CTC EcoLogic Pro/Family
For the installer
The coniguration of EcoLogic systems 2 and 3 differ in terms of the location
of the additional heat source.
EcoLogic system 2
In EcoLogic system 2, the additional heat is located before the hot water
system, while in EcoLogic system 3 it is located after the hot water system.
Heat pumps A1 and A2 can be connected using diverting valves that direct
the low either to the hot water system or the heating circuit. If more heat
pumps are installed, these should be connected to the heating circuit.
When connecting the buffer tank, the mixing valve (Y4) is used to connect
the tank to the system (not to heating circuit 4).
Solar energy can be connected either to the hot water tank or to the buffer
tank using diverting valves. The solar energy can also be used to recharge
the bedrock/ground.
Cooling can easily be connected to the bedrock/ground source heating
system.
