Loading start temperature
Parameter buffer loading start temperature defines high temperature
below which buffer feeding starts. Buffer feeding proces is finished
when low temperature reaches value defined in parameter buffer
feeding end temperature.
Loading end temperature
Start heating system
The temperature below which the heating system is deactivated,
measured at the upper part of the buffer.

MIXER SERVICE SETTINGS
Mixer support
x
Off
Mixer servomotor and pump are not active
x
CH on
Applicable when mixer cycle powers heating installation of CH.
Maximum temperature 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
x
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.
x
Pump only
When mixer cycle temperature exceeds value set in parameter
Preset
temperature of mixer
, feeding of mixer pump is stopped. After
decreasing temperature of circuit by 2 degrees C
–
pump is
reactivated. This option is normally used to control floor heating pump
in situation when it cooperates with thermostatic valve without
servomotor. By such action is not recommended. It is recommended
to use standard heating cycle in floor heating, which consists of valve,
servomotor and mixer pump.
Thermostat selection*
Parameter available only after connecting to room panel Room
Control TOUCH. This option allows change of room thermostat for
mixer cycle. Options available:
x
Universal
–
standard thermostat connected to terminals 28-30 for
mixer 1, for mixers 2,3,4,5 use proper terminals in additional
modules.
x
ecoSTERT1
–
thermostat 1 in Room Control,
x
ecoSTERT2
–
thermostat 1 in Room Control,
x
ecoSTERT3
–
thermostat 1 in Room Control,
If Room Control TOUCH is not connected then the controller
cooperates with standard room thermostat.
Minimum mixer temperature
Using this parameter it is possible to restrict Chance of setting to low
preset mixer circuit temperature. Automatic control (i.e. periodical
temperature reduction) also will not cause reduction in preset
temperature below value set in this parameter.
