Too warm:
If a module's temperature exceeds a theshold value, the module sends a warning to the
head module. If the temperature drops back below the threshold value, the module
sends an all-clear.
}
Too hot:
If a module's temperature exceeds a further theshold value, the module sends an error
message to the head module and switches off the relay outputs.
}
After the "too hot" message has been received, if the temperature drops back below the
"too warm" theshold value, the relay contacts will close if the head module has set the
status of the outputs to "1".
