Current target temperature (always the same as the high limit setting un-
less Crown outdoor reset card option is installed).
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 domestic
