3. Setup and Installation

The Potterton EP2 Programmer is designed for straightforward installation, particularly when replacing an existing EP series programmer. It utilizes the same backplate, eliminating the need for complex rewiring.

3.1 Compatibility

This programmer is a direct replacement for the following models: EP2000, EP2001, EP2002, EP3002, and EP6002. It is compatible with their existing backplates.

3.2 Installation Steps (General Guidance)

1. Safety First: Before commencing any electrical work, ensure the mains electricity supply to the heating system is completely switched off at the consumer unit/fuse box.
2. Remove Old Programmer: Carefully detach the old programmer from its backplate. Note the wiring connections if you are not replacing an identical model, though for direct replacements, this step is simplified.
3. Mount New Programmer: The EP2 programmer attaches to the existing backplate using a single screw. Align the new programmer with the backplate and secure it firmly.
4. Restore Power: Once securely mounted, restore the mains electricity supply.
5. Initial Setup: The programmer will typically power on and display the current time. You may need to set the correct time and date if it's not automatically maintained.

4.1 Setting the Time and Date

Upon initial power-up or after a prolonged power cut, you may need to set the current time and day. Refer to the specific instructions in your product's detailed manual for the exact button sequence, as this can vary slightly between models.

4.2 Programming Heating and Hot Water Schedules

The EP2 allows for independent programming of Central Heating (CH) and Domestic Hot Water (DHW). You can choose from three programming modes:

• 24 Hour: The same schedule repeats every day.
• 5/2 Day: One schedule for weekdays (Monday-Friday) and another for weekends (Saturday-Sunday).
• 7 Day: A unique schedule can be set for each day of the week.

For each channel (CH and DHW) and each day/period, you can typically set up to three ON/OFF times. Consult your full manual for detailed steps on entering programming mode and adjusting times.

4.3 Manual Override Functions

The programmer includes buttons for temporary manual control:

• ADV (Advance): Pressing this button will either bring on the heating/hot water if it's currently off, or turn it off if it's currently on, until the next programmed event.
• EXT (Extend): This function allows you to extend the current ON period for a set duration (e.g., 1 hour), useful if you need heating or hot water for longer than programmed.

The specific operation of these buttons and any associated indicators will be detailed in your product's comprehensive user guide.

5. Maintenance

The Potterton EP2 Twin Channel Programmer requires minimal maintenance to ensure its longevity and optimal performance.

• Cleaning: Wipe the unit periodically with a soft, dry cloth. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the display or internal components.
• No User-Serviceable Parts: The programmer contains no user-serviceable parts. Do not attempt to open the casing or perform any repairs yourself. Refer any issues to a qualified technician.
• Power Supply: Ensure a stable 230V AC power supply. Fluctuations or interruptions can affect performance. The unit is designed to maintain clock settings during power failure.
