11. Buttons
E On/Off - activates/deactivates the dosing function
F Flow - pressed button shows the current flow through the MiniMaster flow cell.
F+G Calibration
G Forced dosing - pressed button for 3 seconds causes forced dosing for 2 minutes of chlorine or 30 seconds for pH
(rolling LEDs). If an ongoing forced dosing needs to be discontinued early: press button (E).
12. Change of factory settings
Time-Out – exceeded dosing time
The time-out function is a built in safety catch in the software and is a limit on continuous dosing time.
The function is factory set and shuts off the dosing and triggers an alarm after 90 minutes of continuous dosing. This is to prevent
unreasonable dosing, which can occur in the event of e.g. leakage or measurement error.
If the dosing equipment needs more than 90 minutes of dosing to achieve the correct values, the Time-Out function can be
deactivated, see below.
When the power to MiniMaster is turned on, a start sequence is triggered after about 2 seconds and the LEDs (1-7) are lit in
sequence, thereafter the set mode is shown (see point 5 below).
Deactivation of Time-Out (only the chlorine unit)
1. Switch off power to MiniMaster.
2. Switch on the power.
3. Press button E when LED 1 turns on, release when LED 2 turns on (respective LED blinks 2 times/second).
4. Press button E when LED 6 turns on, release when LED 7 turns on.
5. When the start sequence is done, the set mode is confirmed with a blinking indication:
‒ LED no. 3, 4 and 6 blink = deactivated Time-Out (‒ LED no. 3, 4 and 5 blink = activated Time-Out).
Save the setting by holding in button E for 3 seconds directly after finished confirmed LED indication (blinks 5 times) until
LED 1 or 7 blinks rapidly.
6. To check which setting the unit has: turn off, wait approx. 3 sec., turn on power to the unit ‒ LED 1 to 7 blinks during the start
sequence with ensuing blinking indication as per point 5.
7. To activate the Time-Out function again, repeat from step 1.
NOTE: If Time-Out is deactivated an extended period of time and a fault arises, an unlimited amount of chemicals can be dosed
into the pool or leak out in the machine room. Always check hoses, connections and chemical levels regularly and ensure that
Time-Out is activated.
Dosing setting (acid or alkali)
Dosing function of pH-reducing agent (acid) is factory-set on the pH unit.
When the power to MiniMaster is turned on, a start sequence is triggered after about 2 seconds and the LEDs 1 to 7 are lit in
sequence, thereafter the set mode is shown, see point 5 below.
If you instead want to dose alkali for a pH-increasing effect, a resetting must be done as per below:
NOTE: This only applies to the pH unit and pH calibration must be done before this change is begun.
Resetting to dosing of Alkali (only the pH unit)
1. Switch off power to MiniMaster.
2. Switch on the power.
3. Press button E when LED 1 turns on, release when LED 2 turns on (respective LED blinks 2 times/second).
4. Press button E when LED 6 turns on, release when LED 7 turns on.
Meaning
The unit is not calibrated. Dosing is not possible.
Flow too high or too low. Dosing is deactivated.
Measurement ongoing, dosing mode is activated.
Measurement ongoing, dosing mode is not activated.
Forced dosing is in progress.
