Change
43 float C = dht.readTemperature(); // read temperature as Celsius (default)
44 float F = dht.readTemperature(true); // read temperature as Fahrenheit (if true)
too:
43 float C = dht.readTemperature(true); // read temperature as Celsius (default)
44 float F = dht.readTemperature(); // read temperature as Fahrenheit (if true)

and change
float DP = (DewPoint * 9 / 5) + 32; // converts dewPoint calculation to fahrenheit
too:
float DP = (DewPoint * C); // converts dewPoint calculation to Celsius

this should do it for you
hope this helps.

Thanks
yeah a PT100 wouldn't be to hard to use in the system, you'd have to set up the analog math and how to set up a 3 wire PT100 but it can be done I'm sure. just some research on project hub ha-ha. Then you'd have to set up 4 new menu screens for calibration and limit alarm settings but very doable.
Yes the system is still running as of a month ago when i checked in with them last (I don't work there anymore), they said they haven't had to touch them for the last few years, they just runs.
