Write command 7
1. The main module defines the frame with the MCbus communication buffer. See tables 3-6 and 3-7 for
the definition of D components and write command 7.
Table 3-9 Settings represent communication special meaning D element

2. MTC thermostat return the frame with the MCbus communication buffer. Take MTC#1 region as an
example: when D7532 and D7563 change to 7, the write is successful and up to 30 D elements can be
written at a time. The return frame definition is shown in the following table.
