MAINSLINK
Application example: WORCESTER-BOSCH Boiler Installation:
Operation
When the Boiler switches the Pump ON, MAINSLINK-TX is switched
Live, then, MAINSLINK-RX Lout will automatically switch the pump on.
Warnings:
•
Product is not independently isolated, ISOLATE the mains electricity supply before removing the
cover and observe any relevant safety precautions. Maintenance to the product that involves
removal of the cover should only be carried out by a competent person or qualified electrician.
•
F2 Fuse rating is 4A (T) 250 H (Ceramic). Replace fuse with same type and rating.
•
Relay is rated at 10A peak, and 5A constant.
•
Product must be connected to a switch fused spur/supply or BS1363 Plug. A single Fuse Spur is
recommended to supply the Boiler and MAINSLINK jointly so that they are isolated together.
Jumper Link Setting:
There are three Jumper Links which may be used to configure the following:
Link
WDOG
WDOG
MODE
MOM/LAT
MODE
MOM/LAT
WDOG: WATCHDOG:
This provides improved reliability and security, useful with electrically noisy Loads. When the WDOG links are
fitted MAINSLINK-TX automatically sends a repeat background "watchdog" RF signal and MAINSLINK-RX
expects to receive this signal. If the WDOG signal is not received within 90 seconds, the output will drop
out and comms LED will flash.
In the event of a Power Loss at the receiver, if the transmitter is ON the Watchdog signal will auto recover
the MAINSLINK-RX to Switch ON
MODE:
FM: Fast operation shorter range (Line of sight upto 500m/100m in buildings)
This mode is recommended for general operation.
LORA Mode 3: Slower operation Long range (Line of sight upto 5Km/1Km in buildings)
This mode can be used where additional RF penetration / range is required.
-
MOM/LAT Momentary or Latching Output
MOMENATRY: Used for MAINSLINK TO MAINSLINK.
LATCHING: Select this when MAINSLINK-RX is controlled by a Remote transmitter e.g. pocket keyfob.

Switching Lower Power LED Lights:
Mainslink-RX incorporates a "snubber" protection circuit which is
recommended with Inductive Loads such as a Motor or pump.
If switching lower power LED lighting the snubber circuit can cause
the LED lights to faintly glow when switched off.
To remove the snubber, remove Jumper link J2 on the rear of the PCB
(as image shows).
Pairing a MAINSLINK-TX to a MAINSLINK-RX
NOTE: This system does not require pairing, they are supplied ready to operate!
1. Apply a 230Vac supply to the MAINSLINK-RX
2. Briefly swipe a magnet along right side as shown
3. The GREEN comms LED will flash 3 times to show "in Pairing
Mode".

5. Apply a 230Vac supply to the MAINSLINK-TX
6. Briefly swipe a magnet along right side as shown
7. MAINSLINK-TX will now send a special Pairing message
8. The MAINSLINK-TX and MAINSLINK-RX will now Auto pair
together - allow 15 secs.
Erasing a MAINSLINK-RX
To erase the system hold a magnet beside the top right side
of the enclosure until the Green COMS LED is ON solid
(about 5 seconds).
