ATTENTION: Depending upon the style of system that your are going to control with
the Hot Shot Wireless Controller you may need to supply additional parts. Such as relays,
step-down transformers, Murphy switches etc. These items are suggested in the wiring
guides that follow in this manual.
NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a par-
ticular installation. If this equipment does cause harmful interference to radio or televi-
sion reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
 Reorient or relocate the receiving antenna.
 Increase the separation between the equipment and receiver.
 Connect the equipment into an outlet on a circuit different from that to which the
 receiver is connected.
 Consult the dealer or an experienced radio/TV technician for help.
15.21 INFORMATION to USER:
The users manual or instruction manual for an intentional or unintentional radiator shall
caution the user that changes or modifications not expressly approved by the party re-
sponsible for compliance could void the user’s authority to operate the equipment.
HOT SHOT OVERVIEW
HOW IT WORKS
Think of the HOT SHOT system as a 12-2 control wire going from the pivot to the irrigation
pump. When the Hot Shot Transmitter’s RELAY Input is activated, a 15 second delay timer is
started. After the delay timer has expired, the transmitter will send the (turn ON) command to
the receiver. This transmission will close the relay contacts at the pump to start water. When
the pivot is done irrigating or when the safety is tripped, the pivot will open the Hot Shot Trans-
mitter’s RELAY Input contacts and send the (turn OFF) relay command to stop water. Battery
backup in the transmitter will still allow the HOT SHOT to work in case of a pivot power out-
age. Each system is coded with its own four digit code so it will not interfere with other sys-
tems in the same area. The following manual has been prepared to provide details for Transmit-
ter installation and Receiver installation on electric and engine driven wells.
ATTENTION: All Hot Shot units have a designated GROUND Terminal. Hot Shot units must have
there ground terminal connected to a proper ground or grounding system as per the NEC (National Electri-
cal Code) and or your local and state electrical code guidelines.

MOUNTING
Cabinets are a weatherproof UV protected NEMA 4X cabinet with mounting ears on top and
bottom. The cabinet can be mounted on the side of a control panel, pole or any other surface as
long as the antenna does not have metal running within 12” of the antenna whip. If longer range
is needed, an external long range antenna can be used. Do not mount the HOT SHOT receiver
to the well engine or cover because the strong vibrations can be harmful to the unit.
CODE SWITCH SETTINGS
All transmitters and receivers will be shipped from the factory with preprogrammed field codes. This ensures
that your neighbor will not duplicate the same field code as your unit. Your field codes already match, so you do
not need to program any codes. If you ever need to replace a unit due to servicing, the field code can be pro-
grammed to match the existing or new add on units. FOLLOW THE EXAMPLE BELOW…

INDICATOR LIGHTS
POWER Signals that the Receiver has power and is ready to receive the code from the Transmitter.
STROBE Used for troubleshooting, this light flashes once for each of the four correct digits of the code received. The
light will stay on steady for one second if an incorrect digit of the code is received. Example: If the light
flashes two times and then goes on steady it is indicating that the third digit doesn’t match. If the light flashes
one time and goes on steady it is indicating that the second digit doesn’t match. If the light comes on steady
right away it is indicating that the first digit doesn’t match.
RELAY When this light is on it indicates that its corresponding relay has been activated.
SUPERVISION When this light is flashing it indicates that it has not received its correct code from the
transmitter in the past 3hrs. Sliding function switch #8 to its OFF position will turn off this indicator light.
SUPERVISION FEATURE
The Supervision Feature is a great way for checking at a glance the integrity
of the system. This feature will come on if the receiver has not heard it’s
correct code from the transmitter within the past three hours. The Supervi-
sion Light will begin to blink until the receiver hears it’s correct code again.
If there are two or more receivers on the same transmitter and the Supervi-
sion Light is blinking on both of them, it is indicating that the transmitter is
either turned off or malfunctioning. If only one out of the two receiver’s
Supervision Lights are blinking, it is indicating that that receiver is malfunc-
tioning and that the other receiver and transmitter are good.
OPTIONAL RELAY 2 AND 3
There is also a Supervision Light for each of the relays on the receiver.
These are there for when a receiver is going to use it’s other relays that are
controlled by different transmitters. This will tell you exactly which trans-
mitter is turned off or is not working properly.

MULTIPLE PUMP CONTROL
USING 1 HOT SHOT 810-3R-PLUS TO CONTROL UP TO THREE PUMPS.
A Hot Shot 810-3R-PLUS can come equipped to operate all three of its relays when the application requires it.
This style of receiver is convenient when the pumps are located close together or when their power supply comes
from the same circuit box. This will save money and time in eliminating the need for extra receivers at each pump.
See diagram below. One Hot Shot 810-3T-PLUS transmitter can control up to all three relays or three different
810-3T-PLUS transmitter can each control one relay. See diagram and field layouts below.

