TR1 TR2 RF Transceiver Pack
Operating Instructions
Important: Keep this document
Prior to operation, it is necessary to complete all required settings described in this section.
CAUTION!
Before commencing any work on the electrical connections, you must first disconnect the device from the mains. None of the 230V connections must be live until the installation has been completed and the housing is closed. Only qualified electricians or authorised service staff are permitted to open the terminal box.
There are parts that carry mains voltage behind the cover. The terminal box must not be left unsupervised when open. (Prevent non specialists and especially children from gaining access to it.)
Ensure that this wireless enabled receiver is installed 1 metre from any metalic object, television, radio or wireless internet transmitter.
The TR1 and TR2 RF Transceiver Pack is used to establish a wireless link between 2 locations. It can wirelessly send a signal from the TR1 to the TR2 and from the TR2 back to the TR1 if required.

2. Mounting
The TR1/ TR2 Transceiver should be wall mounted in an area within 20 metres distance of the wireless thermostat.
It is important that the receiver is mounted more than 1 metre away from metal objects as this will affect communication with the thermostat.
The receiver should also be installed at least 1metre from any electronic devices such as radio, TV, microwave or wireless network adaptor.
The unit can be fitted to:
- Recessed conduit boxes
- Surface mounting boxes
3. Installation
Slacken the fastening screw on the bottom of the receiver with a philips screwdriver.
The receiver is hinged and can be opened 180 degrees. Mount the unit as described in section 2. Wire the unit as described in section 1. Close the receiver and tighten the fastening screw.

- Manual override
- Connect button
Wireless connect: Pressed to initialise the pairing process with the other receiver.
Manual override: This button will manually override the system. (Only when disconnected)
Wireless connect indicator: This LED will flash on receiving wireless signals. If it is constantly blinking, the TR1 transceiver has been disconnected from the TR2.
5. To connect the TR1 to a TR2
Press the ‘ Connect ’ button on TR1 and TR2, the green light on TR1 and TR2 will begin to flash.
After connecting successfully, the red LED will be constantly ‘ ON ’ for the TR2.
