Introducing the immerSUN
Thank you for choosing immerSUN - You have made an excellent choice!
The immerSUN is an automatic power controller for heaters. It tracks available surplus
power from a grid-tied 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 utilised.
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 sophisticated than any
similar product on the market. TruSine™ technology ensures trouble free operation with
all inverters and compatibility with all import/export energy monitors.
Feature Set
●
Tracks surplus power and diverts this energy to the load
●
trusine™ technology for fast and smooth automatic power adjustment

Savings Today
Savings shown alternates between
kWh and financial savings in the set currency.
Current Heater
The symbol for the heater
being heated is shown along
with the heater number.
Heater Power
The amount of power
currently being sent to the
heater.
Grid Power
The power either, being
imported or exported.
Import or export is shown by
the direction of the arrow
between the Grid and House
symbols.
Date & Time
The current date, day of week
and time.
Main Screen
The main screen shows the status of the immerSUN, the imported or exported power, the
date and time 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
direction 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 financially in the chosen currency. For the
financial savings to be correct, the user must keep the tariff up to date. The Set Tariff
option in the Main Menu allows the user to set the current tariff, this should be set to
reflect the kWh cost for the fossil fuel normally used to heat the heater.

Boost (Manual)
A heater can be 'boosted' to full power for a short period regardless of the amount of
available export power, this function is called Manual Boost and is activated 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
any time.
7
Boost (Timed)
Important points
●
Up to six different boost times can be entered.
●
Each week day can be individually selected for each boost time.
●
Only ONE heater can be boosted at any one time.
●
If any boost times overlap, the latest timed boost will take presidence.
●
For boost times crossing midnight, two time slots will need to be used.
The immerSUN can be programmed to 'boost' the heating for each heater at certain
times. 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 times.
The Boost Times can be accessed from the Main Menu.
Once in the BOOST TIMES screen, use the and buttons to select the boost time you
wish to change, then press. You can now edit the boost times, use the and
buttons to change the start time, end time, days of the week and heater number for the
boost, (press the button to move to next section). Press the button to exit edit
mode.

Set Tariff
The tariff should be set to that
shown on your utility bill. You will
need to adjust the tariff from time
to time as the tariff changes. The
tariff should be that of the fossil
fuel you normally use to heat the
appliance.
The New tariff will take effect
From the date entered, which can
be a past or future date, meaning
the New tariff does not need to
be set on the day it changes.
Set Heater Priority
If two or three heaters are
connected, the heating sequence
can be selected.
The higher priority heater will be
heated until the thermostat
opens, then the next priority
heater will start to be heated and
so on. When heating a lower
priority heater, the unit will switch
back to the higher priority heater
periodically, this period is set by
Check Period in the Advanced
Settings menu.
If the heating priority is set to
Equal, then each heater will be
heated in-turn for the time set by
the Check Period in the Advanced
Settings menu.

What Does It Do?
This is an external input which can be used to trigger a boost or enable/disable heater
outputs.
The External Boost input is the 2-terminal connector labelled EX BST. Any AC voltage from
24V to 240V present on these terminals will be recognised by the immerSUN.

Heater Thermostat
The EX BST input will act as a
