Installation Procedure Steps
A summary of the installation steps are as follows:
1. Apply all safety measures.
2. Complete all electrical connections.
3. Complete all sensor connections.
4. Set up the controller and all settings via the web-app.
Apply All Safety Measures
1. Switch offcircuit breaker of geyser at the main distribution board (DB).
2. Switch offthe isolator switch in the roof. The isolator disconnects the live and
neutral so that - should someone accidentally switch on the main supply or the
circuit breaker fails - there will be no power at the geyser.
3. Test with a multimeter that there is no current on the wires.
Electrical Installation Instructions
Included below is a schematic diagram of how the different components of the system
should be installed, where after step-by-step instructions are given.

Power Installation
Step-by-step instructions are included below, followed by a photo of the Geasy PCB.
1. Remove the mains supply from the geyser's thermostat.
2.Install a new length of “twin and earth”cable between the Geasy controller and
the geysers thermostat, for the electrical supply of the geyser’s heating element.
a) Connect the earth wire to the right-hand side terminal for the geyser’s supply,
labelled ‘E’
Note: The Geyser must be earthed.
b) Connect the neutral wire to the right-hand side terminal labelled ‘N’.
c) Connect the live wire to the right-hand side terminal labelled ’L-out’.
d) Now, connect the earth, neutral and live wires to the appropriate terminals
on the geyser’s thermostat.
3. Use the electrical supply from the isolation switch to power the controller:
a) Connect the earth wire to the left most terminal, labelled ‘E’
Note: The Geyser must be earthed.
b) Connect the neutral wire to the terminal located second from left and labelled
‘N’.
c) Connect the live wire to the terminal located third from left and labelled ’L’.

Operation
Product Description
Geasy is a smart geyser controller that enables the management of an electric water
heater (EWH), commonly known as a geyser, through an online platform. Geasy has
internet connectivity whereby it sends information and receives instructions from the
BridgIoT (RF) (Pty) Ltd web-app. The Geasy is retrofitted to an existing EWH and offers
the following functionality:
1. Switching the EWH ON and OFF by switching the supply to the heating element.
Control through:
a) scheduling or;
b) real-time temperature control.
2. Measure power consumption.
3.Internet connectivity through a cellular connection.
4. Measuring up to 3temperatures:
a) water outlet temperature and/or;
b) water inlet temperature and/or;
c) ambient temperature.
5. Optional: Detect the presence of water in the drip tray.
Safety
Do not interfere with the device. If you have to open the enclosure of the device, for
whatever reason, only do so after switching offthe power supply at the isolation switch.
Only switch on the isolation switch after the enclosure has been closed.
User Responsibilities
The user may not use the device's sim card (if supplied by BridgIoT (RF) (Pty) Ltd) for
any other purposes if the sim card was provided with the device. The sim card must,
therefore, remain within the device. The user must immediately notify BridgIoT (RF)
(Pty) Ltd, or their service provider, if the sim card is lost/stolen.

Device Status
There are two LED lights indicating the status of the device. The number of times each
LED flashes per cycle indicates a state. These definitions are subject to change.
The green LED indicates the connectivity status of the device.
Single Flash Fully connected
Two flashes Partially connected
Three flashes Not connected
The red LED can indicate the state of the EWH.
Single Flash EWH supply is switched off(i.e, not heating)
Two flashes EWH supply is on, but not drawing power (i.e, not heating)
Three flashes EWH supply is on and drawing power (i.e, heating)
If your device loses connectivity to the online platform, for whatever reason, it will go
into a default state. The default state is an “Always on”state with a temperature set point
of 55 °C. The quality of the connectivity is dependent on the cellular service provider
(CSP) used for the device. If your device is experiencing consistent connectivity issues, it
might be necessary to change CSP.
To reset your device, switch offthe supply to the device by switching the EWH circuit
breaker offat the distribution board.
The only way of overriding the device is for an installer to electrically bypass the device.
Temperature Control & Scheduling
Heating scheduling is performed via the cloud, no scheduling information is stored
locally and thus your Geasy requires continuous internet connectivity.
Geasy can perform temperature control of the EWH based on the estimated internal
temperature. Geasy does not replace your standard thermostat, and can therefore not
heat the water higher than the thermostat is set at. This ensures the safe operation of
the EWH and prevents overheating.
Burst/leak Detection
Depending on what components are installed, the device can provide burst/leak
detection and mitigation. The drip detection sensor in the drip tray can detect the
presence of water. Upon detection of water, the online platform then notifies the user
of a potential leak or burst. Note that your Geasy must have power and an internet
connection for the notification to be sent.
To open the water supply and turn the EWH on again, the device typically has to be reset.
Page 10 of 17

If there is still water present in the drip tray, the device will trigger a burst event again.
It is therefore required that the user ensures that there is no burst or leak and removes
the water from the drip tray before resetting the device.
User Interface
The user can manage their device via the BridgIoT (RF) (Pty) Ltd online web-app, found
at app.bridgiot.co.za. Please sign up on this web interface, by clicking the “Sign up”link
on the landing page as shown below, in order to access your device data and settings.
The user interface will typically include the following functionality (although functionality
may be added (or subtracted) from time to time):
1. Switching the EWH heating ON and OFF.
2. Schedule heating of the EWH.
3. Power consumption.

will take you to a screen similar to the one below where a schedule of the current heating
times and temperatures are given. The minimum scheduling temperature has been
limited to 51 °C in order to prevent legionella growth in the geyser and piping.
From here any number of schedules can be create by any of the users associated with
this geyser controller and all of them will be visible here.
For the more data driven individuals, there is an analytics view, where the heating and
water usage data (if water meters have been installed) is available as time series data.
This view helps to identify usage patters as well as quantities of power and water usage
over different time periods1.
