The purpose of outside temperature disable is to prevent the heat 
generator from starting up above a defined outside temperature. 

If several heat generators are controlled though one device 
(automatic stoker, 2-stage), all stages of the device will be 
disabled with outside temperature disable. 

In the case of cascaded systems with multiple devices, the entry 
of an outside temperature disable is possible for each central 
device so that individual levels can be blocked by the outside 
temperature disable. 

The climate zone is the coldest outside temperature value to be 
expected. 

For the heat demand coverage, this value is taken as the basis for 
the design of the heating system. 

This parameter defines the corresponding slope value of the 
heating curve of the heating circuit with regard to the climate 
zone.

Until now, configuration of the heating curve calculation occurred 
via the values 

•  Climate zone (T

ANorm

) 

•  Slope (S) 

•  Heating system (m value) 

Supplemental to the slope, the setting of the design temperature

 is also possible directly at the controller.
