8-11
Function: This function regulates the necessary measures when the permitted flue gas
temperature is exceeded.
Displays only flue gas temperature
No function for control; the current flue gas temperature appears on the information
display.
Heat generator locking in case of exceeding limit for the set time
If the limit value is exceeded, the heat generator is blocked for the set time and a
malfunction message is triggered.
Heat generator blockage in case of exceeding limit
If the limit value is exceeded, the burner is blocked. The block can be deactivated by
switching the controller off and on.
Flue Gas
temperature limit:
With the corresponding parameter the permitted limit for the flue gas temperature
can be entered according to the default values of the heat generator manufacturer
and serves as the reference value for the sequential functions described above.
Recommended Setting:
Nominal flue gas temperature as per manufacturer plus 10 ... 20 K.
8.1.11 Charging pump (CHP)
Note: Function active only if the function "charging pump" was assigned in the "Hydraulic"
menu to one of the outputs "Direct circuit pump", "Variable output 1" or "Variable
output 2".
Function: For each heating and DHW demand a charging pump is active with the heat
generator for the supply of the remote heat consumers.
Bus system: A charging pump with bus address 10 connected to the standard unit runs as soon
as there is demand for the data bus (all heating and DHW circuits included).
A charging pump connected to an add-on controller (address 20, 30,...) only runs on
demand by the heating circuits of the corresponding controller.
CHP extended
running time:
If there is no longer a demand to the heat generator the charging pump switches off
with time delay in order to avoid a safety switch-off of the heat generator at high
temperatures.
