Hi

Last night we have a small power outage which has thrown the above CH
unit into a confused state. The CH has been running okay, but we have
just realized the position and would like enlightenment on two chance
discoveries:

In its new "mode", it now seems able to accept three time periods of
operation and not the original two.

The CH has been working okay without the need for the hot water to be
activated too.

So, two questions:

1) Is it likely that the original installers didn't configure the unit
correctly, and we can running the CH without necessarily having the HW
boiling too?

2) Can we switch it permanently into 3 time periods a day somehow?

The unit has now been reset, because the power outage caused other
problems with the unit.

any help appreciated
Rachel

I'm afraid you haven't provided anything like enough info for help to be
attempted.
e.g. type of system, 2 or 3 port valves, programmer etc

I've found that ours (without a backup battery at the moment) often locks
when power is applied after a short period. Longer periods of it being off
seem to be okay. On the back there is are 2 switches - I can't remember
exactly what they're labeled, but certainly one of them appeared to imply it
was 2 or 3 switchings per day. So far though, I think I've tried it on 3
but never had showing on the display.

Its possible that the LCD dispay (likely to be common to a number of models
with different abilities) got confused and displayed the 3rd switching
period but the controller doesn't actually do 3 switching periods.

The unit has now been reset, because the power outage caused other

I presume it just reset it into it's default on/off values. This also
probably means that the backup battery is buggered and requires changing

In its new "mode", it now seems able to accept three time periods of

See below

I can't remember if it has 2 or 3 on/off periods, but if you now have 3,
it seems likely that whoever set the timer last overran the second
on/off by the first or second.
Whether the CH and HW are linked together is determined by a cam which
can be rotated by removing the timer from the backplate and rotating it
with a small screwdriver

Replacement batteries can be obtained from CPC for several quid (part no
BT00052 or something like that)

It's not the display that might be confused, the controller inside
might. There are a whole series of EPs ..2000, 2001, 3000, 3001 up to
6000, with various functions enabled.

EP2001 definately has 2 time periods Mon-Friday and two for the weekend.
Designed for Hw, Ch or combined HW+CH operation.

Aren't those the ones where the different (and differently priced) models
have different, easy to solder, jumpers on the PCBs? :-)

Thank you to all who replied. I'll have a look at the cam and any
switches that may be found on the back of the unit.
