Rated 4 out of 5 by from Good timer Straight swop for 15 year old timer. Plugged in no problems. Instructions for use looked complicated. I was wrong worked through them with no problems and its great that I wont have to change to summer time. Here's to another 15 years so we will wait for reliability to have more stars.

Asked by: blisser

Is this suitable for controlling immersion heater economy 7?

Asked by: JackBiker
No. This type of programmer is designed for switching a small load such as a boiler, circulating pump or zone valves with a maximum load of 3 Amps. A standard 3Kw Immersion heater would require a switching capability in excess of 13 Amps. A suitable timer would be the LAP 7-Day digital immersion timer, also available from Screwfix.

Asked by: heha

Will this be a direct replacement to a Landis & GYR RWB2 programmer if not can you recommend another 1

I want to upgrade my old mechanical timer that controls HW and Heating. It has 5 wires but I am confused as to my options. Can I only replace with a 5 wire or can I use a 4 wire unit. My system is gravity fed but i do have a shower pump, if that makes any difference.
