large differential reduces the
frequency of cycle on and off. It will extend the life of relay and
compressor.

Note 2.
When the measured temperature is higher than AH, the high
limit alarm will be on; when the measured temperature is lower than AL,
the low limit alarm will be on.
When alarm is on, the display will be flashing between the measured
value and alarm type. To mute the alarm when it is on, press the Down
key momentarily. If the measured value gets out of the alarm zone then
gets back to the alarm zone again, the alarm will be on again. To
disable the alarm, set AH the same value as AL (AH = AL).
The maximum value of the AL can be set is the current value of AH.
But AH can be set to the value between -58 ~ 248ºF or -50 ~ 125ºC.
When AH is set to a value lower than current AL, the AL will be
adjusted to the AH value automatically.
For example, when AH = 95.0ºF, AL = 32ºF, AL can be set to any value
between -58ºF and 95.0ºF. For AH, it can be set to any value between
-58ºF and 248ºF. If you set it to 25.0ºF, the AL will be adjusted to
25.0ºF automatically.
Note 3.
The Cooling Anti-short is the delay time to turn the cooling load
on.
W
hen the controller is used for cooling and load is a compressor, it
should not turn on the compressor when it is at high pressure (just right
after it turned off). Otherwise, it may shorten the life of the compressor.
The Anti-short cycle delay function can be used to prevent the rapid
cycling of the compressor. It establishes the minimum time that the NO
