5. Parameter Settings
To change the target temperature 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 temperature
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 Down
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.

Table 1. Parameters Description
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 will 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 will 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, press the
Down key momentarily. When the alarm is muted, the alarm indicator
(see F igure 1, the small dot on the last di git ) will 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 .
