reheated (if the conditions for switching to the first circulation are still not met).
V.e.12) Deactivation Delta of Pump 2
Option active only in the case of setting the installation scheme number: 3, 7, 8, 12 and 14.
This function determines the difference between the collector temperature and tank 2
temperature when the pump is deactivated (so as to avoid cooling down the tank).
V.e.13) Activation Delta of Pump 2
Option active only in the case of setting the installation scheme number: 3, 7, 8, 12 and 14.
This function determines the difference between the collector temperature and tank 2
temperature when the pump begins to operate (this is the pump's activation threshold value).
V.f) Peripherals
The user may connect and configure the settings of an additional device. If there is no additional device,
the user should select the position
NO (deactivate). Additional available devices and examples of
connections supporting all available installation schemes are presented below.
In the case of using schemes 12 or 14, it is not possible to connect an additional device – the function
is inactive.
V.f.1) Circulation Pump
After selecting this device, the user should adjust the pump's periodical Operation Time and Stoppage
Time during its activity. Then, the user should define in which hours the pump will be active, with the
use of the " From " and " To " functions. Entering the same times (" From – To" ) will result in the device
being active throughout the whole day.
V.f.2) Firing up the PLT Boiler (pellet)
This option is used to adjust the voltage-free signal to fire up the pellet boiler. The user sets the
Activation Delta , namely the difference between the tank's set temperature and the tank's current
temperature which leads to the controller sending a signal to fire up the boiler. Then, the user selects
the time interval in which this function will be active (using the function "
From " and " To ")
