Good Morning
41° and sunny, high of 70 under continued sunshine.
Yesterday was spent on a combination of chores. Started off welding up some aluminum parts for a handicap ramp for neighbor to load wheel chairs onto hay wagons at their “agritainment farm”. They have a winery, Christmas trees and pumpkins.
There 8 of these, TIG welded using the aforementioned Primeweld welder.
Had success getting the engine running on the RC plane after sitting for 25 years or more.
Here it is behind the KubVan for scale.
The geothermal installation is almost complete, there is an issue with the modulating water valve that adjusts the flow of water though the heat exchanger. It takes well water into it and returns it to the pond, the valve adjusts the flow to maintain a programmed delta T. We usually set it at 11°.
The valve isn’t working. It uses 24vac for power and a 0-10v control signal to modulate it.
I guess I’ll start with verifying the wiring, jumper and DIP switch settings, then check voltages. My guess is it’s an installation error, not hardware failure.
No music tonight, we are loading gear into either the trailer or KubVan as we are playing both tomorrow and Sunday at a fall festival in Buckingham.
Gonna try and squeeze some RC time in this morning, then look at the heat pump, clean up the mess I made in the shop yesterday, and take a swing at whatever else gets pitched my way.
