5. Parameter Settings

To change the target temperature, 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.

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. Please see the Table 1 for the parameters.

Note 1.

For cooling (or heating), the output will be off when the

temperature is blow (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 -58~248 ºF or

-50~125 ºC. 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=67.0 ºF, HSP=62 ºF, HSP can be set to any

value between -58 and 67.0. For CSP, it can be set to any value

between -58 and 248. If you set it to 55.0, the HSP will be set to 55.0

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.

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=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 -58~248 ºF or

-50~125 ºC. 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=95.0 ºF, AL=32 ºF, AL can be set to any

prevent the rapid cycling of the compressor. It establishes the

For example, when the unit controls a refrigerator for food, you may

want to set the TSF to ON if the sensor fails to keep the food cold.

When it controls a heater, you may want to set the output to OFF for

safety purpose .

For example, for temperature, if the unit displays 37 ºF when the

actual temperature is 32 ºF, setting parameter toF= - 5 will make the

controller display 32 ºF.

6. How to install the sensor to the unit.

The connector of sensor contains a slot for correct pin connection. It

also has a spring lock to prevent disconnections from accidental

pulling on the cable. To install the to the unit, please align the slot of
