PERIPHERALS

The user may connect and configure the settings of an additional device. If there is no additional device, the user should
select NONE (deactivate). Additional devices to choose from and examples of connections supporting all available
installation schemes are presented below. In the case of schemes 12 and 14 it is not possible to connect an additional
device - the function is unavailable.
•
Circulating pump - Once this device is selected, the user should adjust operation time and pause time of the
pump during its activity. Next, the user should define the hours of pump operation using From hour and Through
hour functions. Entering the same times (from – through) will result in the device being active throughout the
whole day.
•
PLT (pellet) boiler fire-up - This option is used to set up the voltage-free signal to fire up the pellet boiler. The
user defines activation delta - the difference between the pre-set tank temperature and the current tank
temperature at which controller sends a signal to fire up the boiler. Next, the user selects the time period
throughout which this function will be active (with the use of from hour and through hour parameters).
