Underfloor Heating – Option 2
Electric underfloor heating (UFH) can usually be used with the
immerSUN. This wiring diagram assumes that the UFH is to be used
alongside an other heater (most likely an immersion heater). However
the 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.
The External Boost input is used in 'thermostat' mode so that the Heater
2 output is active only when the UFH thermostat is calling for heat.

Tips & Ideas
●
Smaller loads can be connected in parallel as long the maximum
load is not exceeded.
●
The immerSUN has built-in timers that can replace any timers that
have been removed.
●
The
Multifunction Relay
is free to use to control other devices.
