H4EKO-D
•
Minimum opening – This function sets the valve's minimum opening value. The valve will not close below this value.
•
Equithermal regulation – This function requires the installation of an outdoor sensor. The sensor must be positioned in
such a way that it is not exposed to direct sunlight and other undesirable atmospheric effects. In order for the valve to
work properly, the set temperature (after the valve) is determined for four possible outdoor temperatures.
•
Return protection – The valve can keep the return water to the boiler above the specified limit. Until this is exceeded,
the valve is closed. After reaching the minimum return water temperature, the valve opens and adjusts its position
according to the set temperature on the valve.
•
Boiler protection – If the CH temperature is exceeded above the specified limit in this function, the mixing valve opens
and releases overheated water into the heating system to protect the boiler from high temperature.
•
Opening direction – Select the valve's opening direction according to the electrical connection of the 2 phases of the
valve in the boiler control unit.
•
Valve pump setting – This function allows the user to select the pump operating mode. The pump is switched on:
o
Always (the pump operates continuously, independently of temperature);
o
Above the switch-on limit (the pump switches on above the set switch-on temperature). If the pump is
to be switched on above the switch-on limit, it is necessary to determine the temperature of the pump
switch-on limit (boiler temperature, measured on the CH sensor).
•
Valve type – This function allows the user to set the boiler protection against water that is too cold returning from the
main circulation (water returning from the heating system to the boiler), which can cause low-temperature corrosion of
the boiler. The return protection works in such a way that if the return water temperature is too low, the valve is closed
until the short circulation of the boiler reaches the corresponding temperature. The function also protects the boiler from
dangerously high return temperature by preventing boiling water. When this function is enabled, the user sets the
minimum and maximum permissible return temperature.
•
Room regulation reduction – This function is only active in cooperation with the room controller (standard or RT10).
After the room controller reaches the set temperature in the apartment (it indicates room heating), the valve closes to
lower the temperature behind the valve by the temperature set in this function.
•
OPOP (RT10) controller operation – This option is active only in cooperation with the OPOP (RT10) room controller and
allows to choose an option of the controller's cooperation with the mixing valve:
o
Temperature reduction – in this mode the RT10 room controller, after heating the apartment to the set
temperature, reduces the set temperature of the valve by the value of Room regulation reduction.
o
Dynamic changes – in this mode, the RT10 room controller, after heating the apartment to the set temperature,
works according to the following settings:
•
Set valve temperature change – This setting determines how much the valve temperature decreases or increases when
the room temperature changes per unit. The function is closely related to the Room temperature difference parameter.
•
Temperature control – How often the position of the valve is adjusted based on the change in the current temperature
on the valve.
•
Calibration – Calibration of the valve so that the unit records the limit positions on the valve. The valve opens and closes
automatically. Wait for the calibration to complete and then continue to adjust other valve functions if necessary.
•
Room temperature difference – This setting determines the unit change in the current room temperature (within 0.1°C)
at which the above-described change in the valve temperature occurs.
Example:
Setting: Room temperature difference 0.5°C
Setting: Changing the set valve temperature of 1°C
Setting: Set valve temperature 40°C
Setting: Set room controller temperature 23°C
Case 1: If the room temperature rises to 23.5°C (by 0.5°C), the valve closes at the set temperature of 39°C (by 1°C).
Case 2: If the room temperature drops to 22°C (by 1°C), the valve is set to the set temperature of 42°C (by 2°C).
2. Valve settings, Valve 1 and 2 – This function allows the user to select settings for the operation of the additional mixing valve.
In order for the valve to work properly and in accordance with the user's requirements, it is necessary to configure it by setting
