The DS-SB features a set back function, a function that will automatically reduce the set temperature by 4C when no time clock signal is detected. The DS-SB thermostat has been designed to work in conjunction with our UH3 wiring centre and TM4 Programmer, but could equally be used as a standalone dial thermostat. Please note this thermostat is flush mounting, so a back box is required prior to installation. Functions include: • Slide switch mode select (Constant, Off, Time Clock) • Flush Mount * 4 core cabling is required from the time clock in order to use the set back function.
