Boiler was working this morning and for the past 8 years. Now the controller reads Standby. No other activity.
Primary Controller
Honeywell R7284 P1080 on STANDBY
Software Version 19
TT On, Limit Open, Cad Cell 999999 Ohms
Cad Cell
Last Cycle 426 Ohms
Last 10 Cycles 398 ohms
Baseline 165 ohms
Ignition time last 10 cycles 00:01
0 Lockouts since Baseline
Beckett AFG Series Oil Burner
Low Water Cut-Off
Hydrolevel CycleGard CG450-1560
Steam heat.
Hot water on demand.
Neither steam nor HW demands are causing the boiler to ignite.
I replaced the Controller with same as existing.
Ohm-Checked transformer and it is working properly.
There is continuity between the red Burner wire in the LWCO and the red Limit wire in the Controller.
In order to get some heat in the house I change the settings of the controller to TT Open and Limit Closed, put a jumper on the TT terminals of the Controller, and connected the red Burner wire in the LWCO with the orange wire on the P2 terminal.
Burner ignited, ran 10 mins, shut down for a couple of minutes and then ignited again keeping this cycle going for 45 mins. Then the Pressure Relief Valve opened. Whoa !!! That’s an experience. Pressure was only 2.5 psi. Hence it was also replaced today.
I just replaced the LWCO with same. The existing unit’s probe was leaking. And wired it as originally wired. So, now that we have lots of brand new components it should fire right up. NOPE !!!
Any ideas?
