Electrical installation
<RC-HY40 with HSB100>
• Ambient air temperature sensor BT1
Install ambient air temperature sensor (BT1) in the shade on a
wall facing north or north-west, so it is unaffected by the
morning sun for example.
Connect the sensor to the port 1 and 2 on X6 terminal on AA3
board.
If a conduit is used it must be sealed to prevent condensation
in the sensor capsule.
