V.h) Installation Options
This submenu is visible only in the case of activating the installation scheme number: 5, 10 or 11.
V.h.1) Reheating Activation Delta
This option is only active in the case of setting the installation scheme number: 5.
This installation model has an additional circulation reheating the tank using the CH Boiler. If the
tank's temperature is lower than the tank's set temperature, at least by the value of the set activation
delta (this is the difference between the tank's set temperature and the tank's current temperature),
the auxiliary pump (from the boiler) is activated to reheat the Accumulation Tank (provided that the
boiler's temperature is higher than the tank's temperature). This setting is active only in hours defined
by the user ("From/To").
V.h.2) From Hour... to Hour...
This option is only active in the case of setting the installation scheme number: 5.
These settings define in which hours ("From/To") the circulation from the CH Boiler reheating the
Accumulation Tank is active (see the previous point).
V.h.3) Energy Release
This option is only active in the case of setting the installation scheme number: 5.
Activating scheme 5 enables the energy release (e.g. to the CH installation) above the tank's set
threshold temperature.
V.h.4) Energy Release Threshold
This option is only active in the case of setting the installation scheme number: 5 and 11.
This parameter is used to adjust the threshold tank temperature at which the valve will switch to
reheating the boiler's return.
V.h.5) Release Hysteresis
This option is only active in the case of setting the installation scheme number: 5 and 11.
When the release threshold temperature is reached, the valve switches the power supply to the
boiler's return circulation. The valve is switched again after the tank cools down by the value of the
release hysteresis.
V.h.6) Solar Pump Release
This option is only active in the case of setting the installation scheme number: 5, 11.
After activating schemes 5 or 11, this installation makes it possible to deactivate the Solar Pump's
operation, e.g. to cool down the tank using the Auxiliary Pump.
V.h.7) Reheating Deactivation
This option is only active in the case of setting the installation scheme number: 10.
The tank in scheme 10 is reheated with a double function furnace. The function reheating
deactivation applies to the threshold temperature to which the tank is to be reheated – if the tank's
temperature exceeds this value, reheating with the double function furnace is deactivated (valve
switched).
V.h.8) Activation Delta (return)
This option is only active in the case of setting the installation scheme number: 11.
This parameter determines the maximum difference between the tank temperature and the boiler
return circulation temperature at which the valve switches to reheating the boiler's return.
