Timers &Controls ●From previous page
Using the free Sangamo Connect app on an Android NFC enabled smartphone allows you to upload a created programming schedule; download an existing schedule to store or amend, as well as transfer programmes from one switch to another.
The range also includes Astro Switches also
known as solar switches, which automatically adjust their on and off times to match sunset and sunrise times, and a selection of Standard Switches, generally used to control heating, ventilation and door entry systems, completes the range.
Programmers Programmers are a key component of heating control systems. Since many homes are unoccupied for parts of the day, there is little point in heating them if no one is there to benefit. A programmer allows the occupant to specify when the heating comes on to match their lifestyle and heating requirements. Sangamo’s Choice range of programmers for timed heating and hot water control offer adaptable programming options with a modern design to suit any home. Each model can be toggled between 24 hour, 5/2 day or 7 day programming, 3-in-1 options.
The single channel Choice model is designed
primarily for timed, simultaneous control of heating and hot water. It is ideal for use with a combination, or combi boiler, and it has a Volt Free Contact. The 2-channel Choice is designed for separate control of heating and stored hot water, the programs are independent of one
another, giving the opportunity to control usage in the most energy efficient manner possible.
Thermostats A room thermostat is used to regulate and maintain a desirable temperature throughout the home. It works by switching the heating system on and off as the temperature varies throughout the day. If the temperature drops below a certain level, a sensor in the room thermostat can be made to trigger the switch for the boiler and
pump which will heat the radiators. If the room rises above a certain temperature, the thermostat will then turn off the central heating system so that your house will cool to its desired temperature once more. Sangamo’s Choice Thermostats comprise mechanical, tamperproof mechanical, digital, wireless digital and wireless digital programmable versions. The Smart Thermostat with APP is an intelligent system, which predicts the start of the heating period to ensure comfort. Widely compatible, it can replace most wired and wireless thermostats on the market, and be used with fuel, gas and wood systems.
Powersaver Controllers The primary application for the Powersaver range is to control immersion heaters. In a typical UK household, nearly 20% of a home’s energy cost is spent on heating hot water. Leaving an immersion heater on all the time can be a significant waste of energy that can drive this figure up to 25% or higher. Fitting a Sangamo immersion heater controller can reduce these costs by up to 50%, even more if the property can take advantage of dual tariff electricity and controlled by the Powersaver Dual Flexi. The Powersaver Boost and Select models are rated at 16 amps and can be used for other applications such as controlling panel heaters in both domestic and commercial properties, switching towel rails and more.
We regularly hear from people with Round Pattern Time Switches still going strong aſter 50
years. When they need a new switch they assume, because of its age, that it might not be possible to get a like for like replacement. However, an RPTS bought today is completely interchangeable with one bought decades ago.

Beat the winter blues We are now in the coldest months of the year, when any inadequate or inefficient heating control systems will be taking a toll on the comfort and energy savings of households across the country. But, it’s also the perfect time for wholesalers to advise their installer customers about the best upgrade products and solutions that they can be recommending to their clients.
