7.0 Programmer
NOTE: The programmer provides up to three ON/OFF
periods each day. If you do not want to use all these, a
switch period can be cancelled by programming the ON
operation for the same time as the OFF operation e.g.
2nd ON at 12.00 pm and 2nd OFF at 12.00 pm. When
the 3rd OFF time has been entered the programmer will
display the word COPY and the DAY OF THE WEEK
INDICATOR will flash (see Fig.15).
If required these ON/OFF times can now be quickly
copied so that they apply to any other day(s) you
choose. This avoids separately programming days with
identical switching times eg Monday to Friday. If not
copying press ENTER and press SET button to return
SET INDICATOR to run position.
vi) Use the (+) and (-) BUTTONS to move the DAY OF
THE WEEK INDICATOR to the next day that you wish
the times to apply and press the COPY BUTTON, the
display will indicate 'IN'.
Continue in this way until the programme has been
copied to all the days that you wish it to apply to.

Questions and answers
My boiler is not constantly supplying hot water
There are several possible reasons why your Potterton Promax HE Store Range boiler may not be supplying hot water consistently:
1. Programmer Settings: Ensure the programmer is set to 'DHW ON' during the required periods. If it's not, the boiler won't operate to heat the water.
2. Scaling in Hard Water Areas: If you live in a hard water area, limescale buildup may be affecting the heat exchanger and reducing hot water performance. A water treatment device, such as an ion-exchange water softener, may be needed.
3. Pressure Issues: If the boiler operates in a sealed primary system, ensure the system pressure is correct. Low pressure can affect performance.
4. Flow Restrictors: Using flow restrictors can help prolong hot water availability, especially in systems with smaller storage capacities.
5. Maintenance: The boiler may require servicing or cleaning if components like the heat exchanger are not functioning properly. Ensure the system has been maintained by a competent person as recommended.
6. Expansion Vessel Sizing: If the expansion vessel in the system is undersized or not operating correctly, it could impact performance.
If these steps do not resolve the issue, consulting a qualified service engineer is recommended.
