Aqua-Scope HEAWIE02 Warm Water Heating Monitor Instruction Manual

Aqua-Scope HEAWIE02 Warm Water Heating Monitor

Product Description

The Aqua-Scope monitor for hot water heating systems records the temperature and pressure of the water in the heating circuit. of the water in the heating circuit. It can be installed either in the flow or in the return.

The device consists of two parts:

• Main housing for signal processing and radio communication with battery compartment.
• The external sensor head is connected to the water pipe. The stainless steel sensor head has a silicon sensor mounted in silicone oil for highly accurate and low-noise pressure measurements in a wide operating range. The measuring range for pressure is between 1 and 10 bar. The sensor values are converted into digital values directly in the measuring head to suppress interference from the connection to the main housing. In addition, the temperature of the liquid medium is measured directly at the stainless steel diaphragm and is therefore very precise.

The sensor can send an alarm message if freely definable threshold values are exceeded or notreached. The sensor’s polling frequency can be set between 0.1 second and several minutes and defines the battery life. For a measuring interval of 1 second, a battery life of approx. 10 years is calculated. The device connects to WIFI. Your mobile app help setting up the connection and gives access the data and presents current and historical values and events.

The device is powered either via an external power supply with USB-C power supply unit or via an optional internal ER26500 battery (Bobbin Cell C).
Both the sensor head (IP67) and the main housing (IP65) are waterproof and can be used outdoors or in particularly humid and/or dirty environments.

Installation

The sensor head is screwed into 1/4 inch inspection openings of existing warm water pipe system.

Reset to Factory Default State
The factory default state is indicated by the LEDs blinking green/red. Please push the button after the initial buzzer beep (but not earlier!) and keep it pushed for 5 seconds. After 5 seconds you hear a low- frequency sound. Now release the button! This reset sequence will delete all settings including network access credentials.

WIFI Network Setup

Download the App “Aqua-Scope” from your App store and register yourself as new account with email and password. You may want to use the QR codes above for a convenient access to your mobile app store. Follow the instructions on the app.

If you don’t want to use the Aqua-Scope Mobile App or if you want to integrate the device into your own monitoring system you can also setup and operate the device using any standard web browser. Please refer to the Aqua-Scope Developers Manual for more information, available at www.aqua- scope.com

Functions and Usage

Every 15 minutes (when mains powered) or every hour (when battery operated) the device reports the following sensor values:

• Pressure of the water,
• Temperature of the water right at the sensor head.

The sensor values can be accessed in the Aqua-Scope App or they are reported into the network when integrated into third party systems. The device offers a low watermark and a high watermark threshold that can be defined using the mobile app. If the valued are exceeded an under pressure or overpressure alarm is issued.

Beside the water-related alarms the device also reports certain device-related conditions as alarm:

• No external sensor head connected
• Head present but no contact to water
• Battery Low
• Mains Power lost
• Bad communication network quality

All these alarm conditions are monitored continuously. Alarms are indicated on the device with red LED and buzzer sound (both can be disabled in the app) and they are reported into the Aqua-Scope Cloud and shown in the Aqua-Scop App. If the alarm condition disappears the alarm is reversed but will remain in green color in the app for information. Swiping them in the apps home page finally deleted them.
Further alarm reactions such as email, push notification or even a voice call can be defined in the AquaScope App

LED-Signals

• All colors blinking: device boots up
• Yellow blinking: Devices tries to connect to network
• Red fast blinking (mains powered) or steady: Alarm
• green/red blinking: factory default
• 3 times green blinking plus buzzer: Device connected to network successfully and is ready to work
• Blue glowing (mains powered) or all LEDs off (battery operated): Device is operating

Battery Operation

If the device is battery-operated all focus in on extending battery life. The battery life depends on several factors:

• Presence of a Pressure Reduction Valve: If a PRV is present the device will draw significantly less power and the battery life extends at least by a factor of 2.
• Interval of status reporting. In mains power mode the device will report its status every 20 seconds and receive commands from the app/Cloud. In battery mode the device wakes up every hour only.
• Hence, every command such as open/close of the valve or setting certain parameters will be executed with delay.
• All status data such as temperature of water, consumption etc. are only reported once per hour (in mains every 15 minutes)
• The stand-by animation of blue led glowing is turned off in battery mode.

You find an estimation of the battery lifetime in the app under ‘Devices’. With PRV the battery will last about 8…10 years, without PRV the lifetime is about 4 years.
