A timer to automate the swimming pool’s opening hours

A module’s timer is designed to control the operating times of equipment fitted within a swimming pool control panel.

It allows you to set on and off times to tailor the system’s operation to the needs of each swimming pool, thereby avoiding the need for the professional or user to carry out this task manually every day.

Its compact design makes it particularly useful as a component in electrical panels or as a replacement for an existing timer switch, provided that the electrical specifications and connection system are compatible.

Scheduling in 30-minute intervals

The programmer allows you to organise the operating schedule using 30-minute intervals.

This division makes it easier to set one or more work periods throughout the day, depending on the specific capabilities of the mechanism.

It can be used, subject to checking the wiring diagram, to programme systems such as:

• Filtration circuits.
• Swimming pool pumps.
• Lighting.
• Auxiliary equipment.
• Treatment systems.
• Other circuits controlled from the switchboard.

Compatibility with each piece of equipment will depend on the voltage, the type of load and the capacity of the timer’s contacts.

Application in swimming pool electrical panels

Trypool classifies this product as a spare part for swimming pool electrical panels. It is primarily intended for:

• Repair of existing panels.
• Replacement of faulty timer switches.
• Upgrade of the scheduling system.
• Installation of new electrical panels.
• Time-based automation of auxiliary equipment.

Before replacing the existing clock, you must check that the new model has the same electrical specifications and a compatible wiring diagram.

Compact single-module design

The module’s design helps to reduce the space it takes up inside the electrical cabinet.

However, before placing your order, please ensure the following:

• Actual physical width.
• Fastening system.
• Available depth.
• Terminal positions.
• Number of cables connected.
• Wiring diagram.
• Compatibility with the existing frame.

The term “a module” does not, on its own, specify all the installation details.

Selection based on the team being managed

A clock should not be chosen solely on the basis of its size.

The installer must check:

1. Supply voltage.
2. Permissible intensity.
3. Output contact type.
4. Power and nature of the load.
5. Number of channels.
6. Type of programme.
7. Minimum manoeuvring distance.
8. Presence or absence of a power reserve.
9. Compatibility with contactors.
10. Environmental conditions of the painting.

When the load exceeds the clock’s capacity, a contactor is usually used to carry out the operation. However, one should not assume that this model is capable of handling it until one has its specific data sheet or circuit diagram.

Replacing a swimming pool timer

If you wish to use it as a replacement part, we recommend that you first identify the programmer currently installed.

It is a good idea to take a photo or make a note of:

• Brand and reference number.
• Voltage.
• Terminal numbering.
• Diagram printed on the side.
• Rated current.
• Number of modules.
• Type of programme.
• Role within the organisation.

It should not be substituted simply because both products look similar or are of a similar width.

Professional installation – Pool timer

Installation must be carried out by qualified personnel, with the switchboard completely disconnected from the mains supply.

The professional must:

• Check that there is no voltage.
• Check the wiring diagram.
• Identify the power supply and output.
• Check that the terminals are tight.
• Set the current time.
• Set the operating periods.
• Check that the equipment is operating correctly.
• Make sure you close the box properly.

Specific wiring instructions should not be published without the official diagram for this model.

Use in filtration systems

One of the common uses of this type of timer is to set the operating times for the filtration system.

The filtration time should not be determined solely on the basis of a general rule. It depends on:

• Pool volume.
• Actual flow rate of the system.
• Water temperature.
• Use of the swimming pool.
• A crowd of bathers.
• Type of treatment.
• Water status.

The timer runs according to the set schedule, but does not automatically calculate the required filtration time.

Maintenance – Pool timer

It is recommended that you check the following regularly:

• That the watch keeps accurate time.
• Ensure that the scheduled periods are carried out.
• That there are no loose terminals.
• That there are no signs of overheating.
• That the mechanism is not jammed.
• That the monitored equipment switches on and off correctly.

If the timer loses the time following a power cut, you should check whether the model has a power reserve and whether it is working correctly.
