Fault Signal
The relay will DEACTIVATE if
a fault is detected. It will
remain deactivated until the
fault is cleared or the
immerSUN is restarted.
When External Boost
The relay will activate whenever
there is an AC voltage at the EX BST
input connector.
In this mode the relay can also be
controlled with the
Manual
and
Timed Boost
options.
Export Threshold
The relay will activate when a set
export power
Threshold
is reached.
The relay will remain activated a set
minimum
ON
Period.
After this
period the relay will deactivate,
unless the export threshold still
exceeds the set level. If the export
has fallen below the threshold after
the
ON Period
, the relay will
immediately deactivate and will
remain so for the set
OFF Period.
This function operates independent
to the heater outputs.
When the
Priority
is set to
HIGH
the
relay will activate when the surplus
power exceeds the threshold
set. i.e. it will include the already
diverted power when waiting for
the threshold to be exceeded.
With the priority set to
LOW
, relay
will activate when the exported
power is greater than the set
threshold.
In this mode the relay can also be
controlled with the
Manual
and
Timed Boost
options.
What Does It Do?
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.
Multifunction Relay Contacts
NO – Normally Open
C – Common

Heater
The relay is used to switch heater 2
output between two different
heater loads, therefore enabling 3
heaters to be sequentially
controlled.
When this option is set
Heater 3
will be available on some menu
options.
