Vivax Cool: current temperature is scaled by 2.

108 is apparently a "quiet" switch.

Based on Thermor Nagano, PR #964
Confirmed in the original report #773 for Vivax Cool, 108 is an unknown bool, so
likely the same quiet function, and dp 3 was logged with a value of 49, which
is more likely a doubled temperature than unscaled.
