Nicholas,
You can certainly do that. Most newer controllers have a “vacation” function that will provide this. Another method is to put in a bypass to the

Apologies if this has already been discussed here.
One heat diversion method I hear suggested often is recirculating through
the collectors (flatplate) at night. Are there any data, calculations or
anecdotal evidence on the effectivene
multiplied by the
temperature difference, and the loss coefficent Frul for the collector.

Nighttime cooling is possible, it works, and there's some pretty good data
being collected about it recently. The actual amount of energy that you can
radiate out depends on many factors, including ambient nighttime air
temperatures, the dew point in your area, and the emissivity of your
collector
