The Panasonic PAW-TS2 is the genuine DHW tank temperature sensor for the Aquarea range, fitted with a 20 metre cable to reach longer runs between the cylinder and the indoor hydromodule. It's supplied as standard with every genuine Panasonic hot water cylinder — this standalone listing is for pairing an Aquarea heat pump with a third-party DHW tank, where the sensor needs to be sourced and fitted separately.

Factory-fitted on genuine Panasonic tanks
If you're pairing your Aquarea heat pump with a genuine Panasonic stainless steel or enamelled cylinder, a tank sensor is already factory-supplied with the tank — you don't need to order this separately. This listing is for third-party cylinder installations only.
Choose the right cable length for your install
The PAW-TS2's 20 metre cable suits longer routing distances between the cylinder and the indoor hydromodule. For shorter runs, Panasonic also offer the PAW-TS1 with a 6 metre cable — check your installation layout before ordering to avoid unnecessary cable slack or an underlength run.
Key features
20 metre cable reach
Long cable length covers routing distances between the cylinder location and the indoor hydromodule without needing a cable extension or relocation of either component.
Copper sensor pocket
Inserts into a standard cylinder sensor pocket for accurate stem temperature reading — the preferred method for DHW sensing over strap-on alternatives.
Required for third-party tank installs
Wherever an Aquarea heat pump is paired with a non-Panasonic cylinder, this sensor (or the shorter PAW-TS1) is a required accessory — without it, the system has no way to read tank temperature for DHW heat-up cycles.
Direct hydromodule connection
Wires directly into the Aquarea indoor unit's dedicated tank sensor input — no additional interface or configuration hardware needed.
Genuine Panasonic component
Matched to the exact resistance and temperature characteristics expected by the Aquarea control logic — generic substitutes risk inaccurate readings and disrupted DHW or Anti-Legionella cycling.
Compatible across the Aquarea range
Used across Panasonic's monobloc, bi-bloc and hydro split L Generation systems wherever a third-party cylinder is specified.

Frequently Asked Questions
Do I need this sensor if I'm using a genuine Panasonic cylinder?
No — a tank sensor is factory supplied with every genuine Panasonic DHW cylinder. This standalone PAW-TS2 listing is specifically for pairing the heat pump with a third-party cylinder, where no sensor is included.
Should I choose the PAW-TS2 or the PAW-TS1?
Both do the same job — the only difference is cable length. Choose the PAW-TS2 (20 m) for longer cylinder-to-hydromodule runs, or the PAW-TS1 (6 m) where the cylinder sits close to the indoor unit. Avoid extending or shortening the cable yourself — pick the length that suits your installation layout.
Where does the sensor fit on the cylinder?
Into a standard sensor pocket on the third-party cylinder, at the position specified in Panasonic's hydraulic guide for your system configuration — typically the lower-to-middle section of the tank for accurate heat pump reheat sensing.
Can I use a generic temperature sensor instead?
It isn't recommended. The Aquarea control logic expects the specific resistance and temperature characteristics of the genuine Panasonic sensor. A generic substitute risks inaccurate tank temperature readings and disrupted DHW or Anti-Legionella cycling.
Is this sensor compatible with the Hydro Split L Generation range?
Yes — the PAW-TS2 is used across Panasonic's monobloc, bi-bloc and Hydro Split L Generation systems wherever a third-party cylinder is part of the system design.
How many sensors do I need?
One PAW-TS2 (or PAW-TS1) per third-party cylinder. If your system design includes a separate buffer tank, that typically uses a different sensor accessory — check your hydraulic schematic for the full accessory list.
