TidePool

I'd like in please, PM sent.

I'm not an HVAC tech, but I am a retired electrician.

1st step I'd take is to use a voltmeter to check for voltage at the relay coil terminals. Since you are using DC you need to make sure you have correct polarity at the relay coil.

If you have correct voltage and polarity at the coil, and the coil does not operate, then the coil is defective. If the polarity is incorrect, reverse the wires at the coil. If the voltage is not correct, at the relay coil, then you have a problem with the control circuit.

Make sure the stat contacts are rated for DC current (most are rated for 24 VAC). When I have done projects using these types of stats I always used relays with 24VAC coils. DC current is much harder on contacts than AC current.

Good Luck

Please count me in, PM sent.

Count me in.

I use API for some of my testing, but for nitrates I prefer the SERA test.

I am using something similar. I picked up some acrylic sheets (24 X 48 X .080) at Lowe's. I put the acrylic sheets over the particle board, providing a durable and waterproof surface. The acrylic is about $20 a sheet. That adds up, but I just don't trust the particle board if it gets wet.

I'd be in for 150. I could hold it for TRENT in Eugene if we can figure out a way to get it here? Are you driving through Tidepool?

Yes, I offered to bring sand down to Eugene for Trent, he is apparently making other arrangements.

I'm wondering if this group buy is still on. If so I'd like in for 200 lbs.
