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

1️⃣ 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

2️⃣ 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 OFFiZone System Multiplexer allows up to five iZone systems (C225 modules) to be displayed on up to three screens (CCTSL#)

Image Added

1️⃣ Ports to CCTSL: 3 x RJ45 iZone Net ports for connection of up to three CCTSL screens

3️⃣ Antenna: The sensor antenna transmits the status of the sensor to the C225 module using iZone proprietary 433mHz wireless protocol

4️⃣ Batch number: Indicates the production batch number for this sensor

5️⃣ LED / Button: This is the button on the PCB see "2" above for details

6️⃣ Sensor: The sensor measures the temperature of the air inside the sensor

8️⃣ Pair Button: Press the pair button to pair the sensor to the system. See details in configuration on how to pair a sensor

9️⃣ Air circulation holes: It is important that the air circulation holes remain unobstructed to ensure good airflow through the sensor for accurate temperature control

1️⃣ 0️⃣ 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)

1️⃣ 1️⃣ Hardware version: This indicates the PCB part number (CRFS) and the hardware version number (1.3)

1️⃣ 2️⃣ 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

1️⃣ 3️⃣ 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

2️⃣ Ports to C225 modules: 5 x RJ45 iZone Net ports for connection of up to five C225 modules. Connection of C225 modules must start with CCPU1 port followed by CCPU2 etc

3️⃣ Transformer JST VA connection: Connect the iZone transformer here. Part number CT24ACE
