Attic vent fan on thermostat
« on: July 05, 2016, 10:37:23 am »
Anyone have a solution to replacing these types of fan thermostats?  I have two of these that I cannot reach without climbing over a blower or crawling through a crawl space.  The sensor must remain in this location due to needing to be at the highest & hottest place in the house roof, but I would like to bring the control to both thermostats to a more convenient location and of course ideally into my Vera Plus.

I could probably turn the thermostat down to make it pass current at the lowest temp and then use a regular Zwave switch that is triggered using an Ecobee remote sensor in place of the standard wall switch on the circuit, but then I would still have to get up there to replace the battery in the sensor from time to time so will have to figure out an AC powered temp sensor.

The aeotec multisensors can be USB powered. I wouldn't want a generic transformer in my attic but you could mount a USB/110 outlet in a covered box and drill a small hole for the USB cable.

I have two attic fans and use RANCO ETC-111000 Digital Cold Temperature Control to control both of them
