Boiler
Setpoint min
(2210)
Setpoint max
(2212)
As a protection function the boiler temperature setpoint can be limited below by
the minimum setpoint (prog.no. 2210) and above by the maximum setpoint
(prog.no. 2212).
Setpoint manual control
(2214)
Temperature, to which the boiler will be contolled in manual control mode (also
see prog. no. 7140).
Burner running time min
(2241)
Here the time span after start up of the burner is set in which the switch off diffe-
rence is increased by 50 %. However, this setting does not guarantee that the bur-
ner always remains in operation for the set time span.
Burner off time min
(2243)
The boiler minimum pause time only takes effect between heating requirements
coming following in sequence. The boiler minimum pause time blocks the boiler
for a set time.
SD burner off time
(2245)
When exceeding this switching difference, the burner pausing time mini-
mum (prog.-no. 2243) will be interrupted. The boiler starts despite pausing time.
Pump after-run time
(2250)
Pump after-run time after
DHW mode
(2253)
The delay times of the pumps are controlled according to heating mode or drin-
king water mode.
Boiler pump at heat generati-
on lock
(2301)
Stop of boiler pump in case of activated heat generation lock.
- Off : Switching off not activated
- On : Switching off activated
Impact heat generation lock
(2305)
With these parameter it can be set whether the heat generation lock should be
effective only for heating requests or also for DHW requests.
- Heating mode only : Only the heating request is locked. DHW requests will con-
tinue to be operated.
- Heating and DHW mode : All heating and DHW requests will be locked.
Temp differential max
(2316)
The limit of the boiler stroke is only possible if a valid value of the boiler return
temperature is available.
Caution! The limit of the boiler stroke is only performed if a modulating heat cir-
cuit pump is configured, i.e. if Prog. no. 6085 (PWM-output P1) is assigned to a
heating circuit pump.
Temp differential nominal
(2317)
The expansion between boiler flow temperature and boiler return temperature is
called the temperature rise.
For operation with a modulating pump, the temperature rise is limited with this
parameter.
