The Control Unit's Basic Settings; Igniting - Opop H4 EKO-D Series User Instructions

H4EKO-D
The user here sets the daily cycle and pump breaks for 30 minutes. To facilitate setting these parameters, there is a possibility
of copying the selected time interval to other days. Once the operating plan has been established, it is necessary to set the
working time and pump shutdown time during the activity in the previously selected time interval. If necessary, it is also
possible to quickly erase the current settings, thus making it easier to set new time intervals.
12. Rotary switch sensitivity – With this setting we can determine the impulse controller's sensitivity, which detects the correct
fan speed and protects it against damage, in levels from 1 to 3 (where 1 means the highest sensitivity).
13. External sensor calibration – Correction of the outdoor sensor is performed during installation or after a longer operating
time of the controller if the displayed temperature differs from the actual one. Control range: -10 to +10°C.
14. Boiler DHW disinfection – Thermal disinfection involves raising the temperature to the required disinfection temperature,
i.e., at least 60°C throughout the DHW circulation. The purpose of DHW disinfection is the destruction of Legionella
pneumophila, which causes a weakening of the immunity of the organism.
After switching this function on (only in boiler priority mode), the boiler will heat until the disinfection temperature specified
by the user has been reached. The disinfection time parameter specifies the duration of the disinfection (e.g.: 10 minutes).
After that, the boiler returns to normal operating mode.
Once the disinfection is switched on, the disinfection temperature must be reached until the disinfection time is reached.
Otherwise, the function is automatically deactivated.
15. Factory settings – Resets the installation menu items to factory settings.
16. PID supervision – In case of reaching the set CH temperature, the boiler enters the so-called supervision mode. In this mode,
the fan is deactivated to prevent power build-up. Attention: The boiler must be installed with a buffer tank so as not to
overheat the water in the heating system and the boiler.
17. Display contrast – Change of the font saturation on the boiler control unit display.

14. THE CONTROL UNIT'S BASIC SETTINGS

When commissioning the boiler, it's necessary to select the correct boiler output. The power is set by the technician installing the
boiler in the control unit's Service Menu. Ensure that the boiler output is set correctly so that the fan speed matches your boiler
output.
The maximum boiler temperature can be set by pressing the navigation key and selecting 'CH temperature'. This temperature will
be maintained by the boiler and the fan will be deactivated after the CH temperature is reached.
Boiler performance is affected by external factors such as chimney draft, primary and secondary flaps, fan speed, fuel
type, correct or incorrect power output calculated by the designer. Therefore, the set CH temperature may be exceeded.
For this reason, it's necessary to install it with a buffer tank.
The maximum DHW temperature, if DHW heating is activated, can be set by pressing the navigation key in the 'DHW temperature'
item. You activate the DHW heating in the 'Pump operating modes' settings. If you activate the DHW heating, make sure that the
DHW sensor is connected, otherwise there will be an alarm message.
