1. The main module defines the frame with the MCbus communication buffer. D component definition is
shown in the table below
Table 3-5 Settings indicate special meaning of communication D element
2. MTC thermostat return the frame with the MCbus communication buffer. Take MTC#1 region as an
example: when D7532 and D7563 become 5, data can be read from MTC, up to 30 D elements can be
read at a time, as shown in the following table.
