Initial Start-up Setting
When setting up DTK for the first time, press key for more than 3 seconds till the screen display and select according to
your temperature sensor type. Please be aware that incorrect selection of a model would cause PV temperature display error. (Refer to
the chart below)
When setting up the temperature sensor type by using RS-485, write your value (range 0~14) into register 1004H.

Display Unit Setting
Use following parameter to change the PV and SV display unit, select decimal point and switch between Ԩ/Ԭ.
In Operation Mode
parameter : SP = 1 displays decimal place (ex: 25.5 degree); SP = 0 displays integral number (ex: 25
degree).
In Initial Setting Mode
parameter : Select temperature display unit Ԩ/Ԭ. (Ԭ=Ԩ* 9 / 5 + 32)
