EPH A27-HW 2 Zone Programmer

The EPH A27-HW is a wired 2 zone programmer that sets separate times for central heating and hot water. It suits a system or regular boiler with a hot water cylinder and two zone valves, or a 3 port valve. We keep it In Stock at our South Street counter in Glasgow.

Each zone can run on 24 hour, 5/2 day or 7 day settings with three on and off times a day, and each has its own boost button. It fits an industry standard 6 pin back plate, so it is a common straight swap for an old two channel programmer.

Take a photo of the old wiring before you remove the old unit, and check the terminal numbers match.

See the rest of our timeswitches and programmers, or come in and see it on the counter.

Common Questions

Can I use the A27-HW on a combi boiler? A combi has no stored hot water zone, so a 1 zone timeswitch such as the EPH A17 is usually the better fit.

Does it fit an old programmer’s back plate? It uses an industry standard 6 pin back plate, which fits many older programmers. Check the terminals first.

Can I collect it today? Yes. It is In Stock at our South Street counter during opening hours.
