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.
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.
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.
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.
Boost (Timed) 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 Multifunction Relay is a relay that can be used for many different purposes. The operation is controlled by the immerSUN and will operate when certain conditions are met, these conditions can be user defined. The relay can be used to control pumps, send signals to the boiler and switch on/off appliances etc.

(linking units) immerLINK™ is a wireless network used by immerSUN devices. Up to 5 immerSUN units can be 'linked' together by using immerLINK™. Linking several units enables more export power to be consumed, with each device being able to control a 3kW load, up to 15kW of would-be exported power can be utilised.

Underfloor Heating – Option 1 Electric underfloor heating (UFH) can usually be used with the immerSUN. This wiring diagram assumes that the UFH is to be used alongside another heater (most likely an immersion heater).

UFH system can be used as the only heater by wiring to the Heater 1 output. The UFH thermostat is wired solely to the immerSUN, power is taken from the immerSUN supply and External Boost input is used to sense the UFH thermostat state. The UFH mat is connected directly to Heater 2 output.

Dual Tariff Wiring – Single Meter It is simple to wire the immerSUN to handle dual rate tariffs when there is only one supply meter. The External Boost input can be used to detect when the economy rate electricity is available and automatically boost the heater output.

If there are two meters at the property, for dual tariff metering, it is necessary to make sure that power is drawn from the correct meter. The immerSUN must be powered from a 24-hour supply and the heater must be connected directly to the immerSUN, however, during the economy tariff times, the heater needs to draw power from the economy tariff meter.
