Charging temp max
(5050)
With this setting, the maximum charging temperature for the connected storage
of the solar system will be limited. If the DHW-charging value is exceeded, the
collector pump switches off.
The collector pump can be re-activated by the collector overheating protecting
function see prog.no. 3850) until the storage safety temperature has been rea-
ched.
Recooling temperature
(5055)
Setting the temperature for recooling the DHW-storage.
Recooling collector
(5057)
Recooling of the overheated collector through giving off of the energy to the sur-
rounding of the collector.
El imm heater optg mode
(5060)
- Replacement : the DHW is only heated by electrical immersion heater if the boi-
ler signals a malfunction or a boiler lock exists.
- Summer : the DHW is heated by an electrical immersion heater if all connecting
heating circuits have switched to summer mode. As soon at least one heating
circuit is switched to heating mode, the DHW preparation is again taken over
by the boiler. The conditions listed for the electrical immersion heater under Re-
placement operating mode is also activated in the Summer operating mode.
- Always : the DHW preparation is only performed by the electrical immersion
heater.
Electrical immersion heater
release
(5061)
- 24h/day : Permanent release of the electric insert
- DHW release : Release of the electric insert depending on DHW-release (see
prog.no. 1620).
- Time programme 4 : Release of the electric insert via the time switching pro-
gramme 4 of the local controller.
Electric insert control
(5062)
- External thermostat : The storage temperature will be achieved with an external
thermostat without setpoint control of the controller.
- DHW sensor : The storage temperature will be achieved with an external ther-
mostat with setpoint control of the controller.
Automatic-Push
(5070)
The DHW-Push can activated by hand or automatically. It causes a one-time DHW
charging to the nominal setpoint.
- Off : The DHW-Push can only activated by hand.
- On : If the DHW temperature drops by more than two switching differences
(prog. no. 5024) below the reduced setpoint (prog. no. 1612), one -time it will
be recharged to the DHW nominal setpoint (prog.no.1610).
The automatic push only works for set DHW operating mode.
Excess heat draw
(5085)
An excess heat draw can be actuated through the following functions: storage
tank temperature maximum, automatic push, charging priority time push, excess
heat draw, active inputs H1, H2, H3 or EX2, storage tank recooling, solid boiler ex-
cess heat draw. If an excess temperature discharge is activated, the excess energy
can be discharged through a heat draw of the room heating. This can be separate-
ly set for each heating circuit.
