Diagram 2 (buffer tank sensor)
Diagram 2 can be used in a system where there is a buffer tank that operates the heating system and, if pre-set, also DHW produc-
tion. In this system, the thermo-stove is directly connected to the buffer tank.
In this type of circuit, room temperature is managed by a control unit (not supplied) that controls the buffer tank and any zone valves.
The buffer tank temperature is controlled by the thermo-stove through a sensor.
The thermo-stove operates at maximum power to reach the set buffer tank temperature. When it is reached, the stove enters ECO
STOP mode and is automatically restarted if the buffer tank temperature falls below this value. The advantage of using a buffer tank
is that it regulates the operation of the thermo-stove. The buffer tank can be connected to other heat production units, such as solar
panels and/or gas boiler.
