System type 1, 2:
1 heating circuit without a mixing valve, with
DHW heating
System type 3, 6, 8:
1 heating circuit with mixing valve,
without DHW heating
System type 3, 6, 8:
1 heating circuit with mixing valve,
with DHW heating
System type 4, 5, 7:
1 heating circuit without mixing valve and 1
heating circuit with mixing valve,
without DHW heating
System type 4, 5, 7:
1 heating circuit without mixing valve; 1 htg.
circuit with mixing valve, with DHW heating
Maximum limit of the boiler
water temperature within the ranges defaulted
by the boiler coding card
Air bleed program enabled
Fill program enabled
LON participant number, adjustable from 1 to
99:
1 - 4 = Boiler
5 = Cascade
10 - ... = Vitotronic 200-H, HK1S/HK1M
99 = Vitocom
Note:
Allocate each number only once.
Without DHW priority to heating circuit pump
Without DHW priority applicable to heating
circuit pump and mixing valve
DHW priority only applicable to mixing valve
Reduced priority applied to mixing valve (the
heating circuit receives a reduced amount of
energy)
