The OSF POOLcontrol-30 is a 230V filter control unit with integrated solar control, designed to manage the operation of swimming pool filtration and heating systems. Its primary function is to enable time-dependent switching of a 230V alternating current filter pump according to a user-programmable schedule.
The device controls the swimming pool heater via an electronic temperature regulation system, which operates only when the filter pump is running. An internal interlock automatically switches off the heater during filter pauses, ensuring energy efficiency and safety. Users can select the desired swimming pool water temperature from the front panel or switch off the heater entirely. For heating, a floating contact (terminals 22 + 23) and a 230V output (terminals U2 and N) are provided. The unit also supports solar heating, with dedicated terminals for a solar actuating drive (U5 and U6) that manages water flow through solar absorbers.
A key feature is the integrated frost protection function, simplifying winter maintenance. When activated, a temperature sensor connected to terminals 32 and 33 acts as an air temperature sensor. If the temperature falls below 0°C, the filter unit is activated, and the temperature regulation system controls the heater to maintain a set temperature of 3°C. During frost protection, solar temperature regulation is switched off.
The POOLcontrol-30 also offers convenient automatic regulation of the swimming pool water level through terminals for the NR-12-TRS-2 electronic level regulation system (Art. No. 3030075020). This protects the filter pump from damage caused by operating without water.
For backflushing and rinsing, bar valves (230V) can be directly connected to terminals U3, U4, and N, eliminating the need for separate backflushing control units. If a 6-way valve is used, additional terminals for the EUROTRONIK-10 system allow the filter control unit to be extended for automatic filter and backflushing control.
Extra terminals (20 + 21) provide a floating relay contact for connecting additional devices, such as a dosing system. This contact remains closed during filter periods and opens outside these times.
The operational status of the filter pump and heater is clearly displayed by indicator lamps on the front panel, allowing for continuous monitoring.
The front panel features an LCD display that shows the current water temperature and time. Users can select between manual, automatic, or off operating modes using a dedicated key. Indicator lamps next to this key display the selected mode.
Pump indicator lamps show the filter pump's status: off (no light), in operation (green), or temporarily switched off by the EUROTRONIK-10 backflushing controller or NR-12-TRS-2 level regulation system (red).
Heater indicator lamps display heater operation: off (no light), in operation (green), or additional heater blocked (red). A dedicated key allows users to block or release the heater. If a solar sensor is connected, a separate indicator lamp shows the solar heater's operating status. Another lamp indicates when backflushing with a bar valve is in progress.
Temperature selection is straightforward: users press a key, then use arrow keys to set the desired swimming pool water temperature between 0°C and 40°C. The setting is saved automatically after a short period of inactivity or by pressing the key again.
The device allows setting the current time and programming up to ten switch-on and switch-off times for the filter pump. These times are entered in pairs, with minute and hour settings adjusted using arrow keys. Programmed times can also be deleted.
Backflushing can be programmed by setting the duration for backflushing and rinsing, as well as the start time for the rinsing process. The system allows for manual triggering of backflushing by pressing a key for an extended period.
An "Info" key provides access to diagnostic information, including the program version number, solar temperature, water temperature, operating statuses for the filter pump, solar heater, and additional heater, as well as operating hours counters for each. Language settings can also be adjusted.
The device includes an electronic control system protected by a 0.25A fine-wire fuse on the internal PCB. Short-circuit protection for the filter pump requires a backup fuse of maximum 16A on site.
A service terminal (Art. No. 3010000900) can be connected to the control system for optimal settings, initial startup, and fault diagnosis. This socket is located on the PCB inside the device. Crucially, the control system must be isolated from the mains before opening the housing and plugging in the service terminal.
The service terminal displays various operating modes and parameters, including filter unit operation mode (off, operation, run-on time, forced switching, priority circuit, pump blocked, backflushing, rinsing, frost protection mode), heater operating mode (controller off, additional heater off, heater blocked, temperature reached, additional heater on, solar heater on, frost hazard), water temperature, and solar temperature.
The water and solar temperature displays can be readjusted using adjusters on the printed circuit board if they do not match the actual temperatures. Turning the adjuster clockwise increases the displayed value. "Sensor break" or "-----" indicates a defective sensor. It is critical that if both temperature sensors are at the same temperature, the solar sensor must never display a higher value than the water temperature sensor, otherwise the solar heater will not switch off. This balancing should only be performed by a trained service technician.
The service terminal also allows adjustment of the "Solar difference" (how much warmer the solar collector needs to be than the pool water before the solar heater switches on), "Solar additional temperature" (how much the pool set temperature can be exceeded during solar heating), and "Limit temperature" (maximum temperature at which the solar heater automatically switches off for safety).
Minimum switching on/off durations for the additional heater and solar heater can be set to avoid too short switching periods, influencing the temperature regulator's behavior. The "Filter pump run-on time" can be adjusted to determine how long the filter pump runs after the additional heater switches off.
Operating hours counters for the filter pump, additional heater, and solar heater are available. Backflushing counters (internal for bar valves and external for EUROTRONIK-10) track the frequency of backflushing processes.
The service terminal also provides information on "Forced switch-on of NR-12-TRS-2" and "EUROTRONIK-10 backflushing signal," indicating whether these systems are actively switching the filter pump. "Interlocking" displays whether the filter unit is switched off by external systems (EUROTRONIK-10, NR-12-TRS-2, or coil earthing contact).
"Heater priority circuit" and "Solar heater priority circuit" settings determine if the temperature regulation system can override filter time settings to switch on the filter pump and heaters outside scheduled filter times. These priority circuits can be switched on or off via the service terminal.
Finally, the service terminal allows for manual activation of output relays for the filter pump, solar operation, heater, dosing unit, backflushing valve, and rinsing valve, aiding in testing and troubleshooting.
