Q: Will this timer replace the Honywell ST 1000 without having to replace the back plate and wiring?

A: Yes it will.
Q: Hi, My sister has an old boiler at present it is controlled by a horseman type Q Mk 111 electro mechanical timer...this antique has finally given up the ghost after many many years of great service. That timer controlled the CH and domestic HW......I am pretty sure the HW is a gravity fed system to the hot water tank in the bathroom airing cupboard directly above the boiler (located in the kitchen). The Q has. 5 position dial offering all the permutations to control either or, both and off etc. What would be the best horseman 24 hour seven day timer to replace this defunct unit. .....preferably one that does not need extensive rewiring. Many Thanks Ed

A: Wow that is an old one! Yes, this will do the job.
Q: I have a NLH 27 Channelplus XL. Can I use the H27 XL series 2 with the same back plate? Many thanks

A: Yes you can. It will plug on with no wiring changes for an easy swap.
Q: I have a horseman 527 is the H27 XL direct plug in replacement ?

A: Yes it is.
Q: On a 'gravity' setting, can the hot water be set at different times to central heating. I understand that when heating is on, water will also have to be on but I am not sure about the hot water running independently timed.

A: When in gravity mode, the H27XL reverts to a common timebase for heating and hot water.
