Cooling Fan, Temperature Control Unit Support Cabinet, Rack

Digital Temperature Unit 
I Size : 1U 19inch
II Technical Parameters:
Input: 150V~265VAC 47~63Hz Output: 150V~265VAC 47~63Hz 13A
III Instructions

3.1 Proper working display :
Real -time clock, the current temperature, fan state are showed on the display;
3.2 Temperature setting status display:
1. Press the "+" key to display the setting temperature of upper limit;  press "-" to display the setting temperature of lower limit; 
2.Pressing the "Temp" more than 3 seconds to enter modify mode of the temperature parameters, display "Set Tem" at the same time,then press "Temp" in turn display F1~F6 parameter value,and press the"+""-"key can modify the current F1~F6 parameter values.
3.Once setting up completed, press the "Temp" button more than 3 seconds, return to the normal display status.
Function Menu:

ITEMS	FUNCTION	SETTING RANGE	UNIT	Default
F1	Upper limit	F2~60	ºC	25
F2	Lower limit	-40~F1	ºC	15
F3	Temperature calibration	-5~5	ºC	0.0
F4	Output protection time	0~9	Min	3
F5	Exceeding temperature offset	0~50	ºC	5.0
F6	Exceeding temperature alarm delay time	0~99	Min	5

F1:Temperature upper limit:when the actual temperature is higher than the setting temperature alue,the fan start automatically.
F2:Temperature lower limit:when the actual temperature is lower than the temperature,the fan stop.
F3:Temperature calibration :When the measuring temperature value and the actual real temperature deviate,it will correct the temperature with this calibration value,in order to achieve the measurement accuracy.
F4:Output protection time:When the fan start-up, it has to run continuously for this time value to stop.
F5:Exceeding temperature offset:The default actual temperature value beyond the upper limit or below the lower limit temperature value.
F6:Exceeding temperature alarm delay time:When the actual temperature beyond the temperature value "F1+F5",or below the temperature value "F2-F5",the delay buzzer alarm.
4.Clock setting:
Pressing "Time" button more than 3 secondsto enterthe state of the clock Settings, then press the "Temp" key switch in turn to set the correct time "hour", "minute", "seconds" state, press "+", "-" button to set the current clock.
IV  Alarm instructions:
When actualtemperature is higher than set temperature F1 + F5 Value or lower than set F2 -F5.value, the alarm indicator start flashing, after the setting time "F6", the buzzer starts alerting until the temperature is adjusted to the normal temperature.
