- The domestic hot water priority function whereby when
there is demand for domestic hot water, the master
board can also serve the high or low temperature cir-
cuit.
- The frost protection function, also active in standby,
which starts the pump in the high temperature circuit
and the loop pump if the temperature in the manifold
falls below 5°C.
If the outside probe is fitted, the pumps start if the out-
side temperature falls below 3°C.
If after 10 minutes the temperature in the manifold is
less than 5°C, one burner starts at maximum output,
until the temperature in the manifold reaches 20°C.
If after 10 minutes the temperature in the manifold
exceeds 5°C but the outside temperature is less than
3°C, the pumps stay on until the outside temperature
exceeds this value.
- The dispersion function: the pumps in the high and low
temperature circuits remain on for 5 minutes after the
last burner has shut down. There is a 6 minute delay
from when the burner shuts down before closing the
two-way valve. When the last burner has shut down,
the valve closes only when there is no demand from the
room thermostat.
- The cascading function: to manage the output delive-
red by the system, the minimum and maximum number
of burners started can be selected.
- The burner on/off control function: in both cascading
modes there is a function that limits the ignition and
shutdown of the burners in the event of low heating
requirement.
