Parameter
Sub-node
Procedure
Step 1 Run the emu add command to add a TCU. By default, the sub-node ID is 7.
NOTE
Step 2 Run the interface emu command to enter the TCU mode.
Step 3 Run the tcu heat temperature command to set the heating start temperature and the heating
stop temperature of the heat exchanger.
l When the current temperature is lower than the heating start temperature, the heater starts
heating. The default value of the heating start temperature is 5 °C.
l When the temperature after heating reaches the heating stop temperature, the heater
automatically stops heating. The default value of the heating stop temperature is 25 °C.
l When setting the heating start/stop temperature for the heat exchanger, ensure that the heating
start temperature is lower than the heating stop temperature.
Step 4 Run the tcu temperature command to set the high-temperature alarm threshold and the low-
temperature alarm threshold of the heat exchanger.
l When the current temperature of the heat exchanger is higher than the high-temperature
threshold, the excessively high temperature alarm is reported. The default value of the high-
temperature threshold is 68 °C.
l When the current temperature of the heat exchanger is lower than the low-temperature
threshold, the excessively low temperature alarm is reported. The default value of the low-
temperature threshold is -20°C.
Step 5 Run the save command to save the data.

lists the default configuration of the TCU.
Default Value
7
The TCU communicates with the MA5600T/MA5603T/MA5608T in the master node and sub-node mode.
the DIP switches of the sub-nodes for the TCU not need to be set on site.
In the TCU mode, run the display tcu system parameter command to query the parameter
configuration of the heat exchanger and ensure that the configuration is the same as the
data plan.
In the TCU mode, run the display tcu environment info command to query the running
status of the heat exchanger and ensure that it is the same as the data plan.
In the TCU mode, run the display tcu alarm command to query the alarm information
reported by the TCU. The status of all the heat exchanger alarms is normal.
