The low temp alarm went off at 1:30 this morning. The heater is going into lockout. Adjusted the sensor again and monitored it. Lockout happened again. I set the fan up and blew the heated porch air into the greenhouse for the night. Overnight low was 28.
Called Dornback again. I have to send back the controller to get a new one. Went to Trader Joes and Krogers for Tuesday groceries. On the trip I began to think about the sensor. If it opens up when heated the controller will lockout the heater. I think that's what's going on, we're getting intermittent at high temperatures. I went to Home Depot and picked up a Honeywell Universal ignitor. Will try that tonight to see how it performs. The great news is that it works at all!!! It's shaped differently. Managed to shovel up the dirt for the next walkaway. Removed 7 wheelbarrows worth of dirt. I'm now ready for the walkway framing. Dinner was lobster pasta. Afterwards I listened to Kovaschina live from the Met.
