These two warning are likely not related.
The first warning is suggesting that the difference between the zone temperature and supply air temperature is too small which can lead to extremely high zone air flow rates. If the zone temperature is 26.7C, then a likely choice for supply air temperature would be 5C lower or 21.7C.
The second warning relates to how the simulation is warming up and converging on the initial conditions. For some reason, the successive simulation of this model does not converge on the same cooling and/or heating loads. However, the comparison between the actual and the tolerance is not that great at 0.06 vs 0.04 so you can probably disregard this specific warning.

These two warning are likely not related.
The first warning is suggesting that the difference between the zone temperature and supply air temperature is too small which can lead to extremely high zone air flow rates. If the zone temperature is 26.7C, then a likely choice for supply air temperature would be at least 5C lower or no greater than 21.7C.
The second warning relates to how the simulation is warming up and converging on the initial conditions. For some reason, the successive simulation of this model does not converge on the same cooling and/or heating loads. However, the comparison between the actual and the tolerance is not that great at 0.06 vs 0.04 so you can probably disregard this specific warning.
