The relay will be ON. This function is
useful for testing circuits connected
to the relay contacts.
When Heating
The relay will operate whenever the
selected heater(s) are being heated.
Include Hot: If ticked the relay will
remain closed when the heater has
reached maximum temperature and
it's thermostat is open.
Include Boost: If ticked the relay will
also operate during timed or manual
boost.
When Boosting
The relay will operate whenever the
selected heater(s) are being boosted,
either with manual boost or timed
boost.
Boiler Boost
The relay will operate whenever
a manual boost or timed boost is
activated for the selected heater(s).
The heater will NOT be boosted
by the immerSUN but will heat as
normal. Instead an auxiliary boiler
will be called to boost.
Destrat Pump
Once the heater thermostat opens,
the relay will operate (to run a
destratification pump). The pump
will run for the duration set by the
Check Period option in the Advanced
Settings Menu.
