2.3. Sequence Of Operation
The hot water storage tanks used in this heating system must be equipped with the two provided
temperature sensors, or other sensors meeting requirements for a NTC 10k temperature sensor.
The BT2 sensor (hot side probe) is located in the top of the last storage tank in the series, near the
supply outlet. The (BT1) sensor (cold side probe) is placed in the bottom of the first storage, near
cold return water connection.
The optional BT3 sensor is located on the outlet of the external heat exchanger (see
dedicated section) and is needed to modulate the inverter circulation pump placed
between the heat exchanger and the storage tanks. Installation of BT1, BT2, and BT3 probes
must be done by the installer prior to operation.
Note that the tanks must necessarily be hydraulically connected in series as shown
below, not in parallel.
When the temperature probe BT1 reaches the value "Set point unit ON", (set point (ST03) minus
differential (ST04)), the unit will be turned on. The unit will continue to heat the water to the
set temperature as long as the temperature BT1 remains below the
“Set point unit OFF” value
(ST03). Once BT1 reaches "Set point unit OFF" the unit will be turned off.
