Stop temperature.

If the top buffer temperature drops below this value, in order to save
electrical power, the mixer pumps and HUW pumps will be
deactivated. This function is particularly useful when working in
GRATE mode.
15.5 MIXER
Mixer 1-4 settings
Mixer suport

Off The mixer actuator and pump are not in operation.

CH On
It is being used when a mixing circuit is loading a heat installation of
CH. The maximum mixing circuit temperature is not being limited, the
mixer is fully opened during alarms e.g. with boiler overheating.
Attention: do not use this option when the heat installation is made
with pipes not resistant for high temperatures. In such cases it is
recommended to set the mixer operation for FLOOR switched on.

Floor On
It is being used when the mixer circuit is loading floor heating
installation. The maximum mixer circuit temperature is limited to the
value of max. mixer set temperature.
Attention: after choosing the option
– FLOOR switched on the
parameter of max. mixer set temperature should be so edited, that the
floor heating will be not damaged and there would be no danger of
scalding.

Pump Only
By the moment when the mixer circuit temperature exceeds the set
temperature in the parameter mixer set temperature, the mixer pump
supply will be shut down. When the circuit temperature will drop by
2˚C then the pump will again be switched on. This option is usually be
used for control of floor heating pump in situation, when this pump is
operating together with thermostatic valve without actuator.
Thermostat select*
Options to choose from:
Shut down: (it cuts the influence of room thermostat upon the boiler
operation.)
Universal: (it turns on the no/nc room thermostat coupled to 42-43
contacts, it is required to use thermostats with 1K hysteresis.)
ecoSTER: (this option is available after remote control device
ecoSTER TOUCH is being connected, thermostat signal is being send
from room panel.)
Minimum mixer temperature
It is the parameter used for limitation of choosing too low value of set
mixer circuit temperature by the user. Automatic regulation (e.g.
periodic temperature reduction) also does not cause the reduction of
set temperature value below the value given in this parameter.
Maximum mixer temperature
This parameter has two functions:
_ it enables the limitation of choosing too high value of set mixer
temperature by the user. Automatic regulation (correction upon
heating curve, that comes from outside temperature) also does not
cause crossing the set temperature above the value given for this
parameter.
_ when the
Mixer Support = On , then the mixer pump will shut down
by max. mixer temperature +5˚C, which protects the floor against
destruction. For the floor heating it should be set for the value below
45+/-
50 ˚C or even lower, when the thermal resistance of this floor is
lower. Attention: setting too lower value of this parameter can lead to
unnecessary shut down of the pump.
Valve opening time
The time of valve full opening should be entered
– this time can be
read from the nameplate of valve actuator, e.g. 140s.
Proportionality range
This parameter affects the movement of the mixer actuator. Increasing
this value results in the mixer reaching the set temperature faster.
Setting this parameter to excessive values causes deregulation of the
