Potterton EP2000 Programmer replacement

[benny2009]

Hi

I have an old Brown Potterton EP2000 central heating/hot water programmer. However, I wish to update this as I can only switch on CH/HW at the same time or one at a time. Also, the writing on the control panel is almost invisible as it has been operational for over 25 yrs!

I need a direct replacement for my existing model. I have been looking at the various Potterton models and I think the EP6002 would suit me best as it provides for independent heating and hot water control at different times. However, this model only works with a fully pumped system. I am not fully sure whether my system is fully pumped system.

My sysytem basically consists of a Potterton conventional type boiler, a pump, a 3 port diverter valve (Honeywell V4073A1039), a hot water cylinder (which is directly above the boiler), hot water stat, room stat, CH header tank and large water tank in loft.

Can anyone help with the following questions:

1) Is my type of system a fully pumped system?

2) Would the Potterton EP6002 programmer be a direct replacement for
my existing EP2000 model without the need for wiring alterations?

Any help would be appreciated.

Thanks.

Benny.
