BUFFER SERVICE SETTINGS
Buffer settings
Activating operation
Parameter serves to activating buffer operating mode. Available after
connecting additional module B and buffer temperature sensors.
Loading start temperature
Parameter buffer loading start temperaturę defines high temperaturę
below which buffer feeding starts. Buffer feeding proces is finished
when low temperaturę reaches value defined in parameter buffer
feeding end temperature.
Loading end temp.

MIXER SERVICE SETTINGS
Mixer settings 1,2,3,4,5
Mixer support
Off
Mixer serwomotor and pump are not active
CH on
Applicable when mixer cycle powers heating installation of CH.
Maximum temperaturę of mixer cycle is not limited, mixer is fully
opened during alarms i.e. boiler overheating. Attention: do not activate
this option when installation is made of pipes sensitive to high
temperature. In such situations it is recommended to set mixer service
on FLOOR
Floor on
Is used when mixer cycle powers floor installation. Maximum power of
mixer cycle is limited to value of parameter max preset mixer
temperature.
Attention: After choosing option FLOOR, it is necessary to set
parameter max mixer preset temperature on such a value to not
damage the floor and avoid scalding risk.
Boiler Increase byHUW and Mixer
Parameter determines how high the boiler temperature will be increased
to load HW silo, buffer and mixer cycle. Temperature increase is only
realizing when it is necessary. When preset boiler temperature is at
sufficient level then controller will not change it due to the fact of feeding
the HW silo, buffer or mixer cycle. Increasing preset boiler temperature
during feeding HW silo is signaled with letter “C” in main window of
displayer
HUW operation extension*
Available after connecting HW sensor. After feeding HW silo and
deactivating HW pump may be a risk of boiler overheating. It happens in
case when preset HW temperature was higher than boiler preset
temperature. This issue is exceptionally important in HW pump operation
in SUMMER mode, when pump is deactivated. To cool off the boiler HW
pump operation can be prolonged by
HW operation time prolongation
.
Circulation standstill time
Parameters available after connecting additional module MX.03. Pausing
time between periods of circulation pump operation is defined with value
of parameter
Circulation stop time
(recommended setting 15-40 min.)
Circular pump operates constantly during
circulation operation time
.
(recommended setting 60-120s)
Circulation operation time
Exchanger*
Parameter available after activating option Show advanced setup =
YES. It only refers to hydraulic installation with heat exchanger
between open and closed circuit, point 12.2. Available options:
YES (boiler pump operates constantly in short circuit boiler
–
exchanger, it is not excluded i.e. from SUMMER function or HW
priority)
NO (pump operates normally)
