Q: I have a Landis & Staefa RWB2E Mechanical Clock that now sticks whenever it feels like it. Normally in the morning before it is supposed to switch on! Is the RWB29 a suitable replacement and easy to wire up again.
A: Yes, you will not need to do any wiring, the RWB29 will clip on the existing backplate for an easy 5-minute swap.
Q: Could you please confirm that this unit RWB29 is the one with a "battery backup" and comes with a replaceable battery, with an accessible battery compartment in the back of the unit? Many thanks
A: It has a battery backup. However, due to EU laws, changing the battery is now a "specialist" procedure that should only should be carried out by a professional. Siemens instructions reflect this and they have placed a sticker over the battery drawer to stop the user changing it.
Q: I have a L&G RWB2. When the CH is 'on' the room thermostat switches the boiler on and off as needed according to the set program. However the HW can either be on or off and the on twice or once does not function as the clock does not rotate. Assuming that the clock is faulty and I replace it with you programmer, will this resolve the problem? Will my thermostat continue to work for the CH?
A: If the clock is not rotating, then it is faulty and needs to be replaced. This is the suitable replacement. It will work with your existing room thermostat.
Q: Hi, my central heating has started to run constantly even when the thermostat in set to low, and the RWB29 timer is showing both hot water and heating off. I am manually turning the boiler off to stop this, but my plumber thinks it might be a fault with the timer. Is it worth replacing the timer, or is my plumber barking up the wrong tree!
Many thanks for any ideas.
A: If it is doing it when the thermostat is low, then it sounds more like a motorised valve fault.
