 For that, I've "recycled" a peak/off peak 3-phase relay but you can use any 3-phase relay. It doesn't matter on which phase the command coil is connected, but it must be permanent (not through the router).

 You don't need to buy a 3-phase kit to convert your single phase heater.
 The ACI pcb must be connected to a permanent phase. It will then control any 3-phase relay.
