Auxiliary stage with fan coil
In some heating / cooling system, an auxiliary fan coil system which operates on air volumes is paired with an
high inertial system (such as floor radiant panels): EK-ET2-TP Multisensor controller can be easily configured
for this kind of application.

As for the configuration of the auxiliary stage, you can apply the same rules already expressed in the ON/OFF
and continuous fan coil control paragraph. Particularly relevant here is the auxiliary stage intervention offset,
ΔT
Offset
, which matches the parameter
Setpoint difference
in
Heating and/or cooling
folder. By configuring this
parameter (which can be different between heating and cooling if command communication objects are
separated) to 0 K, the radiant panel and the fan coil work as two heating and/or cooling devices in parallel.
Otherwise, if
Setpoint difference
> 0 K
,
the fan coil intervenes very quickly in the first tuning stages and leaves
to the radiant panel the job of reaching the desired temperature.
