Construction on Tiny Refuge has gone from a weekend affair to a fully time occupation. I will be living in Tiny Refuge in a matter of weeks.
The electrical is completed as far as it can until the bathroom is finished, the ceiling under the loft is put in and the floors are finished. The Lunos e2 HRV (heat recovery ventilator) was hooked up and tested. It took a little doing as there was a misunderstanding about how the switches needed to be setup. The box we received with the HRV was a european one and it fit the transformer that controls the HRV units, so we installed it. Oops. The european box, that had the wires for the HRV running to it, had to be carefully excavated from the wall and a triple gang box was installed into the wall. The Lunos e2 needs two switches, one switch turns the units on and the second switch controls the speed (low or high). The switches needed a triple gang box because a double gang box doesn’t have enough space for the switches and the transformer. In the third space in the box, a blank switch was installed and a hole drilled through it for the transformer’s LED.
With the switches and the transformer in place, the tubes were cut to size, the units were put in place and hooked up and then tested. There was a slight delay as they started up, once they started they quietly purred and worked beautifully. The Lunos e2 HRV must be installed in pairs. One unit draws fresh air in as the other draws the “stale” air out, then after about a minute later, they switch. They make very little noise, even on the high setting. It was wonderful to hear them purr.
