Sangamo Powersaver products are a set of simple to use, multi application controllers which offer a wide choice of programming functionality & flexibility. All of the products are designed to control the timing operations of applications such as water heating to ensure expensive energy is not wasted. Heating and hot water heating account for 43% of a home’s energy usage (mapawatt.com) – the Powersaver range can reduce energy and fuel costs for these domestic applications.

Our popular range of programmers, for controlling hot water and central heating, featuring a bright back-lit display and easy to use push buttons hide an adaptable, feature-rich product. Each product can be switched between 24 hour, 5/2 day and 7 day programming rather than having separate products for each and can be programmed with either 2 or 3 on/off functions per day. The switch between Summer and Winter time is handled automatically so there’s no need to reset the clock twice a year either!
