*Due to continuing improvements, specifications may be subject to change without notice
*Do not use steel pipes as water pipes.
*Keep the water circulated at all times. Blow the water out of the pipes if the unit will not be used for an extended period time.
*Do not use ground water or well water
*Do not install the unit in an environment where the wet bulb temperature exceeds 32°C
*The water circuit must use the closed circuit
*There is a possibility that the unit may abnormally stop when it operates outside its operating range. Provide backup
(ex.boiler start with error display output signal (blue CN511 1-3)) for abnormal stop.

1. The broken lines indicate the optional parts,field-supplied parts,and field work. 2. Dashed lines indicate sub box 7. When cabtyre cable is used for the control cable wiring,
use a separate cabtyre cable for the following wiring. Using the same cabtyre cable may cause malfunctions and damage to the unit.
(a) Optional remote controller wiring (b) No-voltage contact input wiring (c) No-voltage contact output wiring (d) Remote water temperature setting
8. Use a contact that takes 12VDC 1mA for no-voltage contact input. 6. Leave a space of at least 5 cm between the low voltage external wiring
(no-voltage contact input and remote controller wiring) and wiring of 100V or greater.Do not place them in the same conduit tube or cabtyre cable as this will damage the circuit board.

3. Faston terminals have a locking function.
Press the tab in the middle of the terminals to remove them. Check that the terminals are securely locked in place after insertion.
4. The symbols of the field connecting terminals are as follows.
:Terminal block : Connection by cutting the short circuit wire
5. The method of input signal of operation can choose one of optinal remote controller
or no-voltage input.
10. Use a 4-20mA signal output device with insulation.
Feeding 30mA or more current may damage the circuit board.
11. For prevention of damage of the pump, SWS2 is set in "A"(factory setting). 12. Use a contact that takes 250VAC, 10mA or above, and 1A or below for no-voltage
contact output.
Change the slide switch SWS2 B(automatic) in Test Run.

1. Product Specifications
External water temperature sensor TW-TH16
1. Parts that are required to install an external water temperature sensor
A) External water temperature sensor
B) Wiring to connect the sensor and the unit*
C) Wiring terminals to connect the wiring to the sensor and the terminal block
on the unit
(Four for M4 screws)*
* Items B) and C) are field supplied.
2. Installing the external water temperature sensor
Install the external water temperature sensor where the water pipes merge or on the load-side tank.
Install horizontally or vertically on top of the pipe.
When installing horizontally, make sure the wiring faces down.
3. Wiring the external water temperature sensor
Connect the external water temperature sensor wiring to the terminal block in the control box on the unit as shown in
the figure below.
Connect the sensor wiring to terminals T1 and T2 of the 12-pin
terminal block in the control box on the unit.
Connect the shield to the earth terminal.
Thread the wiring to the external water temperature sensor
through parts b) through d) as shown in the figure at right. Attach
M4 terminals (not supplied) to the wirings, and connect them to
e) and f) (terminals A and B).
After the wiring is connected, securely tighten the tightening
screw d), and then caulk the gap between the wiring a) and the
tightening screw to keep water from entering.

Flow sensor kit
1. Tools and materials needed for an installation of the flow sensor
Have the following tools and materials ready before starting.
2. Flow sensor installation
Install the flow sensor on the pipe by following steps (1) through (3) below.
Install the flow sensor between the secondary-side pump and the heat exchanger.
Refer to the Installation/Operation Manual of QAHV-N560YA-HPB for details.
Materials Quantity *1 Size: HEX 30
1 Flow sensor 1 Tightening torque: 50 N·m ± 10%
2 O-ring 2 *2 Only use silicon grease.
3 Quick fastener 2 *3 Select the following type of extension wiring.
4 Coupler 1 (IN-side) 1 Wiring diameter 0.812 mm or larger
5 Coupler 2 (OUT-side) 1 Type CVVS or CPEVS
6 Cable tie (short) 1 Maximum length 20 m
7 Cable tie (long) 1 to 2 *4 Select the type of terminal block that meets the following.
- Water-proof
Tools and locally procured materials - Usable at or above 15 V

(1) Install an O-ring on the flow sensor and coupler 2 (OUT-side).
Both of the parts shown at left have a groove on the
them into the groove.
* The end with a smaller bore is the IN-side. Be sure to install
them in the correct orientation.
(2) Connect a coupler to the pipe, and connect the flow sensor.
Attach the coupler to the pipe so that
the IN-side of the coupler faces up
and the OUT-side of the coupler
faces down. (Water flows from top
to bottom.) The incline of the pipe
should not exceed 5 degrees.
Keep the sensor away from water.
The flow sensor is 71.5 mm long.
Keep an appropriate distance
between the couplers.
Fit the flow sensor to the coupler.
(3) Install the quick fastener on the pipe.
Insert the flow sensor into the couplers,
the flow sensor and the couplers are
connected to each other. Keep the
quick fasteners out of contact with the
wiring so as not to damage the wiring.
Hold the wiring to the quick fastener
with a (short) cable tie as shown in the
damaged.
Extend the length of the wiring as
necessary, using a terminal block.
Keep the wiring and the terminal block
dry.

3. Flow sensor wiring connection
Connect the wiring by following steps (1) through (4) below.
4. Cautionary notes
Note the following when performing wiring work.
Turn off the power before performing wiring work to avoid electrocution.
Watch for sharp edges of sheet metal.
Keep external wiring at least 5 cm away from wiring that carries 100 V or higher.
Do not bundle the wiring together with strong current wiring.
Connect wiring in a way that minimizes electrical noise interference. Shield the wiring to minimize external effects.
Install the flow sensor indoors, and insulate it as necessary to keep it from being exposed to subzero temperatures.
Keep the wiring and the terminal block dry.
