Conditions for operation

Maintaining the specified operating conditions will enable
the boiler to provide a high level of reliability and long serv-
ice life. Some details relate only to operation with Buderus
Logamatic control panels.
Caution: Risk of system damage if operating
conditions are not maintained.
Irreversible damage to individual compo-
nents of the boiler as a whole or the heating
system may occur.

Tab. 4 General operating conditions
1) A heating circuit with a mixing valve improves controllability and is specifically recommended for systems with several heating zones.
2) If heating zones or a boiler circuit actuator cannot be regulated via the control device (for example pump logic), an operating temperature of
122 °F must be reached within 10 min of switching the burner ON by restricting the water volume flow.
3) Boiler water temperature control setting: when the boiler is in ON mode, the minimum boiler water temperature in the boiler must be reached
within 10 minutes, e.g. by flow rate limitation, and maintained as the minimum temperature.
