need low voltage basic timer for ERV
GW
Member Posts: 4,832
we did a geothermal install (removed conventional AHU/HP), and the existing ERV was not in operation when we arrived. So now we are up and running, but in order to make any sense out of the erv we need some basic timer.
I spent a few minutes searching but can't locate one that seems to fit the bill, anyone have any good choices?
We are simply going to mount the thing in the basement near our equipment, the erv is several feet away.
Thanks, Gary

Can you download the installation instructions from the manufacturer's website? My Fantech HRV provides DEHUM terminals which, when jumped, turn on the unit, and INTERLOCK terminals which can be used to kick on the air handler fan. Actually these terminals were not well documented and a call to Tech Support was very helpful in setting it up.
I use motion sensor fan switches in my bathrooms to turn on the lights and run the HRV; it continues to run for 10 minutes after lights go out. Fantech also makes a proprietary control (two-wire serial interface) for use with the unit, and you can set it to cycle on/off for various speeds/intervals.
You should be able to wire up a constant on-off cycle using one of these (and possibly a relay):

but you would need to know what your ERV is expecting.

Thanks all, I tried the old fashioned method of calling the local vendor, got transferred to the smart guy at the next branch. He ordered me a soler palau FT247.
I appreciate the replies.0
