For interior cement plaster, I think that it's probably best to keep the interior 
as cool as possible without letting it freeze.

Why ?

If the interior is kept hot, I bet that the heat would try and find its way to 
the cooler outdoors via the shortest route it can find ... and one of those 
routes would likely be through the straw.  The downside is that the heat could 
likely be carrying moisture with it and that moisture would likely condense within
the bale wall .

Not only would that be potentially bad for the straw, it'd also be bad for the plaster
because that moisture would no longer be available to the cement to enable it to
fully hydrate.

On the other hand, with cooler temps, it would seems that more of the moisture 
would tend  to stay in the plaster making itself available to the hydrating cement.
Longer moist curing results in better concrete and cement plaster.
