Q: Hi , is a diagram provided to show how it would clip into the back plat .

A: Hi. A diagram is not included, but it is quite self explanatory when you see it.
Q: How easy is it to replace a C11 with the C17? I have a C11 that seems to have stopped working. The LED display is there but no LED light to show heating is on. Is the replacement a non-electrician could do (after I turn off the power!)

A: Yes it is a very simple job. It just plugs onto the existing backplate.
Q: Would the back plate of a 425 Coronet fit a Centaurplus c17 timer??

A: I'm afraid not.
Q: Hi I want to replace my Sunvic TLM2253 dial with a digital unit for a combi boiler. The live and earth are connected to the Sunvic but the neutral is not (and is sheathed inside it). WOuld this be suitable, and if not what would be? Thanks

A: This is a timer, so would not be suitable. I would recommend the HRT4-B.
Q: How can I permantly turn off my heating, its programmed for off but stays on

A: You will need to find what is holding it on. It would be a faulty timeswitch, frost thermostat or motorised valve.
Q: Hi - can you use this time switch to control an electric towel rail? Thanks

A: As long as it is under 690 watts
Q: Hi, I recently moved to an apartment and have an electric boiler. There is a CentaurC17 time switch. Does this control when my hot water comes on because I have programmed in different times. Is there a way to set water temp on this c17. Kind Regards Peter

A: No, the C17 doesn't have separate hot water control. Depending on your boiler, the hot water may work 'on demand', at the central heating times, or there may be a separate control for it.
Q: Would this timer be appropriate for an immersion tank running on economy 7?

A: No, I'm afraid not. You will need something from the Immersion Heater Controls category.
Q: what load can this timeclock take

A: It can take up to 3 amp resistive, 1 amp inductive.
