Hi all, i keep getting "hard lockout" on my brand new R7284, every time "CAD CELL" 1045ohm. Burner tech has checked oil pump pressure and for any leakage, doesn't see anything wrong, that's when i bought another R7284. its a WeilMclean with a Becket burner. it can run for several hours but never gets through the night. is the default setup ok or do i need to make some changes? i tried 2 minutes on the "Burner Off Delay", was set at 0, still locking out. the description in the manual is not great, i'm wondering if the boiler tries to restart within a couple seconds after shutting off and there's still a small fire it locksout so i think if a delay the start and if there is a small flame it might go out during the time delay? it is set for "boiler". i read in other comments the CAD CELL is more around 500-600 ohm? my last 10 cycle and Baseline are both about 1050 ohm. The tech adjusted the air intake as the cad cell previously had 1600+ ohm and said that over 1600 would cause it to lockout. he's not sure what to do that's when i bought another R7284. thanks for any help.:wall::wall::wall: Becket [COLOR=#0000cd]Separated from...[/COLOR] [url]http://www.doityourself.com/forum/gas-oil-home-heating-furnaces/518477-honeywell-r7284u-oil-primary-hardlock-out-issues.html[/url]

Hello, Long time lurker you guys have some great info. So at my house in Passaic NJ I have a Untica SVB4 Boiler. It worked great up until the nightmare deep freeze a few weeks ago. During the night a pipe froze. Popped a joint between two PEX pipes. I fixed that, ran a space heater in the crawlspace where the pipe froze. Boiler started working. I was happy. Then I noticed that it was taking forever to get the temperature back up. After long hours spent sitting along with my boiler, I have figured that the circulator pump seems to shut off midway through the warming cycle. Here's what happens: Pre-purge or whatever, the blower spins up Boiler fires (jumped thermostat wires) Feeder pipes get nice and hot, return pipes warm up. Boiler teperature stays flat at 155. Stay flat for like 4 or 5 minutes. Then the tempertature starts to spike. 156. 157. 158. 30 seconds later the boiler goes over max temp setpoint and cuts the gas. Has a brief Post-Purge phase Then it just sits there until the BT drops back under the low setpoint. It does not continue to circulate, though as I mentioned I jumped the thermostat wires. All of the baseboards - every single one - gets warm, but not hot like they did before the deep freeze. So it's pumping, but only for those few minutes. The system is 1 zone, but that 1 zone splits off to heat upstairs and downstairs. As I said, used to be the house was nice and toasty. Now I can barely walk around downstairs. Specs - As I said, this is a Utica Boiler SVB4. Honeywell Boiler Control had a long number printed on the lable - 50045578-006 Taco Circulator Pump had the number 007-F5 printed on it. This is one of those systems that pulls at the return instead of pushing at the feed. Wanted to mentioned I have bled the air out of it. Can anyone help me demystify?! :wall: Thanks
