The Siemens RWB29Si is a weekday/weekend programmer for central heating (CH) and domestic hot water (HW). Set the same ON/OFF times for Monday to Friday and different times for Saturday and Sunday, if required.
Key Features:
– Weekday/weekend programming for central heating and hot water
– Four switching options: Auto, Manual Off, Manual On and Once (All Day)
– Advance button brings forward the next switching time
– +HRS button extends the heating in one-hour steps, up to a maximum of 3 hours
– Holiday mode: set from 1 to 99 days, then the programmer returns to your normal programme automatically
– Boiler service interval reminder, which can be enabled by the installing engineer
– Day, date and time preset, with automatic changeover for daylight saving hours
Please note: some older systems are not capable of having central heating ON when the hot water is OFF. If you are unsure whether this programmer suits your system, please contact us before ordering.
We recommend this programmer is fitted by a qualified electrician or Gas Safe Registered Engineer.
