How your TR1 TR2V2 works

• Your TR1 TR2V2 is used to send a wireless signal from one location to another when running Cables is difficult, expensive, or otherwise not an option.
• The product comprises two devices: a TR1V2 and a TR2V2. Both devices are pre-paired during manufacturing for user convenience.
• When 230V is applied to the Live in terminal of the TR1V2, the COM and Live out connection closes, which sends voltage from Live out on the TR2V2.
• It is possible to send a wireless signal in one direction or both.
• When a signal is sent from the TR1V2 to the TR2V2, a green light will activate on the TR2V2.
• When the TR2V2 sends a signal to the TR1V2, a green light will activate on the TR1V2.
• Common uses include sending a signal from a programmer to a boiler or hot water cylinder that is in a different location. These are also used to control pump overrun and many other applications.
• It is possible to have more than one set of TR1, TR2V, 2and, where required.
• Please see pages 9-13 for wiring examples

CAUTION: Installation should only be carried out by a qualified person and by wiring regulations.

Switching  Options

Mains Switching

• Link L to 3

Low Voltage Switching

• Remove the external controls link from the boiler PCB.
• Connect 2 and 3 to these terminals.

Mounting & Installation

1. The TRIV2 should be wall-mounted in an area within 30 metres of the TR2V2. Both TRIV2 & TR2V2 must be mounted more than 25cm away from metal objects, as this will affect communication. The TRIV2 & TR2V2 should be installed at least 1 metre from any electronic devices such as radio, TV, microwave, ve, or wireless network adapter. They can be fitted to
   1. Single-gang recessed back box.
   2. Surface mounting boxes
   3. Directly mounted on a wall.
2. Use a Phillips screwdriver to loosen the screws of the backplate on the bottom of the TRIV2 & TR2V2, lift upwards from the bottom, and remove the backplate.
3. Screw the backplate to the wall with the screws provided.
4. Wire the backplate as per the wiring diagram.
5. Mount the TRIV2 & TR2V2 on the backplate, making sure the pins and the backplatcontactsts are making a sound connection. Push the TRIV2 & TR2V2 flush to the surface and tighten the screws of the backplate from the bottom.m

Wiring Examples

Example  One way RF Switch: Programmer to Boiler – Mains Switching

TR1V2 
On TR1, when Live in receives 230V from the programmer, TR1 sends a wireless signal to TR2.

TR2V2
On TR2, the COM & Live out contact closes, sending 230V to activate the boiler.

Installation Notes
