2.1 Alt. 1. Connection to the CTC controlling
product, common underfl oor heating/cooling
The diagram shows schematically how CTC EcoComfort is connected to the systems; additional
equipment, such as expansion vessels, shut-off valves, safety valves, buffer tank etc., is not shown
here. The controlling product in this example is the ground source heat pump CTC GSi. In this
example (Alt.1), the diverting valve Y60 is connected to the combined heating/cooling circuit as well
as to the controlling product and CTC EcoComfort. The diverting valve is controlled by the controlling
product.
