- Page 23 Filling and venting Mix water and antifreeze solution in an open vessel. Connect hoses to the shut-off valves (98a and 98b) as shown in the figure. Connect a powerful external pump (101) for refilling and bleeding. Then reset the three-way valve (100) and open the valves (98a and 98b) so that the brine passes through the mixing container (102).
- Page 24 Air pockets To avoid air pockets, make sure that the collector hoses constantly rise towards the heat pump. If this is not possible, it must be possible to bleed the system at the high points. The filling pump usually manages smaller local height discrepancies.

Page 28: Ctc Ecopart 425-435
CTC EcoPart 425-435 The CTC EcoPart 425-435 has two CTC Basic Display units mounted behind the front panel. The displays are used to address the cooling modules when connecting more than 1 product (2 cooling modules) in series, for example A2 to A4 and A1 to A3, etc. -
Page 29: Series Connection Of Heat Pumps
Series connection of heat pumps When more than one product (two cooling modules) is connected, the subsequent cooling modules must be addressed correctly. The CTC Basic Display on these products can be used to name these products as shown below, see the manual for the CTC Basic Display. The last heat pump (the cooling module) connected in series must be partly terminated and the shielding in the communication cable must be connected to earth, see below. -
Page 30: Shielded Communication
5.3.2 Shielded communication When there is a series connection, the loop which connects position Sc of the control terminal block and PE on the mains terminal block must also be removed and replaced by the shielding, which is then connected up to the next heat pump (control terminal block position Sc). -

Page 32: Connecting The Control System
Connecting the control system 5.4.1 Defi ne number of heat pumps Define the heat pumps in the controlling product’s display under: "Advanced/Define system/Heat pump". Set the heat pumps contained in the system to position "On". Example of a system with 3 heat pumps. 5.4.2 Numbering CTC EcoPart as VP2 Applies to control launched in October 2020 with three connectors on the back of the display. - Page 33 5. The heat pump is now numbered (VP2). When you press OK, (VP1 and VP3)* disappears and the row "Current address/New Address" will go dark. *In this example, we have assumed that the heat pump is called VP1, which is the factory default. If the heat pump has already been renumbered, then select this number instead.
-
Page 34: Worth Knowing When Addressing
When all heat pumps are numbered and energised, they should be displayed when you press the heat pump symbol in the menu “Operation data”. If any heat pump does not appear in the menu (communication with the heat pump fails) It may be because it has not been numbered as described above. -
Page 35: Numbering Ctc Ecopart As A2
5.4.4 Numbering CTC EcoPart as A2 Applies to older controls with 2 connectors on the back of the display. 1 RJ-45 and 1 RJ-12 for the CTC EcoZenith i550 Pro and CTC EcoLogic Pro/Family. RJ-12 RJ-45 1. System disconnected from power. 2. - Page 36 6. The heat pump is now numbered (A2). 7. To number the other heat pumps: Energise the control and the next heat pump to be numbered, which will be numbered pump 3 (A3). 8. Wait approx 2 minutes until the heat pump is visible in Operation the operational information.
- Page 37 11. Redo the procedure according to the number of heat pumps to be numbered. When all heat pumps are numbered and energised, they should be displayed when you press the heat pump symbol in the menu “Operation data”. If any heat pump does not appear in the menu (communication with the heat pump fails) It may be because it has not been numbered as described above.
