My AC is a pair of aeroscreens so possibly showing my ignorance, but couldn't you put a manual tap in the feed to the heater matrix? ... work of moments to isolate the heater on hot days or vice-versa ??🙂

It's not a single feed and it is part of the circulation system, you can't just shut it off easily. It looks like it would need 3 taps and a bypass pipe. Probably be easier
to Aberdeen where I wouldn't need it
