Room Thermostat and Remote Control Module
The controller should load its main screen within 3 seconds. If this doesn't happen and the
Executive module's version is missing (“--” instead of numbers), that means there is a
communication problem between the modules or the
Executive module
is not working. To
solve the problem, check the green LED located on the board. When working normally, it
should blink every 0.5 seconds. If you have a case where the light blinks normally but there is
no software version being displayed, the problem might be in the connection between the two
modules. If the LED is blinking every 2.4 seconds, it means that there is no pre-installed
software on the Executive module. Use the remote monitoring and control program to upload
the software in the module. If after turning the power ON and the LED blinks once per
second, this means that there is no communication between the two modules. You have to
check the connection between them.
If by three seconds the screen does not shift to the main screen and the controller version text
turns red, it means that there is a hardware incompatibility between the modules.
If by three seconds the screen does not go to the main screen and the software version of the
Executive module turns red, it means there is a software incompatibility between the modules.
