1. Overview
Thank you for hoosing immerSUN. This intelligent devi e is a sensible and pra ti al addition to your PV
or Wind mi rogeneration system.
Water is heated via your existing immersion heater, using surplus power that would otherwise have been
exported to the grid.
Please read and follow this guide to ensure many years of trouble-free operation and savings!
Key features
•Heats water from your PV system or Wind Turbine
•Effe tively adjusts power levels to the immersion heater, keeping the exported
power at virtually zero
•The onsumer no longer needs to be at home to use the free ele tri ity,
whatever the weather
•No need to hange the immersion heater
•Suitable for all ele tri al mi rogeneration systems
•Built-in hot water boost timer
•Manual hot water boost fun tion
•Ba k-lit LCD display shows energy saved, output power and operating mode
•Dual immersion heater ontrol option
•Internal multi-fun tion relay in-addition to the modulated power output
•Up to 4 devi es an be daisy- hained for master / slave operation

3. Installation
3.1 Mounting
Often, the most suitable lo ation for the immerSUN is near to the onsumer unit. Usually all the
onne tions required are available here.
The following should be onsidered when de iding upon the most suitable lo ation:
•Close to the main in oming mains ele tri al supply of the property
•A ess to immersion heater supply able (this is usually at the onsumer unit)
•A ess to suitable supply via 16A MCB or 13A fused outlet
•User a ess to immerSUN ontrols and visibility of LCD s reen
•Adequate ventilation – keeps vents lear and provide airflow around the unit
•Cable a ess point – through the rear or bottom of the unit
Use the 3 s rews and wall plugs provided to mount the immerSUN at the hosen lo ation.
Remove LCD protective cover after mounting the unit
DO NOT BLOCK VENTS! The en losure may get hot, always keep vents lear of obstru tion and allow
suffi ient learan e from walls, eilings and other obje ts. Observe minimum learan es as shown below.

3.2 Ele tri al Conne tions
Electrical connections should be made only by a competent person Do not attempt to install this
unit if you are not a qualified or an experienced electrician Installation may involve alterations to
fixed wiring and opening the consumer unit, there is risk of death by electrocution
Choose the most suitable able entry points (rear or bottom) and make the ele tri al onne tions to the
unit a ording to the appropriate wiring diagram (see se tion 3.4). Use the blanking plugs provided for
unused able entry points.
Alternative loads
In some ases it may be desired to ontrol the power to a load other than an immersion heater. The load
MUST be a simple resistive load, e.g. an ele tri towel radiator, storage heater et .
The load must not ex eed 3.2kW and must not in lude digital or analogue timers, as they may be
damaged by the proportional output ontrol of the immerSUN.
IMPORTANT!
Be sure to fully tighten terminals, he king the ables are se urely lamped by the terminals and the ord
grips. Failure to ensure good onne tion ould result in fire or permanent damage to the unit.
NOTE: The s rew terminals are 'rising lamp' type.

3.3 Clamp Installation
Corre t positioning of the urrent sensor lamp is vital to the operation and effi ien y of the immerSUN.
In orre t installation may result in in reased ele tri al osts to the user.
The lamp should be lo ated at the main incoming grid supply to the building. This will be the supply
from the main ele tri meter (NOT the PV generation meter). Close the lamp around one of the ables
(Live or Neutral) from the meter, this an be at the meter lo ation or inside the onsumer unit.
IMPORTANT! Ensure the lamp is se urely losed around the able.
Conne t the lamp wire to the CT terminals inside the immerSUN. Don't worry about polarity as the
immerSUN will figure it out during setup.
PV connected via Henley Block
If the PV system is onne ted via a 'Henley Blo k' then the lamp should be installed on the grid side of
the blo k, i.e. between the meter and Henley blo k.
More than one consumer unit
Where there is more than one onsumer unit, the lamp should be installed at the primary in oming
supply (i.e. before it splits).
Three phase supply
One immerSUN will only work on one of the phases, the lamp MUST be installed on the SAME PHASE
that is wired to the immerSUN, the inverter MUST be on the SAME PHASE also.
If the inverter is 3-phase, then the immerSUN will only 'see' the import/export on that phase, therefore not
all of the export power an be utilised.
Extending the clamp cable
The lamp wire an be extended if required, however due to the small signal from the lamp, twisted-pair
able should be used to help eliminate possible interferen e. The maximum able length is 50m. Most
types of twisted-pair able an be used, e.g. Beldon able, Cat.5, telephone able et .
8

3.4 Wiring Diagrams
Single heater wiring
Most installations will be a single immerSUN onne ted to a single heater. This is shown in the diagram
below.
Alternative wiring method
If the immerSUN is lo ated lose to the onsumer unit, it may be simpler to use the alternative wiring
option using 4- ore able or singles. As the Earth and Neutral terminals are ea h ommon, the alternative
option shows that the heater earth and neutral need not be dire tly onne ted the the immerSUN. The
alternative wiring method an also be used for all of the additional wiring options.
Using the multifunction relay
When wiring one of the options involving the relay onta ts, the relay fun tion must be sele ted. This is
done via the Relay Fun tion option in the Installer Menu. See se tion 4.3. The relay an be set to perform
only one of the fun tions.
Linking several immerSUN units (Cascading)
Up to four immerSUN units an be linked together. This allows up to 12kW (3kW for ea h immerSUN) of
surplus power to be utilised on one phase. This is known as Cas ading as the first immerSUN will
onsume the first available 3kW, the se ond unit in the hain will then onsume the next available 3kW
and so on. When using as ade mode, ea h immerSUN must have its own 3kW (maximum) load.
The immerSUNs should be linked in a 'daisy- hain' fashion with twisted-pair signal able using the
COMMS terminals A and B. Cas ade mode needs to be sele ted in the Installer Menu. See se tion 4.3
For simple single heater ontrol, relay onne tions not required, omms onne tions (A&B) are used only when several immerSUN
devi es are to be linked. (Also see Alternative Mains Wiring diagram).

Rather than using the immersion heater to boost hot water, an external heat sour e e.g. a boiler an be used by making use of the
multi-fun tion relay wired to the boiler hot water ontrols.
I t may be desirable to use a de-stratifi ation pump to mix the ooler water at the bottom of the ylinder with the hotter water at the
top, this allows a top mounted immersion heater to heat all of the water in the ylinder.

3.5 Using the immerSUN with a dual-rate ele tri al supply
There are 2 ommon ways that a dual-rate ele tri al supply an be onfigured...
1 A single dual-rate meter feeding the whole house
This is the most ommon onfiguration.
•The immerSUN should be wired as normal. See wiring diagrams in se tion 3.4
•The immerSUN's Timed Boost should be set to operate at off-peak times.
•Remove any timers that are installed on the immersion heater ir uit.
2 Two meters supplying two consumer units
With this onfiguration there is a separate timed off-peak supply.
•Wire the immerSUN as shown in the diagram below.
•Set the Relay Fun tion to Water Boost and then set the Timed Boost to operate at off-peak
times.
•Remove any timers that are installed on the immersion heater ir uit.
•Label the immersion heater with a “Dual Supply” warning label.
•Please Note: It will not be possible to Boost outside of off-peak times.

4. Installer Settings
On e the unit is mounted and wired, the installer will need to set parameters as required for the parti ular
installation. Before applying power to the unit the DIP swit hes will need to be set.
4.1 DIP Swit h Settings
The default position of the DIP swit hes, is all four set to ON. For the majority of installations this will be
the orre t setting. However if several immerSUN devi es are being as aded, then the DIP swit hes will
need to be set a ordingly, see table below.
