TABLE 11.4: OPERATING MODE PARAMETERS
Meaning
Current boiler water temperature measured by the control's sensor.
Current target temperature (always the same as the high limit setting.)
Boiler will stop firing if boiler water temperature exceeds this value (Circulator/s
will continue to operate)
If high limit setting is reached, boiler water temperature will need to drop by this
amount before boiler will again fire during the same call for heat.
Shown as either ON or OFF. Indicates whether there is a call for heat.
Shown as either ON or OFF. Indicates whether there is a call for domestic
hot water (DHW). Note that if the dh zone on the S9361A is used as a second
heating zone (see Table 11.5), this parameter will be shown as OFF and tt will be
shown as ON when this zone calls for heat.
Flame rectification signal (uA)
Total amount of time gas valve has been open (burner firing) since control was
new (hours, starting from 1).
Total number of burner cycles on the control
Present only if the control has detected a problem. See Table
