It is NOT POSSIBLE to control the actual temperature of the room/zone during this mode. However, changing the setpoint
temperature in LED is still possible. This is designed primarily for use with Timer On operation (master Wall Control). This
will allow the user to change the setpoint temperature (even when Zone Control is Off) to bring up the desired temperature
when the unit is activated via Timer On function.
