The complete heat pump for bedrock, ground or lake heat sources The CTC EcoPart 400 is a heat pump that takes heat from bedrock, ground or lake heat sources and supplies it to the existing heating system in the house.
• Any work done on the product’s electric or cooling system should be done by a competent engineer. • This product is intended exclusively for indoor installation. Failure to follow the instructions in this Manual may void the Warranty. CTC EcoPart 400...
IR 12 CTC 400 Alternative B The CTC EcoPart 400 can be operated with an existing boiler via the CTC Basic Display accessory. This can be done with a fi xed temperature or based on thermostatic control. Given that the standard version of the CTC EcoPart 400 does not have its own controller, the CTC Basic Display accessory is required.

IR 12 CTC 400 CTC EcoLogic Pro CTC Basic Display CTC EcoPart 400 The CVTC Basic Display is needed only when more heat pumps are to be connected in series, namely for proper addressing the individual heat pumps: A2, A3 etc.
General information 7.2 Wiring alternative 2 The CTC EcoPart 400 can be operated with an existing boiler via the CTC Basic Display accessory. This can be done with a fi xed temperature or based on external thermostatic control. Given that the standard version of the CTC EcoPart 400 does not have its own controller, the CTC Basic Display accessory is required.
