two switching heat generators via the burner relays
A6 and A7.
Switch on the 1st Burner stage when temperature drops
below set temperature of the heat generator.
Switch off the 1st burner stage when the temperature
setting is exceeded by the HYSTERESIS.
Switch on the 2nd burner stage
- after start of 1st Burner stage and
- undercutting the set temperature by 5K
(= Start the BLOCK-TIME)
- and progress of the BLOCK-TIME
(= Release 2nd burner stage)
Switch off 2nd burner stage when the temperature setting
is exceeded by the HYSTERESIS.
Switch 2nd Burner stage when temperature drops below
set temperature of the heat generator.
Switch off the 1st burner stage when 2nd stage enabled
after set temperatures are exceeded by [HYST
