Supply Temperature Control - Buderus G315 Assembly, Maintenance And Operating Instruction

14 Supply Temperature Control

Supply temperature control
An "Open-On-Rise" aquastat is required to interrupt water circulation through the boiler to prevent
the supply temperature from dropping below 122°F during burner operation. The aquastat is to
temporarily stop operation of the main system pump (or individual boiler pumps in case of a
multiple boiler installation).
Refer to Figure 45 for a typical control schematic for a single boiler with supply temperature control.
Control components can be furnished by Buderus Hydronic Systems, Inc.; relay, burner and circulator
operating controls can not be provided.
