Key (for steps B3 & B5):

A = Current cycle data being displayed (1 being the most recent cycle) B = Burner on time in minutes:seconds

C = Burner off time in minutes:seconds

D = Average water temperature over burner off-on cycle. E = Cycle start reason:

LL = burner turned on to maintain low limit.

TT= burner turned on to satisfy a thermostat call for heat. ZR = burner turned on to satisfy a ZR call for heat.

F = Cycle end reason:

CFH = the call for heat (from T-T or ZR) was satisfied

HL = the boiler water temperature reached the high operating limit.

LL= the boiler water temperature reached the low limit plus low differential.

Lockout reasons (see Lockout Troubleshooting section for more details): SENSOR ERR, SELF-CHECK, CANCEL

C.Changing the Circulator Settings

The circulator-off delay keeps the C1 output energized for the set time after a call for heat ends. This helps to increase the efficiency of the system by transferring more heat into the home instead of letting it sit in the boiler.

The circulator-on delay holds the C1 output off for the set time at the start of a call for heat. This helps the boiler to heat up more quickly and spend less time in the condensing range (if applicable).

Both circulator delays are selectable from 0 to 4 minutes and 15 seconds.
