## Welcome to HotBot
HotBot makes geysers intelligent - ensuring
that homes have hot water when they need
it, while saving the most on electricity.
It achieves this with advanced hardware
that connects to your geyser, artificial
intelligence which helps decide when
to turn geysers on and off, and an
app through which users can set their
preferences and override the system at any
time.
HotBot should be installed by a qualified
plumber or electrician. This manual
will guide you through the installation
of HotBot’s hardware - a sophisticated
product designed for easy installation.

## How to install HotBot
*HotBot installation involves four*
*simple stages:*
**A INSTALL SENSORS**
**B INSTALL CONTROLLER**
**C VALIDATE INSTALLATION**
**DHANDOVER**
---
## Install sensors as per A. INSTALL SENSORS
## Turn off power at distribution board and isolator
You are working with high voltage
AC power. Take all necessary
precautions, including using a
multimeter to test that power is off
before commencing work.
Clip to cold water inlet pipe
as close as possible to the
geyser
1. Remove thermostat
***2. Note current setpoint***
***and set to 65˚C***
$$
65\,^{\circ}c
$$
3. Insert sensor to end of
thermostat pocket
4. Hold sensor in place and
carefully reinsert the
thermostat
**TIP:** *If you need to rewire the*
*thermostat, do so at the same*
*time (see Section B.5)*
Clip cable to hot water outlet
pipe 0.5m from geyser

## FLOW NOTES:
*The arrow on the flow meter*
*should point in the direction of*
*flow. Water supply to the geyser*
*should be shut off before installing.*
*The flow meter allows reverse flow*
*to comply with SANS 10252-1.*
## VALVE NOTES:
*A relief must be present*
*or installed between*
*the valve and geyser.*
*Water supply to the*
*geyser should be shut*
*off before installing.*

**Install controller**
---
## 3Mount box on beam or wall
a) Choose location:
• No more than 2m from each sensor
location, with the lid and cable access
unobstructed, within reach of the
existing power supply cable, less than
1m from the geyser’s thermostat.
b) Mount according to surface:
**• On a beam:** use the supplied giant cable
ties for rapid mounting.
**• On a wooden wall:** use the supplied
fasteners.
**• On a masonry or concrete wall:**
drill 8mm holes and use the supplied
fasteners and wall plugs.
**IMPORTANT:** *Ensure that the box is mounted upright*
*(with the cables exiting the bottom of the device).*
---
## 4Plug in sensors
Plug sensors into ports with matching
colours, and press the cable into the
corresponding slot
**NOTE:** *these colours are intended only as guides*
*for plugging sensors into correct ports, and have*
*no safety meaning.*
## 5 Wire power
## a) Choose wiring method
The easiest way to wire HotBot is to cut the
existing power supply cable to the geyser
and connect at this point. Do this if there is
sufficient slack in the power supply cable to
connect HotBot.
## If this is not possible:
Remove the power supply cable from the
thermostat and wire into the “In from mains”
terminal on HotBot.
Using a new piece of power cable (supplied),
connect the “Out to geyser” terminal to the
thermostat.
---
b) Wire
Wire power into and out of HotBot in
accordance with markings and as per
National Wiring Standards.
**NOTE:** *the geyser must be earthed*
Example wiring:
---
## 6Turn on power at distribution board and isolator
Again take all necessary precautions.
corresponding slot
## To finish:
Organise and neaten up the cables with
supplied cable ties.
**NOTE:** *some controllers have a white plug above*
*the sensor ports on the left hand side. This should*
*not be plugged into anything.*
---
It’s time to make sure that everything is
working as expected and to collect some
information about the system. With
your help, HotBot will run several digital
checks on the system and provide you
with feedback.
**1**
If you installed a flow meter, run hot water
for 10 seconds
**2**
Visit **install.plentify.io** and log in with your
email address.
*Scan to visit*
**install.plentify.io**
3
Search for the HotBot ID. This ID can be
found on the side of HotBot under the QR
code.
**4**
Select “Run validation tests” and enter
required details.
**5**
Select “Capture geyser data” and enter details
about the hot water system.
---
6
View results of validation tests, and address
any issues as instructed in the app. The LED
light on the front panel of the HotBot device
will light up - different light colours indicate
the following:
Blue
Yellow
No issues with battery or signal
Flashing red
No signal
Solid red
No battery
- check the battery tab has
been removed
Battery present, but not
sufficiently charged
---
## D. HANDOVER
Now that the installation has been
completed, it’s time to hand over to the
end user and do some final checks:
## IMPORTANT:
Ensure that any existing timers
have been disabled by either (1)
bypassing or (2) setting to always
on and (if relevant) setting digital
thermostat to full.
Give them the supplied envelope
which contains instructions for
them to set up the app, schedule
when they want hot water, and
begin enjoying the full HotBot
experience.
---
## CHECKLIST:
Ensure that power has been turned
on at both the DB board and
isolator.
Ensure that any existing timers
have been disabled.
Ensure the battery tab is removed.
Ensure the thermostat has been
set to 65°C.
$$
6 5 ^ {\circ} \mathrm {C}

Ensure all sensors are plugged
in correctly and to their

## Safety precautions
• Always turn off power to geyser at
isolator switch and DB board before
opening the device
• Do not attempt to replace the
rechargeable battery or the coin
cell battery (present in the OF 5000)
unless you are a Plentify approved
technician instructed to do so by
Plentify and have been provided by
Plentify with the correct replacement
batteries (SKUs: BAT-LIIO-0001 for the
rechargeables; BAT-LIIO-0003 for coin
cells). Risk of explosion if batteries are
replaced by an incorrect type.
• Dispose of used batteries at a
battery recycling drop-off location,
available for free in many stores (e.g.
Woolworths).

• Ensure that the geyser circuit has
a circuit breaker with the correct
amperage rating to match the kilowatt
rating of the geyser (2kW=15A,
3kW=20A, 4kW=25A), not to exceed
30A or the rating of the supply cable.
• None of the sensor ports are ethernet,
telephone or Power over Ethernet
ports.
• Only connect Plentify-supplied cables
in their corresponding ports. Do not
attempt to connect any third party
cables or devices.
• If anything is unclear or ambiguous,
please confirm with Plentify before
proceeding.
