Description
MAINSLINK is a plug and play solution to replace a switched live cable. When 230Vac
“LIVE” is input to the transmitter, the receiver provides a 230Vac “LIVE” switched
output at its screw terminals.
MAINSLINK utilises the RF Solutions state of the art RF-LoRa Spread Spectrum Fre-
quency Modulation transceiver design to achieve a the highest performance / Range
available from any Radio System, upto 1Km within a building environment and 5Km Line
of sight.
When used as a Pump Overrun solution the TX is placed by the boiler and connected to
the Boiler Pump output. The RX directly drives the pump from its Live switched output

Warnings :
• Product is not independently isolated, ISOLATE the mains electricity supply before re-
moving 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 BS 1363 Plug. It is rec-
ommended a single Fuse Spur is used to supply the Boiler and MAINSLINK-PRO jointly so
that they are isolated together.
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.
Switching Lower Power LED Lights
Mainslink-RX incorporates a “snubber” protection circuit
which is recommended with Load connections 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).

Jumper Link Setting
There are three Jumper Links which may be used to configure the following
Link Open Fitted
WDOG Watchdog OFF Watchdog Active
MODE FM LORA Mode 3
MOM/LAT Momentary Latching
WDOG
MODE
MOM/LAT
WDOG - WATCHDOG
This provides improved reliability and security, useful with electrically noisy Loads.
When the WDOG link is fitted each MAINSLINK automatically sends a background watchdog RF signal
and expects to receive a corresponding WDOG signal from its partner.
If the WDOG signal is not received within 90 seconds, the output will drop out and comms LED will
flash.
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.
NOTE: In this mode a transmitted signal can take 2 seconds to trigger the receiver.
MOM/LAT - Momentary or Latching Output
Sets the Relay changeover contacts to operate as Momentary or Latching.
MOMENATRY: Used for MAINSLINK TO MAINSLINK.
LATCHING: Select this when MAINSLINN-RX is controlled by a Remote transmitter - e.g. pocket keyfob.

1. Apply a 230Vac supply to the MAINSLINK-RX
2. Briefly swipe a magnet along left side as shown
3. The GREEN comms LED will flash 3 times to show “in Pairing Mode”
Erasing a MAINSLINK-RX
1. Apply a 230Vac supply to the MAINSLINK-TX
2. Briefly swipe a magnet along left side as shown
3. MAINSLINK-TX will now send a special Pairing message
4. The MAINSLINK-TX and MAINSLINK-RX will now Auto pair together
- allow 15 secs.
To erase the system hold a magnet beside the top left side
of the enclosure until the Green COMS LED is ON solid
(about 5 seconds).

Product Revision History
The below shows the product Development / Improvements that have been made to the
product through the product Lifecycle
MAINSLINK REVISION CHANGE HISTORY
Date Eng
Change Product Change / Improvement
New
Revision
18/10/18 ECN314
Update to firmware to prevent lockup when pairing in Mode 3.
Using Mode 3 only, the length of RF packet is >2secs, if, when in LEARN mode
both MAINSLINKS’ transmit at the same time then they can both be in the
position of waiting for a response.
New F/W randomly sets one as master on initial RF signal, then only one re-
sponse is received removing the RF competition.

12/2/19 ECN319 6
If the input (RX signal) immediately coincides with an output (TX signal) in very
rare cases (two reported) the RF transceiver has locked up, this is a fix to this
issue.
1/9/19 ECN331 8 Addition of LEDs on Front panel for visual indication or operation. Improvements
to the enclosure.
Version Identification
The product part number and revision of build can be viewed on the white label on the outside of the enclosure and
also on the Circuit board assembly.
