Landis Staefa Heating Programmer - replacement

holidayinn

Hi all,

I have the Landis Staefa heating programmer (pictured GYR but essentially the same) in my new home. I want to upgrade this to a newer, more user friendly version. It looks a lot like the RWB2e but slightly different layout.

Could anyone please help me with what would be a suitable replacement, ideally I could install myself?

Anyone know where I can find this info out other than asking on similar forums?

Thanks,

Do you want a like-for-like replacement or would you replace the rooom thermostat too and have a programmable thermostat?

These devices are essentially just switches (one for heating, one for hot water) that flick on and off according to the times set. If you also have a room thermostat, it is also a switch placed in series with the heating programmer - so if the heating programmer is on, AND the thermostat is on (i.e. the room temperature is less than the temperature on the dial), the boiler will receive a signal to heat up. It's really quite simple.

A better approach is to put the thermostat and the timer in the same device, so you only have one switch. In that case you can program it so that at different times of the day the thermostat is automatically set to different temperatures - e.g. you can have the heating on low during the night in case it gets very cold, then have it much warmer in the morning when you get up.

You could put in one of the high-tech smart thermostats like Nest.

You could put in something like this - however the thermostat is integral to the device so it would need to be positioned in a suitable place for a thermostat.

If positioning is an issue, you could get a wireless controller. But there don't seem to be so many wireless dual-channel controllers on the market, for some reason (dual channel being for both heating and hot water).

Or you could stick with the controller you've got to control hot water and get a single channel programmable thermostat just for the heating.

The wiring layout of the landis timer will have the same wiring layout, you will probably have to swap the back plate over but wiring should be the same.

L-N-E
3 - HW On
1 - HW Off
4 - CH On
2 - CH Off

The Drayton clock follow the same pattern, I wouldn't tie my self to 1 brand, the wiring will be pretty straight forward on which ever one you pick, with wiring diagrams in the paperwork and the current wiring diagram will be on the back of the current timer.

Thanks Alex and Benjus,

Will research the info you've provided and probably return with more questions at some point!!
