Stiebel Eltron WPM 3/3i (SG Ready)

← Heating

SG Ready control via Modbus with the ISG only works in domestic hot water (DHW) mode and in automatic/programmed mode. In comfort mode, SG Ready commands are ignored. The WPM 3/3i does not provide power consumption via Modbus. Without an additional meter, power is estimated from the charge current.

Supported features

Dimmable: Power consumption can be reduced (e.g. § 14a EnWG). See External Limit.
