*1 Pin No. of temperature controller differs depending on the model. Refer to the following table.
Signal name
*2 Terminating resistor should be provided for a GOT and a temperature controller which will be a terminal.
*3 For GT27 and GT25 (except for GT2505-V), set the terminating resistor to "Enable".
For GT2505-V, set the terminating resistor to "110 Ω".
