This turned into an eventful day. I finished up the controller by testing the cold temp response with ice cubes then went over to the greenhouse and hooked everything up. Went home for lunch then returned and soldered the wires for the transfer relay and tested the generator and manually threw the relay to see if it worked. It did. This relay uses a 24 VAC transformer, the others are directly hooked up to 110VAC for transfer. Put a new piece of strip tape across the back because the old one disintegrated. I did this while the generator was running it's test cycle. The generator seems hard to start - it may have old gas or may need new plugs. Next I hooked the thermostat wiring to the LOGE controller by putting a few jumpers in the box above the entry door. Ran the aux heater and Libbie and I punched holes in the unpunched distribution heat tube on the side facing the greenhouse space. The heat seems to be working OK. After a dinner of French Vegetable jambalaya with chicken, we went back out to the greenhouse to do some temperature measurements. I checked over the aux heater exhaust and we measured temperatures at various places in the greenhouse. The bench tops were mostly at 65 to 68. The outdoor temp was 42 while the telephone probe was reporting 64 and the LOGE indoor probe was reading 68.
