Measures required in addition to dosing with Bayrosoft ® Before putting the system into operation, administer a shock chlorination using 25 g of Chlorifix per cubic metre of water. The chlorine should act for at least 3 days. A lined swimming pool with a new liner must be treated with chlorine for at least 14 days during which the chlorine level must be kept constant at over 3 mg/l.
Pool Relax Bromine Bring the pH value of the pool water to 7.2. You can manually dose the pH to do so (see "pH measuring and control module"). If the pH value differs widely from 7.2, you can use pH-Minus/pH-Plus in a granular form (it is important that you follow the dosing instructions on the product package).

mV (redox potential) settings Parameter Purpose / effect Setpoint mV The desired or determined mV value of the swimming pool water. Initially, an approximation can be achieved by working with the preset default value. However, to precisely maintain the desired chlorine content in the swimming pool water, the value must be determined for that particular water.
Redox electrode calibration The Pool Relax redox electrode must be calibrated once every three months to compensate for any deviations in its measurement behaviour. The electrode must be replaced once a year. These maintenance and replacement intervals absolutely must be complied with to ensure that measurements are correct and that water quality is at its best.
10.2 Temperature configuration For the Pool Relax Chlorine and Pool Relax Bromine the temperature measurement is unused. For the Pool Relax Oxygen, temperature measurement is active and used for the calculation of the temperature compensation (refer to the description of the O2 module).

11.5 Intermediate dosing In the course of the week that passes until the next main dosing, the amount of effective Bayrol in the water will decrease steadily. Product attrition accelerates at higher temperatures. To compensate these effects and to ensure that the optimal amount of Bayrol is always in the water, intermediate dosing takes place after the first third and the second third of the week.
Example: If the dosing day is set to "Friday", the following dosing times apply: Main dosing on Fridays at 00:00 First intermediate dosing on Sundays at 08:00 Second intermediate dosing on Tuesdays at 16:00 Trend of effective Bayrosoft concentration in water ®...
Alarm monitoring 12.1 Overview Pool Relax continuously monitors all relevant data and operating states to ensure correct operation and good water quality. If Pool Relax discovers a problem, it generates an alarm message that points to the problem. Some alarm conditions block product dosing until the alarm is eliminated.
12.2 Flow alarm Pool Relax offers two different variants for monitoring the flow alarm. Automatic quitting of the flow alarm (default variant) In this variant, Pool Relax evaluates a flow alarm not as a fault but as a normal operating state. In most swimming pool systems, circulation does not take place around the clock but is only switched on intermittently.
The alarms are displayed on the alarm page as follows: Level Alarm pH Quit A new alarm occurred. The alarm cause has not yet been eliminated. The alarm has also not been quit, which is why the quit button is displayed. Level Alarm pH The alarm cause has not yet been eliminated.
Service messages 13.1 Overview The Service Messages function enables precise planning of certain service procedures: Calibration (pH, mV, T) Recommended interval: pH, mV 3 months / temperature 12 months Electrode replacement (pH, mV) Recommended interval: 12 months Hose replacement at dosing pump (pH, mV, O2) Recommended interval: 12 months For each service procedure, a time interval in months can be specified in the "Service Intervals"...
Event log 14.1 Overview The event log records all important events concerning Pool Relax. It is an important aid in monitoring the correct operation of the swimming pool system and analysing possible problems. The event log can be opened from the main menu. It records up to 100 events with date and time. The following events are recorded: ...
Manual dosing 15.1 Overview For the pH, mV and O2 modules, an additional amount of care product can be added to the swimming pool water at any time by means of manual dosing. Manual dosing is time-limited and is automatically ended after the selected dosing duration. In addition, manual dosing can be stopped any time.
During dosing, the menu display changes. Only the data relevant to the dosing in progress are displayed: Current measured value pH / mV Remaining time of manual dosing in minutes The amount already dosed in litres for the manual dosing in progress. ...
Add-on Modules 16.1 Universal switch outputs Overview Pool Relax offers up to four universal switch outputs that can be used to control additional attractions, e.g. pool illumination or a jet system. The terminals „OUT1“ or „OUT2“ are used for the switching functions. In addition to that, the outputs “OUT3 (pH+)“ and „OUT4 (Alarm)“ can also be used for switching functions, if they are not needed for pH+ dosing or as alarm relay, respectively.
Extra pump Cl (Pool Relax Chlorine only) The output is switched on as long as chlorine is being dosed, i.e. as long as the mV (redox) dosing rate is not at 0%.
