AUX inputs
Up to 6 other external inputs are available on RC-HY40.
AUX1 through 3 correspond to the port 9/10, 11/12, 13/14
respectively on X6 terminal on AA3 board. AUX4 through 6
correspond to the port 1, 2 and 3 on X2 terminal on RC-HY40.
Port 4 on X2 terminal is GND and is common to AUX4
through 6. Connect a sensor or switch between AUX and GND
with a two-core cable with a minimum cross section of
0.5mm

Temperature sensor BT63 is applied in case additional heater
is placed before 3-way valve (see page 23 for diagram)
The following functions are available. For details, see AUX
inputs for RC-HY20.

Room sensor BT50
Refer to Room sensor BT50 for RC-HY20 for function and
installation place.
Connect the room sensor to terminal block X6:3 and X6:4 on
the input board (AA3).
If the sensor is to be used to change the room temperature in
°C and/or to change/stabilise the room temperature, the sensor
must be activated in menu 1.9.4.
If the room sensor is used in a room with underfl oor heating, it
should only have an indicatory function, not control of the
room temperature.

CAUTION
Changes of temperature in accommodation
take time. For example, short time periods in
combination with underfloor heating will not
give a noticeable difference in room temperature.
• Step controlled additional heat
Refer to the explanation for RC-HY20.
• Relay output for emergency mode
Refer to the explanation for RC-HY20.
• External circulation pump
