Hi All,

Please see image below, how can I wire up a hive v4 wireless heating and hot water smart thermostat from a old flash immermat timer for oil boiler for house heating and hot water?

I don’t think that will work, as: 1, it’s an immersion heater timer and 2, not suitably amp rated

Hi CountryFan,

Thank you for your response, Would you have any idea of the what could work?

Would you have any idea of the what could work?

Are you planning to just replace that timer? If so, with what, eg what are your requirements? Did you want heating and hot water control but maybe looking at the wrong device?

Just to replace the time, to be able to control the heating from the app that's all. Everything to keep working as it is. I probably got the wrong device.

Just to heat the house. We also get hot water whenever we heat the house from it.

Ok, maybe look at a smart immersion switch then. Unless you use anything else, eg motorised valve(s).

Sorry my mistake, It's for central heating. It's a oil boiler timer for central heating to heat all the radiators in the house. Once it's switched on we also get hot water from all the taps.

The immersion has a separate timer in the hot press, which we don't use. As we normal heat the water with the oil boiler. In the summer we close of all the radiators with one red lever in the hot press, which then heat up just water to give us hot water for shower.
