Recommended External Device
Specification
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 fixed at a suitable location to
more accurately measure ambient
temperature.
4 Room
sensor:
PAW-A2W-TSRT
Install the room temperature sensor to the
room which requires room temperature
control.
5 Solar sensor: PAW-A2W-TSSO
Use for measurement of the solar panel
temperature.
Insert the sensor into the sensor pocket and
paste it on the solar panel surface.