USING THE 1ST, 2ND AND 3RD RELAY TERMINALS
USED WITH THE EXTRA OPTIONAL RELAY INPUTS ON THE TRANSMITTER OR WITH THE
PUMP SELECTOR KIT.
When a Hot Shot Receiver 810-3RPLUS is going to be used with A Hot Shot 810-3TPLUS transmitter using it’s
#1, #2 and #3 SENSOR INPUTS or the Pump Selector Kit the receiver’s going to be used will need to use the
correct set of relay terminals to control the pump. This means that you will need to use the correct set of termi-
nals on the receiver for your desired control set up. The #1 Sensor Input on the transmitter will only turn ON
and OFF the #1 Relay Terminals on the receiver. The same goes for the #2 Sensor Input on the transmitter will
only turn ON and OFF the #2 Relay Terminals on the receiver and the #3 Sensor Input on the transmitter will
only turn ON and OFF the #3 Relay Terminals on the receiver. The picture below shows the layout of the Relay
Terminals on the 810-3RPLUS receiver.

ELECTRIC WELL HOOKUP
 Mount a 480v-120v step-down transformer to supply 120v to the receiver. The Hot Shot Re-
ceiver only requires 1 watt of power to operate. Hot Shot Systems suggest using a minimum of
a single phase 60 hertz 0.050kVA transformer. They are available for purchase through Hot
Shot Systems, just request when ordering.
 Mount a 3 terminal fuse block and a 120vac relay. Hot Shot Systems suggest using a 115V AC
coil relay. They are available for purchase through Hot Shot Systems, just request when or-
dering.
 Wire two, 480v conductors through the first two fuses (1/2 or 1 amp each) to the primary side
of the step-down transformer. Terminals may be different according to the transformer
installed.
 Wire the 120v X1 terminal of the step-down transformer through the remaining fuse (1 amp)
which then goes to the first 120vac input of the Hot Shot Receiver (120 volt polarity does not
matter).
 Wire the 120v X2 terminal of the step-down transformer to the neutral 120vac input of the Hot
Shot Receiver(see diagram on the next page).
 Add a jumper from the first 120vac terminal to the Hot Shot Receivers relay COM. terminal
(see diagram on the next page).
 Wire the NO. terminal on the Hot Shot Receiver to one side of the 120v relay coil.
 Connect the other side of the relay coil to the X2 terminal of the step-down transformer.
 Connect a wire from the Lighting Ground terminal of the Hot Shot Receiver to the ground
lug of the pump panel.
CAUTION: Never switch any voltage greater than 120v with the Hot Shot Receivers internal
relays. This will ruin the relay and void all manufacturer warranties. Use an externally
mounted 120v coil relay to switch all voltages greater than 120v. This will be shown later in
Electric Well Hookup section.
HOT SHOT RECEIVERS NEED TO BE TURNED ON BEFORE THE HOT SHOT TRANSMITTERS
ARE TURNED ON. HOT SHOT TRANSMITTERS ONLY TRANSMITT FOR 1 MINUTE. IF THE RE-
CEIVER IS TURNED ON AFTER THE TRANSMITTER IT WILL NOT OPERATE CORRECTLY UN-
TIL THE TRANSMITTER IS SET TO TRANSMITT AGAIN.

TYPICAL HOT SHOT RECEIVER HOOKUP TO KILL AN
ENGINE DRIVEN WELL
HOT SHOT RECEIVERS NEED TO BE TURNED ON BEFORE THE HOT SHOT TRANSMITTERS
ARE TURNED ON. HOT SHOT TRANSMITTER ONLY TRANSMITT FOR 1 MINUTE. IF THE RE-
CEIVER IS TURNED ON AFTER THE TRANSMITTER IT WILL NOT OPERATE CORRECTLY
UNTIL THE TRANSMITTER IS SET TO TRANSMITT AGAIN.
AT THE ENGINE
DO NOT mount the HOT SHOT Receiver unit to the well engine or engine cover because strong vibra-
tions can be harmful to the unit.
The diagrams below show a simple way to control an engine driven well using a simple 117 or 518 Murphy kill
switch. Supply power to the receiver by hooking up the 12v positive input on the receiver to the 12v positive
terminal on the battery. Run a wire from the Negative input on the receiver to the negative terminal on the bat-
tery or to a good ground connection. Install a jumper wire connecting the negative terminal to the COM terminal
on the receiver. Connect a wire from the N.C. terminal on the Hot Shot receiver to the S or the SW1 terminal on
the Murphy kill switch. Then install a simple on-off (bypass) switch between the NC and the S or the SW1 ter-
minal. This bypass switch is needed because there will not yet be any water pressure at the pivot and the re-
ceiver’s COM and NC contacts will not open until the water is pressured up and the pivot is requesting water.
Now, with the switch opened, it will act as a bypass to let the engine start and get the water pressured up. Once
the water is pressured up and the pivot is set to request water the receiver’s green RELAY ON light will illumi-
nate and open the contacts. Now, the bypass switch can be closed so that when the pivot is finished or the safety
is tripped the receiver will be sent a stop water signal, the receiver’s relay will close COM to NC. This shorts the
Sterminal to ground and kills the engine. Other variations and Murphy Kill switches will work as well.
