A possible answer for your situation is to use Diafine for developing film. It is insensitive to temperatures between 70 and 85 degrees, as well as time and agitation variations. It is pretty fool proof.(posted 8679 days ago)For printing, the temperatures are not real important unless you have extreme temperature swings say over 80 degrees. If you know that the temperature only varies between 70 and 80 degrees, I wouldn't worry about print solution temperatures.
