Q: I have an RWB2E timer will the RWB29 be a direct replacement without changing any of the wires in the main control box ?

A: Yes it will.
Q: I have a RWB9 unit, is there a programmer available which can use the same back plate?

A: Yes, this RWB29 will clip onto the existing backplate.
Q: Can I use the Central heating when the Hot water is off?

A: Only if you have one or more motorised valves. If you don't have any motorised valves it will bring on the hot water when you heating comes on as this is a limitation of the system.
Q: I have an HCC oil boiler with Landis & Gyr RVP75.230/151 control unit will the seimens RWB29 programmer be a suitable replacement? Boiler supplier two zones of wet underfloor heating, hot water and towel rails

A: I'm afraid not, the RVP75.230/151 is a much more complicated unit with compensating sensors. If you email sales@heatingcontrolsonline.com they will give you a price for a suitable replacement.
Q: Hi we currently have a Potterton min minder RWB2 programmer (well over 30 years old) the boiler is a Rayburn gas ranger and the system is gravity fed, I see that the RWB29 will replace this? What is 'Holiday' programming and also what is the minimum period per day the heating could be on with the RWB29?, with the potterton is about 4 hours. regards K.W.Stevens

A: Yes, the RWB29 will be suitable. The holiday program keeps the heating and hot water off, until the day you return when it will automatically return to its programmed settings. You can have a on time as short as 10 minutes.
