It all depends on how complicated you want to make it.

In the simplest form, all you need is a multi-stage thermostat , a couple (well, 6) contactors and a bunch of relays.

On the other end, you could fit an outstation, a bunch of relays and take full control from a BMS system.

The options are endless and the sky is the limit (well, one assumes the customer's budget also will, somewhat, limit the choices available)
