Top sensor – this option is used to select the sensor which will serve as the top sensor. It should be placed in the
upper part of the tank.
Bottom sensor - this option is used to select the sensor which will serve as the bottom sensor. It should be
placed in the lower part of the tank.
8.11. RELAYS
This algorithm is used to control the device which is to be enabled at the same time as selected devices in the heating
system.
Operation mode function enables the user to decide when the contact will be activated:
All - The contact is enabled when all relays are
active.
Any - The contact is enabled when any of the relays
in active.
None - The contact is enabled, when no relay is
active.
8.12. ADDITIONAL HEATING SOURCE
The additional heat source will be enabled when the temperature read by the sensor drops below the activation
temperature. It will operate until the temperature exceeds the threshold value by hysteresis.
Additional factor influencing additional heat source operation may be a room regulator. If any of them is selected , the
additional heat source will be enabled if the pre-set temperature of the regulator has not been reached, regardless of
other circumstances.
Pump activation threshold – this function is used to set pump activation/deactivation threshold. Additional heat
source will be enabled when the temperature of the selected sensor drops below the threshold value.
