8.15 Boiler
Release below outside temp
(2203)
The boiler is only put into operation if the mixed outside temperature is below
the threshold set here. The switching difference is 0.5°C.
Full charging buffer
(2208)
Under Prog. no. 4810 (full charge charging buffer) is selected, whether and when
the charging buffer is fully charged despite automatic heat generation lock. Un-
der Prog.no. 2203 it is set, whether the boiler takes part in the full charge or not.
- Off: the boiler does not take part in the full charging of the charging buffer.
- On: the boiler takes part in the full charging of the charging buffer.
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 dif-
ference is increased by 50 %. However, this setting does not guarantee that the
burner 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 overrun time
(2250)
Pump overr time after DHW
(2253)
The delay times of the pumps are controlled according to heating mode or DHW
mode.
Boiler pump at heat genera-
tion lock
(2301)
Stop of boiler pump in case of activated manual heat generation lock (e.g. via H1).
- 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.
