contact remains open (after reaching cutout) before closing again. The

delay overrides any Load Demand and does not allow the NO contacts

to close until the set time-delay value has elapsed. It gives time to

release the refrigerant pressure through evaporator. It is typically set to

4 ~ 6 minutes.

Note 4. The SFA defines how the output would be if the sensor fails. It

can be set to 0-0, 0-1 or 1-0. Please refer to table 2 for details.

Table 2. Output of the controller when sensor fails:

SFA

Controller output when sensor fails

0-0

1-0

0-1

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

want to set the SFA 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.

Note 5. The offset is used to set an input offset to compensate the

error produced by the sensor or input signal itself.

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

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

controller display 32ºF.

Note 6. C-F determines the temperature unit. It can be set to C

(Celsius, ˚C) or F (Fahrenheit, ˚F).

Note 7. LGC Control Logic (advanced feature). This parameter is used

to change the current control logic mode. Three modes are available:

• NOR -- normal control logic (default)

• R-C -- reverse logic, output send to Cooling socket (left)

• R-H -- reverse logic, output send to Heating socket (right)

If set to default mode (NOR), when this controller is calling for heat, the

heating output socket on the right will be triggered. When this controller

is calling for cool, the cooling output socket on the left will be triggered.

If set to reverse modes (R-C/R-H), when this controller is calling for

heat or cool, the output is disabled. In other conditions, the output will

be triggered. You can assign this output to cooling socket (R-C), or

heating socket (R-H). For details, see flow chart below.

Explanation:

1. The plot on the top shows how the room temperature changes as

time goes by. The diagram on the bottom shows the status of the

output relay as temperature move across each set point.
