Introducing the immerSUN™
Thank you for choosing immerSUN - You have made an excellent choice!
The immerSUN is a Solar PV Self-Consumpon Controller for heaters. It tracks available surplus
power from a grid-ed PV or Wind turbine system and varies the power to the heater to match
the surplus power, therefore ensuring all of the green energy is fully ulised.
trusine™ Power Control Technology
The immerSUN uses TruSine™ power control technology. This means that the voltage is
very smoothly adjusted to alter the power to the heater. The power going to the load is
a non-distorted true sine wave, only the voltage is altered.
This control technology is unique to the immerSUN and is more sophiscated than any similar
product on the market. TruSine™ technology ensures trouble free operaon with all inverters
and compability with all import/export energy monitors.
Feature Set
● Tracks surplus power and diverts this energy to the load
● trusine™ technology for fast and smooth automac power adjustment
● Works with many microgeneraon systems including PV, Wind and Hydro systems
● Clear graphical backlit LCD display
● Indicates current import/export power levels as well as diverted power to the heater
● Savings are accurately reported for the day, month, year as well as the total since installaon
● Savings can be displayed in several currencies as well as kWhs
● No need to change immersion heater
● Works with many types of heater including storage, panel and underoor
● One immerSUN can control up to 3 heaters sequenally
● Only one current sensor for ease of installaon with the opon of a wireless sensor
● Built-in 7-day programmable boost mer
● Manual boost funcon for both heater outputs
● Integral mul-funcon relay to provide addional funcons such as: Economy-7
control, cylinder de-stracaon pump control and export power threshold detect
● Up to 5 immerSUN’s can be linked together for larger systems
● Smart, sturdy metal enclosure designed with the installer in-mind
● Fully short circuit protected in case of load fault
● Over load protecon
● So starng to avoid power surges
● Smart meter compable

Main Screen
The main screen shows the status of the immerSUN, the imported or exported power, the
date and me and the savings made today.
The house in the centre of the screen will be ‘happy’ if no power is being imported, otherwise
a straight face will be displayed. Arrows either side of the house show the direcon of power.
From this screen the Menu can be accessed, a manual Boost can be triggered and there is a
short-cut to the Savings data.

Savings
Savings that have been made by immerSUN are stored in permanent memory. The savings
can be shown for Today, this Week, this Month and this Year as well as the Total since the
immerSUN has been installed. The savings can be displayed as a list or in a graph.
The savings are shown in kWh as well as nancially in the chosen currency. For the nancial
savings to be correct, the user must keep the tari up to date. The Set Tari opon in the
Main Menu allows the user to set the current tari, this should be set to reect the kWh
cost for the fossil fuel normally used to heat the heater.

Boost (Manual)
A heater can be ‘boosted’ to fuII power for a short period regardless of the amount of available
export power, this funcon is called Manual Boost and is acvated from the main screen. Once
the boost starts, the remaining boost period will be displayed, this will start at 1 hour but can
be adjusted during the boost. A manual boost can be cancelled at anyme.

Boost (Timed)
The immerSUN can be programmed to ‘boost’ the heang for each heater at certain mes.
Boost means that the heater will be at full power regardless of the amount of available export
power. This means that power may be drawn from the mains grid supply during boost mes.
The Boost Times can be accessed from the Main Menu.
Once in the BOOST TIMES screen, use the and buons to select the boost me you
wish to change, then press . You can now edit the boost mes, use the and buons
to change the start me, end me, days of the week and heater number for the boost,
(press the buon to move to next secon). Press the buon to exit edit mode.
Special heater types
There are two special heater types; T and B. These will only be available if the Mul Funcon
Relay is set to Export Threshold or Boiler Boost and wired correctly.
T: Export Threshold boost, the appliance will be acvated for the boost period.
B: Boiler boost, the boiler will be acvated for the boost period.
Important points
● Up to six dierent boost mes can be entered.
● Each week day can be individually selected for each boost me.
● Only ONE heater can be boosted at any one me.
● If any boost mes overlap, the latest med boost will take presidence.
● For boost mes crossing midnight, two me slots will need to be used.
