Replacement Room Thermostat - Manual to Programmable Digital

[TomBradbury]

Currently have an acl Drayton RTS 1 room thermostat, but want to replace with a programmable (5/2) digital thermostat so I can change heating requirements throughout the day and night. Been browsing loads of sites but can't find one to replace. Taking off the current thermostat and the wiring is on the backplate is Live, Neutral, Earth and the call cable is yellow.

Any suggestions/recommendations? Don't want wireless.
