Q: My Landis & Gyr RWB2 is broken ( the slide control lever for the central heating no longer moves) and I need to replace it with a Siemens RWB2e. Is the backplate the same so I can inset the pins into the relevant slots or do I need to get an electrician to rewire?

A: Yes, it is exactly the same. So it is an easy DIY fit.
Q: Can extra pegs be inserted to the timer dial on my RWB2 to increase the number of timed periods?

A: I'm afraid not.
Q: I have an RWB2E.cw controller by Wickes. Can I purchase and swap this controller for the RWB2E controller. Any idea what the cw means at the end

A: Yes you can. The CW just signifies it was sold by Wickes.
Q: I received this today and installed it as a replacement for the RWB9, on the same baseplate, on a pumped heat and gravity hot water system. I appreciate that this means that I cannot run the heating without the hot water. The time clock works fine, there doesn't seem to be an interlock between the heat and hot water controls, so hitting the heating boost button brings in the pump but not the boiler. Likewise I can set it to heat 'all day' and water twice, and the boiler cuts out after the first timed period (when the heating should still be on). I got it to simplify the controlling for my wife who did not understand the digital one, but if I need to explain that to boost the heat she needs t hit the hot water boost button as well she'll be really foxed. I seem to recall that on my original randall analogue timer there was a mechanical interlock that prevented you from setting the heating for more time than the hot water. What's the answer please?

A: To convert it to gravity mode please do the following: 1. Selector sliders must be in the following position: HW - OFF CH - OFF 2. Insert a small, flat bladed screwdriver into the square opening, on the rear of the programmer, with the flat end horizontal, then push fully up to the top of the slot opening. 3. Also move the switch on the rear of the programmer from 10 to 16 position, i.e. from left to right.
Q: i bought one but lost the manual and didn't know how to adjust . tell me how to use a RWB2E Siemens (Lindais & Staefa) central hearing programmer

A: Please see the downloads tab.
Q: Are the screws for fixing the back plate on the bottom or on top?

A: They are on the bottom.
Q: The clock timer doesn't work, will I have to replace the whole RWB2E please?

A: I'm afraid so.
Q: Is iy possible to have the CH on without the hot water?

A: As long as you have one or more motorised valves on your system
Q: Hi, sorry if this is a thick question but with this programmer, can I have just the hot water on without having the CH on? Also, do you deliver to Southern Ireland and what s delivery cost please? Many thanks.

A: Yes, you just set the Heating slider to the off position. Yes, we deliver to Southern Ireland. The cost is £10+VAT.
Q: Can I do a straight swap of my broken RWB1 with a RWB2E Programmer? Are the connections compatible?

A: Yes it will plug onto the existing backplate for an easy 5-minute swap with no wiring required.
Q: O have moved into a house with this programmer, it seems to work fine but I am unable to move the start and stop orange and blue buttons. Please give me instructions

A: To set tappets to your own programme times hold the dial and slide the relevant tappet and rotate it in either direction to your desired time, then rotate dial through a full 24 hour rotation. NB: This should be carried out with the Programmer connected and power supply switched onto the backplate.
Q: What is the difference between the override button and the boost button on this programmer?

A: The boost will turn its self off after an hour.
Q: I have a RWB2E system which has worked fine for years but for some reason when I now move the switch for the heating to come on twice in the day the system does not now work. Is there a way which the system can be reset or do you have any suggestions on how I can get this fixed??? Thanks

A: If it's working on once and overrides, then it sounds like the system is fine and just the programmer needs to be replaced.
Q: I'm staying in a VRBO unit in London that uses this timer for heat and hot water. While trying to turn on the heat tonight, my daughter turned the timer first clockwise and then counter-counterwise. A ticking sound ensued. I turned the heat and hot water off, and the ticking stopped. Turned the heat back on. Ticking still gone. Turned the hot water on, and the ticking was back. Have we busted the timer??

A: If its got power and not turning, then it sounds bust.
Q: I have a 30 year old Landis & Gyr RWB2. Will the Siemens RWB2E be a suitable straight replacement or is there another option ?

A: Yes, it will plug onto the existing backplate for a simple swap.
Q: Is this interchangeable with a busted Horstmann 425 Tiara?

A: You will need to change the backplate.
Q: I currently have a Siemens RWB29. Can I replace it with a RWB2E to the existing backplate?

A: Yes you can.
Q: My rwb2e Siemens controller is stuck in the on position and clock not moving round. I have ordered a new programmer from you - will it be easy to swap them over? Some of your answers to other questions say you can use the existing backplate - is this the same in this instance?

