5. Parameter Settings

To change the tar get temper ature or humidity , press SET key

momentarily. The controller will show tSP (temperature set point),

press SET again will show HSP (humidity set point). Use Up or Down

key to change the tSP or HSP.

To change the other parmameters, press SET key for 5 seconds, the

RH window will show tE or Hu (depending on which menu was set

last time), press SET key to enter the set menu for temper ature

control or humidity control. Or press Down (or Up) key to change the

RH (or Hu) window to Hu (or RH). Then press SET key to enter the

set menu for humidity (or temperature) control.

To s et up the while in the parameter setup mode, use Up or D own

key to modify the parameter value. Then press SET key to confirm

the change. The instrument will automatically exit if no key is pressed

for 10 seconds. Please see the Table 1 for the parameters.

Note 1.

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

temperature (or humidity) reaches the set point; will be on again

when the temperature (or humidity) drops down to tSP-tdF (or HSP-

HdF).

For cooling (or dehumidi fying ), the output w ill be off when the

temperature (or humidity) reahes the set point; will be on again when

the temperature (or humidity) rises to tSP+tdF (or HSP+HdF).

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.

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 37 ºF when the

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

controller display 32 ºF.

Note 3.

The low limit alarm will be always lower than the high limit

alarm. When the measured temperature (humidity) is higher than tAH

(HAH), the temperature (humidity) high limit alarm w ill be on; when

the measured temperature (humidity) is lower than tAL (HAL), the

temperature (humidity) 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, pr ess the

Down key momentarily. When the alarm is muted, the alarm indicator

(see F igure 1, the small dot on the last di git ) w ill be on. 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 resume the alarm,

press the Up key, the alarm indicator will be off.

To disable the alarm, set High Limit Alarm= Low Limit Alarm.

Note 4.

When T he controller is used for cooling (or dehumidifying

control) and load is a compressor, it should not turn on the

compressor when it is at high pressure (just after turned off).

Otherwise, It may shorten the life of 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. contacts

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 5.

The TSF (HSF) can be set to ON or OFF. When it is set to

ON, the output will always be on when the sensor fails; when it is set

to OFF, the output will always be off when the sensor fails.

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 TSF to OFF for

safety purpose .
