Parallel pumps- both the central heating and the domestic hot water installations work.
•
The burner and the pumps work as in DHW priority. The only difference is that the central
heating circulation pump is allowed to work together with the DHW pump.
Summer Mode – the boiler works only to heat up the water heater. The difference between
•
this mode and DHW Priority is that the burner turns on only if the water heater needs to be
heated. When the water heater reaches the set temperature (WH set temp) the burner turns
off. This mode does not control the central heating installation.
•
Manual Feeding – Manual control of the fuel auger motor or the circulation pumps. This function
is useful to fill up the auger motor when it's empty, to measure its capacity of pellet feeding for
calibration purposes, to test the pumps or to fill up the installations with fluid.
Timer for
fuel auger operation
The maximum time for manual control is about 6 minutes. After that the controller turn off outputs
and go to the previous screen. This mode can be used for calibrating the fuel auger motor, by first
filling the whole auger and then turn it on, to work for the desired exact period. Can be for
example 3 minutes, during witch time the pellets fall into a large enough container. Then the
weight of the pellets that have been collected must be measured and the number multiplied by 20.
This will give us how many kilograms of pellets fall per hour from the auger.
