System 2
System 2 is a system structure with solar heat connected to an external heat
source tank (EHS tank) and an extra buffer tank (CTC VT 80 for example).
The system allows for a larger solar collector surface since it carries a greater
volume of water.
Charging conditions
• Charging starts when B31 is 7°C warmer than B42.
• Buffer tank without coil:
• Charging stops when there is a difference of 3°C between B31/B30 or
when the charge temperature is reached.
• Buffer tank with coil:
• For a tank with a solar coil, the charging stops instead when B31 is
3°C warmer than B42.
• Charging of the EHS tank compares sensor B41 to sensor B47.
The buffer tank (02) may also have a solar coil; this means that the heat
exchanger (F2), pump (G32) or non-return valve (Y11) is not required.
System 3
System 3 is a system structure with an extra volume called 03; this can be a
large extra tank or a pool. The greater the water volume, the larger the solar
collector surface required.
System 3 is solar heat connected to an external heat source tank (EHS-
tank) and an extra buffer tank. The system allows for a larger solar collector
surface since it carries a greater volume of water.
Charging conditions
• Charging starts when B31 is 7°C warmer than B42 or B47.
• Charging stops when there is a difference of 3°C between B31/B30 or
when the charge temperature is reached.
