Fantastic Fan Fantastic Thermostat

[Brownghost]

My HT38FL has three exhaust fans, one in the living room, one in the bathroom and one in the bedroom. Each one of the fans is controlled by an individualthermostat. None of my fans work as designed. The LR fan doesn't work at all unless in manual mode, the other two fans will open the vent but the fan will not turn on. I am suspecting the cheap thermostats are the problem.

I would like to swap out the cheap thermostats with controllers fromFantastic Vent. I had one of these in a previous RV and it worked beautifully. You could set the operation by temperature which would modulate the fan speedor by percentage of fan speed. An LED readout gave you the settings and temps.



Has anyone had problems with their fan thermostats and what have they done to rectify the problem? Any thoughts on if the swap could be done?



Thanks in advance,
