Explanation
Setting to manage a pump and a sensor for domestic hot water
Setting to manage a pump, a sensor and to use the valve connector to control a relay for
the electric resistance of the tank. When switching to summer mode the tank automatical­
ly switches to electric.
Setting to create a time schedule on the pump connectors.
Setting to manage a pump, heats 365 days 24/24, no stop in summer, priority on all cir­
cuits. The boiler will remove all protections to produce maximum power in a minimum of
time
Setting to manage domestic hot water with 2 sensors, a tank top sensor (Tsyst 1 or 2)
triggers the load and the bottom sensor of the tank (Tdhw) triggers the stop of the charge.
Setting to manage domestic hot water for boilers with internal tank.
There are three options for the 0-10 Volt input control of the SCB-10 print:
The 0-10 Volt input control can be changed with parameter EP014
The temperature setpoints can be changed with parameter EP030
(minimum) and parameter EP031 (maximum).
The power setpoints can be changed with parameter EP032 (minimum)
and parameter EP033 (maximum).
The voltage setpoints can be changed with parameter EP034 (minimum)
and parameter EP035 (maximum).

The 0–10 V signal controls the boiler supply temperature. This control

modulates on the basis of flow temperature. The output varies between
the minimum and maximum value on the basis of the flow temperature set
point calculated by the controller.

3.2.2
The 0 - 10 V signal controls the boiler output. This control modulates on
the basis of the heat output. The minimum output is linked to the boiler's
modulation depth. The output varies between the minimum and maximum
value on the basis of the value defined by the controller.
Disable the input function.
The input is temperature based.
The input is heat output based.
