6.1.1.9 SINGLE STROKE
This is a maximum single stroke (opening or closing) that the valve may make during one temperature sampling. If the
temperature is close to the pre-set value, the stroke is calculated on the basis of the proportionality coefficient parameter value.
The smaller the single stroke, the more precisely the set temperature can be achieved. However, it takes longer for the set
temperature to be reached.
6.1.1.10 MINIMUM OPENING
The parameter determines the smallest valve opening. Thanks to this parameter, the valve may be opened minimally, to
maintain the smallest flow.
NOTE
If the minimum opening is set to 0% (completely closed), the pump will not work when the valve is closed.
6.1.1.11 PROPORTIONALITY COEFFICIENT
Proportionality coefficient is used for defining valve stroke. The closer to the pre-set temperature, the smaller the stroke. If the
coefficient value is high, the valve takes less time to open but at the same time the opening degree is less accurate.
The following formula is used to calculate the percent of a single opening:
�������������� ���� ������������ �������������� = (������������ ��������. −������������ ��������. ) ∙
6.1.1.12 CALIBRATION
This function enables the user to calibrate the valve at any time. During this process, the valve is restored to its safe position –
in the case of CH valve it is fully open whereas in the case of floor valve and cooling it is closed.
6.1.1.13 ADDITIONAL SENSORS
When two mixing valves are used, this function enables the user can select the sensors which will provide temperature data for
the valve (for external and return temperature sensors). Temperatures can be read from the sensors of a given valve (own) or
the sensors of valve 2 (from module 2).
6.1.1.14 TEMPERATURE CONTROL
This parameter defines the frequency of water temperature sampling (control) downstream of the CH or DHW valve. If the
sensor detects temperature change (deviation from the pre-set value), the electric valve closes or opens appropriately (by the
pre-set stroke) to restore the pre-set temperature.
6.1.1.15 VERSION
This function enables the user to check the software version of the subordinate module.
6.1.1.16 VALVE REMOVAL
This option is used to remove the valve from the controller memory. Valve removal is used e.g. while disassembling the valve or
replacing the module (re-registration of a new module is necessary).
6.1.1.17 FACTORY SETTINGS
When factory settings option is activated, all customized settings of the CH boiler (saved in user's menu) are lost and replaced
with factory settings. Then, the parameters may be customized anew.
6.2 R . .
OOM REG TEMP LOWER
The user defines the temperature value by which the pre-set CH temperature will be reduced when the pre-set room regulator
temperature is reached.
