Everything working well until I removed existing Honeywell rotary room thermostat and Installed digital Heatmiser programmable room thermostat.
Existing wiring is 3-core mains supply to manual rotary timer. From rotary timer there is 5 core wiring leading to Boiler. And from rotary timer, there is 3-core cable to room thermostat. (I would assume that 3-core to room thermo is live, neutral and switched live.)
Upon completion there is no power at new programmable thermostat.
I have tried combination of different wiring at room thermo but nothing. Any help would be greatly appreciated.
