Solar flow sensor B63 ¦ Solar return sensor B64
Determines the temperature is measured using the temperature sensors
connected to input H1 or H3 (solar flow / or return). The controller applies the
measured temperature to control the corresponding components.
The sensor on BX has priority is the same sensor is defined for the temperature
measurement on both BX and Hx.
