II: Technical Parameters
1, Power: 230VAC
2, temperature probe: NTC, one, two meters long (regardless of sign)
3, the temperature display range: -45 ~ 120 °C (-49 ~ 248 ° F) Accuracy: ± 1 °C (± 2 ° F)
Resolution: 0.1 °C (-19.9-99.9 °C)
4, the control temperature range: -45 ~ 120 °C (-49 ~ 248 ° F) Default value: 0 °C (32 ° F)
5, the working environment temperature: -10 ~ 60 °C (14 ~ 140 ° F): Relative Humidity: 20% ~ 90% (non-condensing)
6, contact capacity:
· Control Output: normally open 16A/250VAC
Third, the panel operation
1, temperature control (shutdown temperature) adjustment: press the set button flashes to control the temperature, press or key to change the value and memories. Hold down the key and button and hold for more than 2 seconds to quickly increase or decrease the value. Press the set button to exit adjust status display cabinet temperature; If you do not press any key, the display cabinet temperature recovery after six seconds. (Control of temperature adjustment range: Parameter E 1 ~ parameter E 2)
2, cooling indicator: refrigeration process, refrigeration lights; constant temperature refrigeration lights off; delay the process, refrigeration lights flashing.
3, the heating indicator: the heating process, heating lights; constant temperature heating lamp; delay the process, heat lamp blinks.
4, parameter settings:
· Press the set button for six seconds after entering the parameter setting, while flashes E 1;
· Press the key to change the parameter set selection, order display E 2, E 3, E 4, E 5, C1, C2, E 1;
· Press the or key to display and modify the value of this parameter, the stored data;
Not press any key within six seconds to return to normal operation.
5 , restore the factory settings : hold down down key for one second , and then hold down the up key six seconds , the display flashes. At this point all parameters restored to factory default , six seconds after the return to normal operation.
6 , parameter lock : Press the down key for six seconds , flashing "OFF" means locked, "ON" indicates unlocked. Lock
After setting the parameters , the parameters can only view can not be changed . Controlled temperature regulation is still valid. ( Factory default "O N")
Fourth, the functional description
1, the cooling control:
· Temperature control mode ( parameter C2) is set to 0 , the compressor after a delay , when the cabinet temperature is greater than ( control temperature + temperature difference ) ,
Compressor starts , cabinet temperature is less than the control temperature, the compressor stops.
· To protect the compressor , the compressor stops every time must exceed the delay time (E4 parameters ) can be re- started.
2 , the heating control
· Temperature control ( parameter C2) is set to 1 , the delay through the heater , when the cabinet temperature is lower than ( the control temperature - temperature difference ) , the heater starts heating cabinet temperature greater than the control temperature, the heater stops heating .
3 , non- normal operating mode :
· Cabinet temperature probe short circuit or high temperature gauge ( greater than 120 °C / 248 ° F) display "HH"; cabinet temperature probe open or low overrun ( less than -45 °C / -41 ° F) to display "LL". Warning lights flashing.
V. Installation Precautions
1 , in order to prevent high-frequency interference , the probe line in conjunction with power lines or bundle of parallel control lines to separate wiring .
2 , such as the installation need to extend the probe lines up to 100 meters , is not subject to re- examination.
3, the thermostat can not be installed where there is dripping .
