HA minimum limit
(not in cascade operation)
Reduces condensate formation in the HA when demand for
heat is low. Shut-off of the HA takes place in all cases at the
earliest when HA minimum temperature (HA1 min temp.) +
Hysteresis (5K) is reached.
00 = minimum limit on heating curve
The HA switches on once the temperature falls below that
required by the consumers.
01 = minimum limit if demand exists for heating
If demand exists for heating (pump enabled), the HA main-
tains at least the set minimum temperature
HA1 min temp.
02 = permanent minimum limit (24h)
The HA maintains the set minimum temperature (HA1 min
temp.) for at least 24h.
Hysteresis *) 5 - 20K 5K
Function to optimise heating appliance operation at various
levels of demand.
After the burner is switched on, the effective switching
hysteresis is reduced linearly from the set hysteresis to the
minimum hysteresis (= 5K) during the hysteresis period
“Hyst. period”.
Low heat transfer
In this case, the hysteresis which is set higher is effective.
This prevents short runtimes and frequent synchronising of
the burner.
High heat transfer
In the case of extended burner operation (high heating load),
the hysteresis is automatically reduced to 5K. This prevents
the heating appliance from heating up to unnecessarily high
temperatures.
Hysteresis period *) 0 - 30 min 10 min
Clock inhibition *) 0 - 30 min 0 min Idle time of the second burner stage
Burner 2 hyst. *) 2K - 20K 2K
Hysteresis for second burner stage
Switches on the 1st burner stage if the temperature of the
heating appliance falls below the target temperature.
Switches off the 1st burner stage if the target temperature is
exceeded by the HYSTERESIS.
Switches on the 2nd burner stage
- after the 1st burner stage starts
- and the temperature falls below the target by 5K
(= start the idle time / enable 2nd burner stage)
- and the idle elapses
Switches off the 2nd burner stage if the target temperature is
exceeded by the HYSTERESIS.
Switches the 2nd burner stage back on if the temperature of
the heating appliance falls below the target temperature.
Switches off the 1st burner stage when the 2nd stage is
enabled
after the target temperature has been exceeded by
[HYSTERESIS + BURNER 2 HYST.]
