hi everyone,
Planning to replace my son's Honeywell T40 Thermostat with Tado x wired smart thermostat and need some advice please.

Current set up is below:
Honeywell T40 Thermostat
Iflo Timer/programmer
hot water tank in loft open vent
Boiler is Glowworm Flexicom 15HX Hight efficiency condensing boiler

Question:
i dont plan to change anything with the hot water. just the heating so we can have more control on heating.
will this work with the Tado wired smart thermostat X (starter kit) and if so how do i wire it please? anything i need to be aware of please.

i have attached some pictures of current Thermostat wiring, the iflo timer as well. unfortunately there is no model number anywhere on that Iflo so no idea what model it is.
many thanks
