Horstmann is Secure - Brand change in the UK

From 1 November 2020, all our control products in the UK will be sold under Secure brand name.

Do you have a control that has 3 or 4 channels to comply with Part L regulations?

Yes – Our H3747 is suitable for up to 4 channels of heating or stored hot water.

I have a smart programmer (C1727 or H3747) and I’m currently using Bluetooth, but I want to control my system remotely, what do I need?

Simply plug in the extra Wi-Fi card (part number SCW100-000) into the slot on the front of your programmer when the power is off, then use the same app to connect to your home Wi-Fi.

Can I add extra thermostats to smart programmer multi-zone?

The C1727 and H3747 are modular and expandable; you can add extra programmable thermostatic displays (PTDs) or temperature sensors (THS) to increase their functionality.

Do you do a 2-zone wireless controller?

Yes – Our C1727 is suitable for up to 2 channels and works either with a mobile app through Bluetooth, or is expandable with an additional  Wi-Fi card (part number SCW100-000)

Are any of your controls Wi-Fi enabled?

Yes – Our C1727 and H3747 smart programmers are Wi-Fi enabled when a Wi-Fi adaptor is installed.

Do you have any controls which have a hypothermia setting?

Yes – Our PRT1 has a built-in hypothermia setting which prevents temperatures from being set below 15 °C, and once programmes are set temperature can only be adjusted by 2 degrees up or down.

Are any of your controls suitable for those with sight impairment?

Yes – ThermoPlus range has audible and tactile feedback; our new smart controllers will have voice activation via Wi-Fi connection and can be controlled using virtual assistants.

Do you have controls with tamperproof capability?

Yes. The HTT4 or the C-Stat range of programmable thermostats can be locked.

How to convert C-Stat to manual mode and tamperproof code?

Are your controls boiler plus compliant?

When combined with the relevant thermostats our time switches and programmers will comply with Boiler plus and Part L. The C-Stat and smart programmer ranges also comply.

What happens to my programmed times when the clocks change in summer and winter?

Most Secure controls will automatically adjust to summer and winter time, meaning you don’t have to worry.

Where can we find Service plus (S17-S27) engineer’s installation codes?

How many programmes are there in the off-peak settings on the electronic 7 controller?

Up to three off peak programmes as well as a boost program.

I have an electric system and a hot water tank, but do not have Economy 7 off-peak hours.

The Electronic 7 is user programmable and works with a variety of electric tariffs.

Is it possible to set and lock the off-peak programme for my immersion heater?

You can programme the Electronic 7 then lock the unit afterwards, allowing boost only on demand.

Do I have to control CH and HW with a 2-channel, or can I use it to control two heating zones?

The channel Plus H27XL or smart programmer C1727 can control two heating zones, or heating and hot water.

Are the products different, since now you are called Secure and not Horstmann?

The products are the same quality and design, made the same way and are exactly the same apart from the name.  Still reliable, well-made and backed by many years of engineering excellence.

Do your controllers save the settings if I have a power cut?

All of our digital controllers have a backup battery or non-volatile memory and will save the stored settings, ready to resume when power returns.

What controllers do you have that I can use with my phone?

We have C1727, H3747 and Beanbag. Please see our products section for more details.
