The Sauer/Danfoss fan controller turns the fan on medium when the a/c is turned on to keep the high side pressure down, remove heat and turn the gas to liquid.
With the Source fan, do people just wait until the motor comes up to temperature before switching on the a/c?
We've bad had the SE Wax Valve, installed by SE, for about 7-8K miles now. Very pleased with the results, zero change in the reported temperature ranges I'm used to seeing. But, with the variable fan, vs Low/Medium/High of the OEM system - I'm diverting more HP to the wheels, then to the fan.
I have not changed my driving habits, as far as AC usage.
Sure not knocking the reasoning and sophistication of the OEM controller. I will however, knock the stability and quality of the unit. Not just on CC, as other coach manufactures use the same controller.
After reading of some owners of CC, and other coaches, being on number 3 or 4 controller. I elected to go with the SE Wax Valve. It is KISS.
And by the way, I've traveled in temperatures in the low 100's, including smaller mountain ranges driving, and our operating temperatures have remained between 185-195. (Final Change coolant, which after flushing and adding now three years ago, dropped temps from reported 195-205 ranges. Could have been some improvement just from flushing. But other Final Charge users have reported likewise drops in operating temperatures.) I only mention the Final Charge, and temps, in this thread - as the Source Engineering Wax Valve has handled our cooling needs well. Did not increase operating temperatures in anyways.
And the SE gang did a good job on my install. Clean, and they were very nice in taking the time to explain what, why and how they were doing things...
Best to all,
