CRFS#: Wireless Temperature Sensor - Install Guide

The CRFS# is a wireless sensor used for the control of zone temperatures and air conditioning units on iZone systems

Open

Open

Fascia: The fascia is moulded from clear polycarbonate plastic wit a colour applied to the back of the fascia to give it a coloured glass look

The sensors are available in White, Black and Ocean Mist

Button: The button is used to turn the zone "ON" in Climate Control mode or "OFF"

When turned On the button will appear to be blue for a few seconds indicating it has been turned ON (As shown in the picture)

When turned Off the button will appear to be red for a few seconds indicating it has been turned OFF

Antenna: The sensor antenna transmits the status of the sensor to the C225 module using iZone proprietary 433mHz wireless protocol

Batch number: Indicates the production batch number for this sensor

LED / Button: This is the button on the PCB see "2" above for details

Sensor: The sensor measures the temperature of the air inside the sensor

Zone Selector: Set the selector to match the zone number that the sensor is located. Zone selection is from 1-14

Pair Button: Press the pair button to pair the sensor to the system. See details in configuration on how to pair a sensor

Air circulation holes: It is important that the air circulation holes remain unobstructed to ensure good airflow through the sensor for accurate temperature control

Backing plate: The backing plate is made from ABS plastic and the PCB is clipped into the backing plate. Standard colour for the backing plate is white. Black is also available (as shown in the picture)

Hardware version: This indicates the PCB part number (CRFS) and the hardware version number (1.3)

Battery: The CR2032 battery is clipped into the battery holder. To remove the battery requires a small screw driver or similar tool to ensure they are child proof

The battery should last between 1-2 years before requiring replacement

Mounting holes: The backing plate mounting holes are designed to suit a standard light switch wall box. If the wall is not perfectly flat do not over tighten the screws as this will bend the backing plate and may result in the fascia not clipping on securely

1. Remove the wireless sensor cover gently, using a flathead screwdriver

2. Remove the battery tab

3. Press and hold the PAIR button on the sensor and press PAIR icon on the wall controller

4. Blue LED will flash rapidly and the wall controller prompts updating information

5. Using a small flathead screwdriver, set the dip switch number on sensor to match it with the zone number that sensor will be installed

6. Click on Settings > Configuration > Configure Aircon > insert system password ‘wamfud’> Click on zones tab and change zone type to WIRELESS

7. Click on Settings > Configuration > Configure Aircon > insert system password ‘wamfud’> Click on AC UNIT tab and change controlling sensor to “ZONES”

8. Back in main menu, click on the zones summary and press the sensor button

9. When LED turns blue on sensor, zone status will change to climate control

10. When LED turns red on sensor, zone status will change to close

11. Make sure you see all three temperature setpoints, actual temperature and induct temperature on the screen

12. Put the sensor cover back on the sensor and install it on the wall according to iZone standards
