Recommended External Device Specifi cation
•
This section explains about the external devices (optional)
recommended by Panasonic. Please always ensure to use the
correct external device during system installation.
•
For optional sensor.
1. Buffer tank sensor: PAW-A2W-TSBU
Use for measurement of the buffer tank temperature.
Insert the sensor into the sensor pocket and paste it on the
buffer tank surface.

2. Zone water sensor: PAW-A2W- TSHC
Use to detect the water temperature of the control zone.
Mount it on the water piping by using the stainless steel metal
strap and contact paste (both are included).

3. Outdoor sensor: PAW-A2W-TSOD
If the installation location of the outdoor unit is exposed to direct
sunlight, the outdoor air temperature sensor will be unable to
measure the actual outdoor ambient temperature correctly.
In this case, optional outdoor temperature sensor can be fi xed at a
suitable location to more accurately measure ambient temperature.