A: Yes you simply: 1) Switch off the electric 2) Remove the old timer from the backplate 3) Fit the new timer onto the backplate 4) Switch on the electric. A very simple 5-minute job.
Q: I have a Landis and Gyr Type RWB 4 controller fitted to a Glow-worm 85-100 boiler - will this unit replace the RWB 4 or do you have an equivalent replacement available please?

A: You will need to install the RWB2E on the wall next to the boiler and link it into the back of the RWB4. There is nothing that will go onto the existing backplate.
Q: When replacing onto existing back plate, do we have to switch the power mains off before setting the RWB2E timer?

A: Yes, you will need the switch off the power before removing or fitting the programmer from/to the backplate.
Q: Will this unit replace a 35 year old Crossling control unit

A: It will replace a Crossling Controller. Please contact us for other models.
Q: I have a Potterton mini minder Will the RWB2E be a straight swap or do I need to change the back plate ?

A: It is a straight swap, you will not need to change the backplate.
Q: Can it be thermostatically controlled

A: You can install thermostats to use with it, like the RAA20 room thermostat.
Q: Replacing RWB9 with a RWB2E, Backplate&Wiring compatable ,no alteration required,is this correct thank you.

A: Yes it is.
Q: hi have a landis rwb2 do you sell a digital programmer that will just fit over existing back plate..

A: Yes, the RWB29 will fit onto the existing backplate: http://www.heatingcontrolsonline.co.uk/siemens-landis-staefa-rwb29-programmer-p-43.html
Q: I have a mini minder E programmer will the RWB2E replace without changing back plate and wiring and how do I remove the old programmer from back plate as there are no screws do I have to tweak a plastic lug on backplate with screwdriver? thank you

A: Yes it will. There will be 2 screws on the underside of the unit. You will need to loosen them - and the programmer will hinge up and off. If your programmer is tiled in, the screws may be covered.
Q: HI, I have an old landis n gyr RWB200 programmer for CHeating + gravity HWater. Will the RWB2E be a suitable replacement and will it fit the present Backplate. Thanks in anticipation. Pete

A: Yes, it will simply plug onto your existing backplate for a simple swap. If you would prefer to keep to a digital programmer, then you will need the RWB29 or RWB2001.
Q: My rwb2e Siemens controller is stuck in on position and clock not moving round. Does whole unit need to be replaced or is there something I can do to remedy .

A: You will need to change the whole programmer.
Q: Is this an easy replacement for a Landis & Gyr RW2? Will it simply fit over my existing wall plate with no wiring changes necessary?

A: Yes, it will. It's a very simple 5-minute job.
Q: This replaces the RWB2 I take it? Also can I have hot water on only because at present with my RWB2 the hot water and radiators are on and this is not cost effective.

A: Yes it does. It has just one set of timings for heating and hot water. for different times, I would recommend the RWB29 instead. Please see the link below. http://www.heatingcontrolsonline.co.uk/siemens-landis-staefa-rwb29-programmer-p-43.html
Q: Does this RWB2E replace a (faulty) RWB9?

A: Yes it does.
Q: Can this be switched on/off at customers discretion ?

A: Yes, The heating or hot water can be switched off by moving the appropriate slider into the "Off" position.
Q: can the controller be set to come on once a day only (not twice)?

A: Yes it can, Move the slider to the once position.
Q: when the programme says 'all day' what time does it go on and off at?

A: It switches on at the 1st on tappet, and off at the last off tappet. The two middle tappets are ignored.

Very pleased quick response and delivery
I ordered four TRV's and required a next day delivery, which I paid for and had qualified to get. They should have been delivered before 6.30pm next day. I had hoped not to be the last delivery of the day but waited patiently. The tracking system said it was on board, so I waited at the job hoping it was just late. It did not turn up till the day after that and It was only luck that someone was in to receive them. I reported the incident to you and was told I would be refunded "the difference" (Which has not happened yet). I am disgusted that I paid for a delivery service that I did not get I.E. "Next day service" and have to pay at all for it. To be offered "The difference" is an insult and unjust. Don't advertise "Next day service" if you can't deliver it. I appreciate this is contracted out. I hope they are suitably dealt with, but as it is you who has been paid, you get the complaint. The products (TRV's) are fine and I have no complaint with them at all. Shame about the delivery service.
Great service, fast delivery (to Ireland!) and keen prices.
