Remarks:
1, such as: BWDK-Q201F dry-type transformer thermostat, BWDK on behalf of the thermostat national standard model, Q on behalf of inlaid iron shell thermostat, F is the code name of the communication function;
2, E, F, G, I, C are function codes, function codes can be combined, the following examples:
Thermostat model: BWDK-Q201FG, description is inlaid iron shell thermostat, its function includes: conventional function, communication function (F), and add all the way to the machine room environment temperature measurement and control function (G).
If there are already 2 functions such as E and F, and then add G and I functions, only one of them can be selected as an added function, and the maximum number of function codes that exist at the same time is 3. Examples of thermostat model numbers: 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 optic temperature measurement, etc., can contact us.
