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.

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.

Asked by: niggie

Radiators-heating separate timing from tap-water heating?

E.g. does timer allow set room-heating on 7am - 8am *without* tap-water heating on? + Tap-water on 9am-9:30am *without* room-heating on? Thx from Stephen
Asked by: StephenOn3rdRock

Does not seem to work when replacing my previous controller

Purchased this item to replace Honeywell 6200C. Connections are same so wired backplate same as previous. When called to switch on heating, ch light illuminates but unit can be heard clicking (presumably on / off / on..etc) and boiler starts to fire up but then stops / starts to fire up then stops etc. Have replaced the purchased item as originally suspected faulty, but same problem with new unit. Any help greatly appreciated.

Asked by: heha

Is this suitable for controlling immersion heater economy 7?

Asked by: JackBiker
The specifications state that the contact current rating is 3A, A typical immersion heater requires a minimum of13A, therefore this programmer is most definitely NOT SUITABLE. You should use a purpose made immersion heater time-switch.
