BWDK-Q201 dry transformer thermostat model selection instructions
| model | Function |
| BWDK-Q201D | Three-phase tour display/maximum display；Fan automatically/manually start and stop；Overtemperature alarm；Overtemperature trip；Fault alarm；"Black Box" function； Fan timing excitation function；Simulation test function；Digital compensation function；Cabinet door opening alarm function。 |
| BWDK-Q201E | The same as the BWDK-Q201D model，Add 4~20mA analog current output。 |
| BWDK-Q201F | The same as the BWDK-Q201D model，Added RS485/232 serial communication function。 |
| BWDK-Q201G | The same as the BWDK-Q201D model，Added ambient temperature measurement and control of the computer room all the way。 |
| BWDK-Q201I | The same as the BWDK-Q201D model，Added ambient temperature measurement and control of the computer room all the way。 |
| BWDK-Q201C | The same as the BWDK-Q201D model，Add the thermistor PTC150 or PTC130 for interlocking control。 |
Remark：
1、like：BWDK-Q201F dry transformer thermostat，BWDK represents the national standard model of thermostat，Q represents inlaid iron housing thermostat，F(xiàn) is the code name for communication function；
2、E、F、G、I、C is function code，F(xiàn)unctional codes can be combined，The following examples are given：
Thermotor model：BWDK-Q201FG，Instructed iron shell thermostat，Its functions include：General functions、Communication function (F)，And add ambient temperature measurement and control function of the computer room all the way (G)。
If you already have 2 functions such as E and F，Add G later、Only one of the I functions can be selected as an additional function，There are up to 3 functional codes that exist at the same time，Examples of thermostat models：BWDK-Q201EFG、Bwdk-q201efi。
3、If there are other special technical or functional requirements，Such as Ethernet communication、Profibus Communication、Multi-channel temperature measurement、Fiber temperature measurement, etc.，You can contact us。
