Hi Everyone.
I have just moved into a not-so-new house and have noticed that the combi boiler has no in-built time time switch. It actually has a seperate thermostat time switch made by Drayton Tempus One. I have had to replace this time switch as the digital display does not work. I replaced it with the up-to-date Tempus One unit and connected it with the same wiring as had been previously done. However when operating the switch on a program it does not switch on or off the thermostat. Instead it is permanently on or off, depending on how high the thermostat has been set.
My wiring takes in a feed from the mains switch into the Tempus One unit, and also the 3 cables (L/E/N) to the thermostat switch. As follows:
From Mains into unit: Live to L, Neutral to N, Earth to earth
There is a standalone loop from L to 1 for the Live cable.
From Thermostat into unit: Live to 1, Neutral to N, Earth to 1.

If you visit, and then select the Instructions for the Tempus One it will show you on page 4 the wiring diagram for how the unit should be set up.

Any suggestions as to why the switch in the unit does not work would be very helpful.
Thanks.
