Direct replacement but battery can be replaced
Bought as a direct replacement for a Horstmann controller whose built in battery had gone flat. Every time there was a power cut, the battery no longer held the times I had set so I had to manually re-set them, a tedious process. The battery is designed not to be replaced as it is fixed on the circuit board. Having fitted the new timer, I stripped down the old one and I believe that I could replace the battery (a CR2430) on the circuit board (cost less than £2) rather than having to buy a new control timer for nearly £70. The new timer works perfectly well, but I know I will be facing the flat battery issue again in 7 years or so.Verified purchase: YesCondition: New

A reasonably good controller, easy to fit and programme. The battery should last five years, but runs down quicker if the m
I got this as a replacement for an identical controller, due to the battery having run out on the previous unit. As it was a like-for-like replacement, you only need to replace the front part which contains all the electronics, which simply slots into where the original detached. This means you don't have to disconnect and reconnect any of the wires coming into the back part, which is really only a terminal board. The programmer is relatively easy, if a bit laborious, to programme. You can set the times to within 10 minutes for the heating and or hot water, for three periods each day of the week. You can have these times different for each day, or can have them the same each day, which is a bit easier and takes less time to set up. Also useful are the Boost override buttons which allows you to bring on the heating and / or hot water for 1 or 2 hours at any time. One thing to watch is if you turn off the mains electric switch on the wall, say over the summer, the controller's battery is used more keeping its time setting, and eventually shortens the life of the battery. Ours lasted 4 years, switching the system off at the wall in the summer months. If the battery has run out, when you restore the mains electric supply, the unit will work, but you have to re-programme the time, and each heating and hot water settings. This works fine until there is a break in the power e.g. power cut, when the controller loses the time and all your settings. The battery is non-replaceable, meaning you have to buy a replacement controller, like we have had to do. The expected life is stated as 5 years by the manufacturer. I'm not sure how you get round this without leaving the mains power on all the time.Verified purchase: YesCondition: New

Does what its supposed to
Once the unit is put together it is extremely difficult to prise apart, so don't clip together until in its final place on the wall and the wiring has been completed, it is possible to part clip it in place to check everything is working prior to final installation, but overall very pleased with my purchase, good instructions with alternative wiring for replacing your present unit.Verified purchase: YesCondition: New
