1.3 Safety instructions

The Dupla pH-Control Pro is designed exclusively for use in enclosed rooms. All electronic components of the device

must only be operated whilst they are free from defects. Should the mains supply be damaged, please please return it

to your dealer for repair. Continued operation of the device may cause fatal injury from electric shock. Ensure that the

control unit and connection strip do not come into contact with water.

Technical products must only be operated as supplied. Electronic components must not be modiﬁed in any way, and

the leads must not be shortened. Covers or housings must not be opened. If the product is damaged cease useage or

shut down immediatly by pulling the mains plug.

1.4 Assembly advice

Control units

The reverse side of the control unit has recesses that are used to lock the fastening rail which is ﬁxed to the wall or

the aquarium cabinet with the screw set. The cable to the control unit has a USB connector so that holes of control

unit dimensions do not need to be sawn out of the terrarium cabinet. The USB connector is not designed for a compu-

ter connection. The control unit has a 2 metre cable which permits installation outside the aquarium cabinet as well

as an unobstructed view of all values and status modes.

Connection strips

The connection strip should be screwed to the back or side panel inside the aquarium cabinet to ensure that there is

no contact with the unit in the event of water leakage.

pH-Eletrode

The Dupla pH-Control Pro system is equipped with a BNC connector for pH electrodes.

2. Description of the basic functions

2.1 Function monitoring of external devices

The housing is ﬁtted with LEDs. In operating mode this indicates the active control of the external device.

2.2 Safety shutdown during programming

When entering into the programming mode, both slots are deactivated for safety reasons.

2.3 Safeguard function

To protect electronic components, a delay of 60 seconds is set between 2 switching states before the respective slot

becomes active again.

2.4 Interval reset

Irrespective of the time of day, all programmed intervals start when the device is switched on or the menu is quit.

2.5 Return function

The Dupla pH-Control Pro automatically returns to the operating mode when no button has been pressed for a period

of 90 seconds while in the programming mode.

2.6 Memory function

To safeguard against loss of data in the event of a power failure, the Dupla pH-Control Pro stores all set values. The

unit will continue to calculate the time for up to ﬁve hours after such an event, so the clock does not need to be reset

after brief power failures.

2.7 Malfunction displaying

In the event of a pH-Electrode defect will be displayed. A programming error in the timer programming for slot

2 is indicated by E05.

3. Description of the programmable functions

Slot 1 can only be programmed for pH control. Slot 2 can only be programmed for timer switch. In programming

mode, the functions can be conﬁgured in the following sequence.

3.1 Clock programming

3.1.1 Time setting

The factory presets the time at . The time setting however is not cleared during a resetting procedure.

3.2 pH programming

3.2.1 pH set point

The pH set point can be adjusted within the limits of 4.0 - 9.9. If the measured pH value is outside the display range,

values lower than 4.0 are displayed as , values higher than 9.9 are displayed as . Outside of these limits,

the pH channel is switched off. The pH-controlled CO2fertilisation is carried out through permanent measuring by a

connected Dupla pH electrode and switching of a connected Dupla CO2magnetic valve with a switch hysteresis (the

difference between the switching point and the triggering point) of 0.1 pH and a control accuracy is +/- 0.1. Switch

hystereris (the difference between the switching point and the triggering point) is pH 0.1, and the control accuracy is

+/- 0.1 (reference value). In order to ensure the accuracy of measurement and therefore the control circuit, the Dupla

pH-Control Pro provides an optional six-week calibration memory function.

Caution: If no pH electrode is connected to the Dupla pH-Control Pro, so that the BNC socket is open, ﬁctitious

pH values will be displayed.

3.2.2 CO2night function

This enables interruption of the supply of CO2, controlled by a magnetic valve, into your aquarium during the night if

desired. The beginning and end times of the interruption during the night can be choosen after programming the pH

Set point.

3.2.3 pH alarm

A visual alarm indicated by ﬂashing if the temperature exceeds or drops below the programmed desired pH values.

The factory presetting is , which means no alarm. The alarm window can be set between a pH 0.1 and 4.0 deviati-

on from the set point.

3.2.4 Deactivation/activation of the audible pH alarm

The audible alarm can be switched or . The factory setting is , as otherwise an alarm could be trigge-

red immediately when the system is ﬁrst put into service when the electrode is still located outside the aquarium or

not yet calibrated.

3.2.5 Calibrate pH electrode

The factory setting of the calibration points are pH 7, pH 4 and pH 9, the calibration sequence is ﬁrst pH 7, then pH 4

or alternatively pH 9. The calibration process can be cancelled by pressing the ▲and ▼buttons simultaneously.

3.2.6 Calibration reminder function

With this feature enabled, every six-weeks CAL and ﬂash on the display as a reminder to check the pH electrode

calibration. For a period of 10 seconds you will hear a beep every 2 seconds. This will be repeated every hour.

If you prefer not to carry out a calibration, the memory display clears after activating any button and reappears in

another 6 weeks.

In order to calibrate the pH electrode, enter programming mode by pressing the button and follow item 5.2.4 of

the instructions.

To disable of the calibration memory function, continue to scroll through the menu items and set the function to

3.3 Timer programming

3.3.1 Setting the timer control mode

As an alternative to temperature regulation, the second slot can be used to control external devices via a timer switch

with a one-second control interval. Selection is between (external device at slot 2 is permanently activated),

(automatic modus) and (interval mode).

3.3.2 Programme turn-on and turn-off times

If Automatic Mode is selected up to 8 turn-on/turn-off times can be programmed. (The Dupla pH-Control Pro has

an automatic sorting function which will re-arrange the time periods into the correct sequential order when exiting

programming mode.)

3.3.3 Programme interval control

If the Interval mode is selected external devices are switched on for a minimum of 1 second (maximum 23 hrs., 59

min. and 59 sec.) and switched off for a minimum of 30 minutes (maximum 96 hrs. and 59 min.).

3.4 Manual activation/deactivation

Both slots can be turned on and off manually by combination of buttons to be pressed.

3.5 Display light

Factory presetting is an automatic adaptation of the display light. After pressing any button the display light is

switched on. When no button has been pressed for 120 seconds, the display light is automatically dimmed down. It is

possible to change from automatic light dimming to full illumination of the display.
