Yes. The iQ WiFi element’s radiator mode, which controls the internal temperature, can be used as an LST function.
On this mode, the internal sensor measures the temperature of the heating medium where it passes the element. The set temperature range is 30-70 °C and can be adjusted in steps of 5 °C. A setting of 30-40 °C would keep any radiator using the element below the 43 °C limit required by the NHS for LST settings. See attached for a guide to setting radiator mode from the control head.
