Digital Temperature Controller With Sensor Thermostat For Incubator
Function Description:
1, Cooling control:
• When the temperature control mode (parameter C2) is set to 0,
after the compressor has been delayed, When the cabinet temperature
is greater than (control temperature + temperature difference), the
compressor starts . Cabinet temperature is less than the control
temperature, the compressor stops.|
• To protect the compressor, the time for the compressor to stop
each time must exceed the delay time (E4 parameter), then compress
can restart.
2, Heating control:
• Temperature control mode (parameter C2) is set to 1, the heater
after a delay, when the cabinet temperature is less than (control
temperature - temperature difference), the heater began to heat.
Cabinet temperature is greater than the control temperature, the
heater stops heating.
3, Alarm function:
• After the initial shutdown, when the sensor temperature
exceeds the P1 maximum alarm value, or less than P2 minimum alarm
value, and the continuous time exceeds the alarm delay time P3,
enter the alarm state.
• When the alarm indicator flashes, the alarm relay is on. Press
any key to stop flashing, but still on. When the temperature
returns to normal, the alarm relay is disconnected and the alarm
indicator goes off.
• In the high temperature alarm, when the cabinet temperature is
lower than (P1 maximum alarm value - alarm hysteresis P4), out of
the alarm.
• In the low temperature alarm, when the cabinet temperature is
higher than (P2 maximum alarm value + alarm hysteresis P4), out of
the alarm.
• Connected to the power supply after two seconds, when the library
temperature in a constant temperature state, the direct start of
the alarm without the need for the initial shutdown.
• When adjusting the alarm parameter value, the high temperature
alarm value (P1 parameter) must be greater than the low temperature
alarm value (P2 parameter) .
4, Abnormal mode of operation:
Cabinet temperature probe short circuit or high temperature limit
(greater than 120 ℃ 248 ℉) show "HH" ; Cabinet temperature probe
open or low temperature limit (less than - ℃ - ℉) show "LL". The
alarm light flashes .
Installation precautions:
1, To prevent high frequency interference, the probe line can not
be bundled with the power line or control line parallel, to
separate wiring.
2, Such as installation needs, can extend the probe line up to 100
meters, no need to re-check.
3, The thermostat can not be installed in a dripping place.
