Table 7.2 Effective burner anti-cycle time

The burner is electronically locked for a specific time 
after each time it is switched off ("re-start interlock") 
to avoid frequent switching on and off of the burner 
(energy losses).
The burner anti-cycle time is only activated for the 
heating operation. Hot water operation during a burner 
anti-cycle time does not affect the timer.
The individual anti-cycle time can be matched to the 
hydraulic and thermal properties of the heating installa-
tion. In the factory the burner anti-cycle time is set to 
a value of 20 minutes. It can be varied under diagnosis 
point "

d.02

" within the range 2 minutes to 60 minutes. 

The individual effective anti-cycle time is calculated 
from the momentary target feed temperature and the 
set maximum burner anti-cycle time.
The timer can be reset or cancelled by actuating the 
appliance main switch. The remaining burner anti-cycle 
time left after switching off by the controller in heating 
operation can

 

be

 

called up under diagnosis point "

d.67

".

The individually effective burner anti-cycle times with 
respect to the feed temperature and the maximum set 
burner anti-cycle time can be taken from Table 7.2.

7.2.6  Determination of the maintenance interval/

maintenance display

The electronics of the ecoTEC exclusive allow you to 
determine the maintenance intervals for the appliance. 
This function serves to provide a signal that, after a 
specific, adjustable, number of burner operating hours, 
the boiler needs to be serviced. The service signal 

SEr

 is 

shown in the display of the ecoTEC exclusive alternately 
with the current pressure after expiry of the set number 
of burner operating hours. The display also appears on 
the VRT 360 and 400 (accessories).

upon the type of appliance)

3.100 h

Table 7.3 Guide values for operating hours

The operating hours to the next service can be set under 
diagnosis point "

d.84

". Guide values can be taken from 

Table 7.3; these values correspond to an approximate 
operating time for the appliance of one year.
The operating hours can be set in steps of ten from 
0 to 3000 h.
If there is no number in the diagnosis point "

d.84

", but 

there is the symbol "

-

", then the "maintenance display" 

is not active.

h

 Note!

After the set number of hours have expired, the 
service interval must be entered in the diagno-
sis mode again.
