Here in Sedona AZ and it got down to 29 last night. My Webasto seems to have a problem wanting to start the second time. If I set the controls to a temp of 65 and turn it on it starts and runs then the burner turns off and as the coolant get cool the burner will not start again unless I shut the system down and start over. Any ideas out there? I have the webasto set up with four area to call for heat (water bay, bedroom, bathroom, and kitchen/living room). I have SMX controllers in all areas except the water bay.
