Rated 5 out of 5 by from Highly recommend I bought an LP522 earlier verson 10 years ago and it has worked reliably ever since, but like all things finally needed replacing this week. Next day delivery, fitted in 5 minutes to the existing back plate and 5 minutes to change the standard programming. Pretty good and I see the mk4 now has a boost and holiday setting. Pretty good yeah!

Rated 5 out of 5 by from Straight swap. I had to replace my old Sunvic controller quickly. This pushed straight into the same backplate and was working within 2 minutes. It has 3 On/Off times, a backlight and even a holiday mode. Absolutely brilliant for the price!

Is lp522 a replacment for Randall 102 with same baseplate

Asked by: Joninstoke
The Randall 102 has a different backplate to the LP 522. The 2 plates are physically different in size. The Randall back plate will need to be removed and the LP backplate used. There are some differences in the wiring also and if in any doubt as to how the wiring should be then a qualified electrical person should be consulted.

I need to replace a potterton EP3002 with either the LP 522 or LP 722, will either of these fit the original backplate /wiring ?.

Asked by: retired98
The LP522 or the LP722 will replace the EP 3002. There will be some wiring alterations as the EPbackplate has links on it that are not required with the LP unit

Would this unit replace an old red and blue button unit

Hi, would this heating controller be suitable to replace an old Danfoss unit and is it within the scope of a DIYer
Asked by: jem1961
Before we can answer this we would need to know what the Danfoss model was.

Can i replace a Drayton Tempus 7 with this unit.

Asked by: jillyian
If the Drayton Tempus 7 has a slider at the bottom of it then the LP522 can be used as a direct replacement. It will fit onto the existing back plate without the need for any wiring. If the Drayton Tempus 7 has buttons only then the back plate will need to be changed

Would this be a straight replacement for a Switchmaster 400 utilising the existing backplate and wiring ?

Asked by: ElTee
The LP 522 would be a functional replacement for the Switchmaster 400. However, the existing back-plate will require changing and there are some alterations to the existing wiring. The wires in terminals 1 and 4 on the existing back-plate will need to be reversed. Whatever colour wire you have in terminal 1 on the existing back-plate will need to be connected to terminal 4 on the LP back-plate. whatever colour you have in terminal 4 on the existing back-plate will need to be connected to terminal 1 on the LP back-plate. All other terminations remain the same.

Replacing a SWITCHMASTER 805?

Asked by: sioban
The LP522 can replace the Switchmaster 805.There will be some wiring changes on the backplate as these are not directly compatible. No extra wires are needed just a re-configuration of the existing wires.

replacing old

Would this fit straight onto a RWB2E fitting?
Asked by: Bryony34
The RWB2E looks like it has a standard industry backplate. The LP 522 should fit directly onto the existing backplate.
