SETTINGS
Temperature Control Range Setting (TS1, DS1)
When the controller is working normally, the
PV
window displays current measured temperature,
while the
SV
window displays set temperature.
When
PV
(measured temperature) ≤
TS1
(set
temperature)
-DS1
(temperature differential value),
system will enter heating status, the
Heater
Indicator Lamp
will turn on, and heating relay
will start working; when
PV
≥
TS1
, the
Heater
Indicator Lamp
will turn off, and heating relay
will stop working.
For example, if
TS1
= 78.5°F,
DS1
= 0.5°F, when
measured temperature is lower than or equal to
78.0°F
(TS1-DS1)
, heater turns on; when the
temperature reaches 78.5°F, heater turns off.
Temperature Calibration (CA)
When there is deviation between measured
temperature and actual temperature, use
temperature calibration function to align the
measured temperature and actual temperature.
The corrected temperature is equal to temperature
before calibration plus corrected value (corrected
value could be positive value, zero, or negative value).
Display in Fahrenheit or Celsius unit (CF)
Temperature can be set to display in Fahrenheit or
Celsius according to preference. Default setting is to
display in Celsius. To display in Fahrenheit, set
CF
value to F.
Attention:
when
CF
value is changed, all other
settings will be reset to factory settings.
ERROR DESCRIPTION
Sensor fault alarm
If the controller detects a fault in the temperature
sensor, either due to a short circuit or open loop,
the controller will initiate sensor fault mode, and
cancel all the actions. An alarm will sound, and LED
will display “ER”. Buzzer alarm can be dismissed by
pressing any key. After fault is solved, the system will
return to normal operation.
Over-temperature alarm
If the measured temperature exceeds the set point
(TS) by more than 3°F, the controller will initiate
over-temperature alarm mode, and cancel all actions.
An alarm will sound and LED will display “HL”.
Buzzer alarm can be dismissed by pressing any key.
When the measured temperature returns to within
3°F of the set point, the system will resume normal
operation.
