Heating and Cooling Output (M+M_HTCL_T_)

M+M_HTCL_T_
This FB outputs two manipulated values after split conversion and output conversion to setting values. It can perform
temperature control by outputting the values to both the heating and cooling operation terminal. The primary loop can be
tracked.
