I have installed a V3+ starter kit to replace a Danfoss TS710 and a RET2001 connected to a Ideal logic combi esp1, all Tado equipment connected and talking to each other but when the heating is switched on there is no action from the boiler. Hot water working fine just no CH when demand from the Tado, anyone got any ideas what could be wrong

    Probably the wiring.

    When you removed the TS710, what did you do with the wiring?

    • If the TS710 has been removed and the wiring is still sitting there unchanged, it is probable that the wiring centre is waiting for the connection from the COM port, to the NO port to be bridged.
    • If you removed the wiring that went to the TS710, did you make sure that within the the wiring centre, a bridge was inserted between the cable that fed the COM port and the cable that received the signal from the NO port on the TS710.

    What kind of Tado kit did you fit? Was it a wired thermostat, fitted to where the RET2001 was fitted, or was something else done?

    • If it was fitted to where the RET2001 was fitted, do you have something to test the voltage from the wires going to and from the Wired Thermostat?
    • A simple electrical voltage testing screwdriver to check what happens at the wiring centre, which is probably close to the boiler. Do you feel comfortable handling that?

    If you don't have a tester, or don't feel comfortable, best to have an electrician get involved.
