No. Only the controller and key are supplied. Sensors (outdoor ESMT, immersion ESMU) are ordered separately — they are often already present after the initial installation.
Typically A230 or an equivalent single-heating + DHW key. Confirm the actual revision with us before ordering — Danfoss has revised article numbers over the years.
No. A2xx keys work only in ECL 210. ECL 310 requires A3xx keys.
