6.16.7 Thermostat Schedule Status 1

Justification: The Thermostat Schedule Status 1 defines a “Start hour” byte that allows a schedule based on the real time in local time. We are developing a low-energy climate device that has no real time clock available. We therefore propose an additional definition of relative time within the same byte. This allows devices without a real time clock to specify a schedule relative to the current time, e.g. to perform an action in 2 hours.
