Electrical installation
Connection between controller and sensors
Sensor connection is diff erent according to the combination of
indoor unit and controller. Refer to the appropriate combination
mentioned below.
Use two-core cable with a minimum 0.5mm2 cross section.
Regarding other sensors not mentioned in this chapter, refer to
page 49, Optional connections.
<RC-HY20 with HSB60>
• 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.
Connect the sensor to the port 3 and 6 on X2 terminal.
If a conduit is used it must be sealed to prevent condensation
in the sensor capsule.

• Hot water charging sensor BT6 (tank bottom)
The temperature sensor, hot water charging (BT6) is placed in
the submerged tube on the water heater.
Connect the sensor to the port 5 and 6 on X2 terminal.
Hot water charging is activated in menu 5.2 or in the start
guide.

• Hot water sensor BT7 (tank top)
A temperature sensor for hot water top (BT7) can be connected
to RC-HY20 to show the water temperature at the top of the
tank (if it is possible to install a sensor at the top of the tank).
Connect the sensor to the port 4 and 6 on X2 terminal.
