Recharging
Storage Tanks
In the case of layout plans with several storage tanks it is very easy
to implement storage tank recharging with the help of a differential
thermostat.
To enable this recharging function you need only one of the four
differential thermostat functions (Chapter 5.2), two available inputs
and one available output (called Tx, Ty and Rx in the adjacent
diagram).
Function:
If storage tank X has been discharged to such an extent that the
differential temperature between storage tank X (upper part) and
storage tank Y (lower part) exceeds a set value, the circulating pump
Rx is activated and heat is therefore recharged from storage tank Y
to X. Depending on the type of individual storage tanks this
recharging can be done directly or via a heat exchanger.
Implementation: Open the menu item 'Settings' -> 'Service' -> 'Functions' -> 'diff. thermostats' and
activate an available diff. thermostat (
--2sec OK-->
:
). Then under Settings enter the desired
switch-on and switch-off differential and also the terminal positions of the temperature sensors (Tx and
Ty) and the recharging pump (Rx).
With a corresponding entry of min.temp input.W and max.temp input C, excessive cooling of storage
tank Y or overheating of storage tank X can be prevented. In the event of going above or below one of
these temperature values, the function of the storage tank recharging is deactivated again.
