Introduction
The CB12RF is an advanced RF control box designed to address the key installation and functionality challenges. Featuring IT600 and ZigBee 3.0 device compatibility, it allows seamless integration with other smart home devices and systems.
Compact and streamlined, the CB12RF is ideal for manifold installations. It supports up to 2 actuators per zone, adapting flexibly to diverse heating requirements. Additional features include earth terminals for enhanced safety and multiple operating modes (Master, Slave, or Off) to ensure compatibility with both existing iT600 products and further ZigBee 3.0 systems.
With built-in WiFi for cloud connectivity and firmware updates, the CB12RF combines cutting-edge technology and user-friendly features, making it a powerful and efficient solution for modern heating control.
Product Compliance
This product complies with the essential requirements and other relevant provisions of Directives 2014/53/EU and 2015/863/EU. The full text of the EU Declaration of Conformity is available at the following internet address: www.saluslegal.com.
2405-2480MHz, <20dBm
Safety Information
Use in accordance to national and EU regulations. Use the device as intended, keeping it in dry condition. Product for indoor use only. Installation must be carried out by a qualified person in accordance to national and EU regulations.
(1) Fuse
The wiring center includes fuse protection to safeguard its components and connected devices. In the event of a wiring center failure, the fuse is designed to blow first, preventing damage to other parts or connected equipment.
Note: Fuse replacement should be done when the wiring center is disconnected from power supply.
(2) Power Supply
Power supply for wiring center is 230V ~ 50Hz
Features of the installation:
- three wires with PE protective conductor
- made in accordance with applicable regulations
(3) Pump Output and LED
The pump output is 230V with three terminals: L (Live), N (Neutral), and PE (Earth). The PE terminal must be connected as the earth connection. When any thermostat connected to the control box calls for heating or cooling, the pump output is activated. If no thermostat calls for heating or cooling, the pump output is deactivated. A built-in 3-minute delay is included for pump activation and deactivation. A green LED indicates the current state of the pump output.
(4) Boiler Output
The boiler output is a volt-free connection that controls the boiler in the heating system. It activates 3 minutes after receiving a heating signal from any paired thermostat. The output deactivates and turns the boiler off when the last thermostat stops sending a heat demand, following the delay set on the jumper.
(5) Heat / Cool Changeover
The HEAT/COOL switch is a volt-free dry contact. When the switch is open, the control box operates in HEAT mode. When closed, it switches to COOL mode. During a mode change, the control box notifies all connected thermostats to adjust their system mode accordingly.

(6) Dew Point
In Cooling mode, the control box monitors condensation through a connected dew sensor. If condensation is detected, the control box signals all connected thermostats to stop cooling until the condensation clears, ensuring system protection and efficiency.
Each system supports a total of 12 zones, allowing a maximum of 12 thermostats to be paired. A single thermostat can be paired with multiple zones.
- Zone Control: Each zone is controlled by its own 0.5A Triac, designed exclusively for actuators. No other devices should be connected to the zones.
- Actuator Limit: Up to 2 actuators can be connected per zone (System supports up to 24 actuators).
Each zone has a green LED to display the relay state.

(8) Master – OFF – Slave Selection
The slide switch allows the user to select if the control box operates as Master or Slave. The default position is OFF, where no communication occurs, and the device only detects switch changes.
- Master: The control box acts as a coordinator, creating its own network for iT600 and ZB3 devices to join.
- Slave: The control box functions as an end device, joining a Master network, Computime universal gateway, or other compatible ZigBee gateways.
(9) IT600-ZigBee 3.0 Jumper Selection
This switch allows the user to select whether the control box operates as an iT600 or ZigBee 3.0 device.
- IT600 thermostats: VS range, Quantum range, HTR range, TS600.
- ZigBee 3.0 devices: Elypso
Note: If you have a mix of thermostats you must use IT600
iT600 Selected
Zig-Bee 3.0 Selected
It is only active when the MASTER-OFF-SLAVE switch (5) is set to SLAVE.
(10) NC-NO Actuator Jumper Selection
The NC/NO jumper allows selection of the actuator type, with the default set to NC (normally closed).
- Switching to NO means normally open actuators are connected.
- Switching to NC means normally closed actuators are connected.
NC Actuator Selected NO Actuator Selected
The control box and connected thermostats must use the same actuator type (either NC or NO) to ensure compatibility. The Zone LED indicates power supply to the actuators:
- For NC actuators, power opens the valve.
- For NO actuators, power closes the valve.
Press the Reset button to re-power the CB12RF device. Use a sharp object in order to press the button through the pinhole
Please note, this action does not perform a factory reset and will not erase any settings or configurations.
(12) Boiler Delay Jumper
The DELAY OFF jumper allows users to set a boiler turn-off delay of either 0 or 15 minutes, with a default of 0 minutes. In a Master-Slave system, the delay is determined by the Master jumper setting.
0 MIN 15 MIN
Selected Selected
(13) INT-EXT Antenna Jumper
For optimal RF performance, use the jumper to select between the internal or external antenna.
- INT Position: Uses the on board RF antenna.
- EXT Position: Uses an external antenna connected to the antenna terminal.
INT Selected EXT Selected
Default setting: INT (Internal Antenna)
Form network
Set the MASTER-OFF-SLAVE switch (8) to MASTER and power on the Control Box. The ZigBee LED will flash. Long press the network button to start forming the network—ZigBee LED turns steady ON, and the Status LED flashes. Once the network is formed, the Status LED becomes solid ON, and the ZigBee LED flashes in the “Open Network” pattern for 10 minutes.
Join network
Set the MASTER-OFF-SLAVE switch (8) to SLAVE and power on the Control Box. The ZigBee LED will flash. Long press the network button to start joining a network—ZigBee LED turns steady ON, and the Status LED flashes.
Once joined, the Status LED becomes solid ON.
Factory Reset
Holding the NETWORK button for 10 seconds restores the Control Box to its default settings by removing it from the ZigBee network, clearing all associated devices, bindings, and reporting tables, and erasing WiFi credentials.
Additionally, the ZigBee LED indicates the reset status by flashing the red color.
Long press the Zone Button on the Master Box to start pairing; the Zone 1 LED will flash to indicate it is ready. To cancel the selection, long press the Zone 1 button again, and the LED will stop flashing.
Same principle applies for each of the zones.
In order to commission WiFi on the CB12RF, Bluetooth Low Energy (BLE) is automatically enabled for 15 minutes after the device is powered up. During this time, the WiFi State LED flashes. If needed, BLE can be reactivated by pressing the button (14), which restarts the 15-minute timer. Each press resets the timer and BLE remains active for the full duration of 15 minutes before automatically deactivating. While BLE is inactive, the WiFi State LED stays off.
Used in order to find and bind with the RF Receiver for both boiler and pump.
