Q: How do I set 3 on/of's per day?

A: You need to change the DIP switch on the back of the unit to the 3 on/off position. Then press the reset button on the front.
Q: I have a Potterton Mini Minder E, is this contoller a straight forward like for like swapover.

A: Yes it is.
Q: Hi, i have a L&G RWB20 Microgyr, will this be a straight swap? ive also been told the horstmann centaurplus C27 will work, can you recommend one or the other, what ever is easier to replace? Thanks Jon

A: The problem with replacing the RWB20 is that all modern programmers are mains powered so need a neutral supply on the 'N' terminal. Check if there if there is neutral connection on the 'N' terminal. If there is, then the RWB29 will simply plug on. If not, you will need to get one added.
Q: I have a very old Potterton Miniminder. Is this programmer compatible and is it just a straightforward swap? Thanks

A: Yes it will plug onto the existing backplate for an easy swap.
Q: I have a Landis & Gyr RWB200, is the Siemens (Landis & Staefa) RWB29 Programmer a suitable replacement? is it plug and play or do i need a electrician to rewire?

A: Yes, the RWB29 will plug onto the existing backplate for an easy 5 minute swap.
