Does the RWB2E have the same backplate as the Potterton Mini-minder E? Is the RWB2E a programmer for both hot water and central heating? Answers1

Yes, it will fit the Miniminder E backplate.
Yes, it controls heating and hot water.

I have one of these and have set the heating to All Day. I’ve set the hot water to Twice. Is it correct that the light for the hot water stays lit even outside the parameters of its timings ie when the heating light is on? I assumed the hot water light would not be lit outside it’s programmed hours Answers1

Yes, if set to gravity mode it will automatically bring on the hot water when the heating is on. As that is a limitation of gravity systems.

Hi

A neighbour of mine has an old Glow-worm Master Mind controller, which has finally given out.
Would this be a direct replacement for it?
Thanks,

Hi

Yes it would.

I'm considering your Siemens RWB2E as a direct replacement for an existing Potterton RWB2. Please confirm that it is. Also, does the Siemens come with it's own backplate in case I find it needs replacement due to age. Many thanks Answers1

Yes, it will fit the existing RWB2 backplate. It does come with a new one if needed.

I have an RWB2E, my system won't turn off now it's ON 27/7. the lights on the controller goes on and off as per program and the clock goes around as normal. can't make out as to what is causing this issue........ regards Marc Answers1

Hi
It sounds like a stuck motorised valve.

I have a RWB29 controller controlling an oil fired range cooker on a Narrowboats. The controller screen is no longer readable, the characters are more than half missing. The controller spends long periods without a mains supply. I am thinking of changing to an RWB2E. Will this controller fit into the same backplate?
Any idea why the RWB 29 is misbehaving? Answers1

Yes, it will fit on to the existing backplate for a simple swap. It does not have a battery backup, so will need the time setting when power is restored.

Neither unit is designed to have long periods without power.

Hi! Could you confirm this programmer is the same as the image on your website as we are replacing it for a 90 year old who would like it to be exactly the same as he currently has for ease of use! Many thanks Denise Answers1

Hi Yes it is.

Hi would this replace a old crossling controls Answers1

Hi. It is a direct replacement for the Crossling Controller programmer.

Hello, I have a single pipe heating system with a Glow Worm back boiler and a Landis & Gyr RWB2 Timer and need to replace the timer. I know the RWB2E will fit as a direct replacement but has it got the facility to operate a single pipe system? My current timer has a switch on the back which physically stops the central heating slider from being turned on if the hot water is not on so the hot water has to be turned on first then the central heating, a requirement for my style of heating system. Before I order this timer unit please can you tell me if it is suitable for my needs? Thank you. Answers1

Yes, it can be set to work suitably for your system.

Will this replace a Potterton Mini minder e Answers1

Yes it will.

is this a direct replacement for the old landis & gyr rwb2 ? Will it fit onto the existing back plate ? and what does the "E" denote. many thanks. Answers1

Yes it is. It will fit on to the existing backplate for a simple swap. The E simply signifies it works internally using electronics rather than moving parts.

Good morning,I need to replace a Randall 3060 (almost 40 years faithful service!!).Is the RWB2E or any other programmer you sell suitable.Not a digital one though. Thank you. Answers1

Hi Yes, it will be suitable. The RWB2E comes with a wiring conversion guide for the 3060 to help you with the swap.

Does this timer easily replace the Potterton Miniminder or do we need extra wiring on the backplate or to change anything on the heater? Answers1

It's a very simple DIY swap. No wiring changes needed.

Hi, I have a Microgyr 40 heating control that’s not working, will this product be a easy replacement. Other product that you recommend. Rgds R Wells Answers1

Yes it will. It will plug onto the existing backplate for an easy swap. Also see the Siemens RWB29Si as an alternative.

Is the RWB2E programmer a direct replacement for the RWB9 programmer. Is any re-wiring of the backplate required? Answers1

Yes it is. No wiring changes needed.
