SERVICE PARAMETERS
Setting range
In a system with two or more storage
tanks, you set the order of loading
priority.
If the system is loading (for a setted
time) the non priority storage tank,
the operation is temporarily stopped.
This way controller (after setted pause
interval S2.6) is able to check the
differential condition for the priority
storage tank and switch to the priority
storage tank loading.
This is the time in which controller
waits for rise of collector temperature,
which needs to be 2 K or higher. If the
rise is sufficient, controller waits for
the differential condition for loading
the priority storage tank to be fulfilled.
If temperature rise isn't sufficient, the
controller starts to load first non-
priority storage tank with fulfilled
differential condition.
Means that storage tank 1, if heated
above the set-point temperature, can
be forcibly cooled down to the set-
point temperature. Cooling is achieved
by means of collectors and pipe
installation.
Means that storage tank 2, if heated
above the set-point temperature, can
be forcibly cooled down to the set-
point temperature. Cooling is achieved
by means of collectors and pipe
installation.
Means that storage tank 3, if heated
above the set-point temperature, can
be forcibly cooled down to the set-
point temperature. Cooling is achieved
by means of collectors and pipe
installation.
We define whether storage tank
1 should be loaded (by means of
collectors) only to the set point
temperature.
