I have a 20 minute push button in my washroom that puts the HRV on high speed for 20 minutes and would like to be able to automate this. How do these work. There are 3 wires connecting the switch to the HRV. Are they sending a signal to the HRV or simply closing a contact in the switch?

I believe HRVs usually have a proprietary communication method with their controllers. There was a CCT thread where someone managed to figure out how his worked. Seemed a little above my pay grade.Originally posted by rpradeThere is no rhyme or reason to the anarchy a defective Z-Wave device can cause
