## Questions & Answers

**Q: I have a basic drayton controller now. would i be able to replace it with this one myself (not very technical) or would i need to get a plumber?**
A: Drayton never made a 3 channel programmer like this until very recently, so I would guess yours isn't a 3 channel programmer.  I would recommend getting an electrician in and they can advise you on a suitable timer.

**Q: I have a hot water cylinder and the heating is provided in the ceiling (electrical), can this timer be fit and used with that configuration?**
A: The Horstman has three channels so can be used for example, for upstairs heating, downstairs heating and hot water controller. It manages the pumps out of the boiler. I am not sure that I understand what you want it to do.

**Q: Can someone explain what htg1 and htg2 refer to and how to tell the difference? we've just moved into a house with this model in it and haven't a clue**
A: In my house I have two boilers one for the upstairs and one for the ground floor. htg1 does the ground floor and htg2 does the upstairs. If you are not sure which one controls what then leave one of them off and see what goes cold...

**Q: Can this item be returned for a full refund?**
A: I believe yes

## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to replace the faulty controller
*by M***I on 19 January 2023*

Previous Horstmann controller failed after 8 and a half years. I live in a remote area and we have a lot of power cuts which probably ran down the non-servicable internal lithium battery faster than normal. Anyway, blank display despite power to the unit, & didn't respond to the factory reset procedure.Replacement is easy, just cut the power to the back plate and the new controller just pushes on and is secured by 2 captive screws. These screws weren't captive on the previous controller and were fiddly to start, a useful modification.The new controller needs a fairly strong push to get it to seat in properly, but it's an easy job as the old backing plate is fully compatible with the new controller.The Horstmann branding is changed to Signal but the model number is the same.Programming isn't very intuitive, but the booklet explains it. A video would be useful to see how to do it.The only real fault is the lack of a serviceable battery, which means built in obsolescence eventually.

### ⭐⭐⭐⭐⭐ Excellent replacement unit which is a direct swap. Very easy to fit.
*by S***H on 8 October 2021*

Needed a replacement for an 18 year old unit. This is a direct replacement and would have fitted to the old back plate if needed. Changed backplate due to it being pitted and dirty. If in doubt, suggest other purchasers get a new one before trying to remove old unit to see how it fits. It really is simple to change and would take about 30 seconds to swap if just the unit is replaced. Takes longer to switch off/on power and set up timers than replace if not changing backplate. Definately an easy diy job once you see how it fits. A really good product and good to see fitment has not changed by the manufacturer over the years.

### ⭐⭐⭐⭐⭐ Simple replacement of pre-existing unit that had failed
*by S***. on 21 January 2023*

We've had one of these installed since 2007 and it has just failed. The new replacement arrived on time and just fitted straight onto the old back plate so no rewiring required. The only negative with these units is that the back up battery can't be replaced. According to the instructions, it should last the life time of the unit but in our case the old unit outlived the battery so for last few years the unit needed reprogramming after a power cut. The old unit was extremely difficult to pull off its back plate. After removing the two retaining screws I resorted to levering it off at the top with a large screwdriver - it takes some doing. Its sold under the Horstmann name but the company rebranded themselves in 2020 - they're now called Secure.
