Configuration

Function block "Boiler sequence manager" is activated by selecting a plant type in the
basic configuration. If several RMK770 controllers are used, the boiler sequence man-
ager function is always provided by the RMK770 that can acquire the main flow tem-
perature.
A plant type always requires the configuration of a main flow temperature sensor and a
main return temperature sensor. If more than 1 RMK770 is used for a boiler sequence,
these sensors may only be configured with the active "Boiler sequence manager"
function block.
For each boiler sequence, use of a main flow temperature sensor is highly recom-
mended.
