Page 18: Placement Of The Heat Pump
• CTC EcoAir 400 is normally placed on an outside wall. • There should be a space of at least 250 mm (EcoAir 406-410) or 400 mm (EcoAir 415-420) between the product and the wall so that outdoor air can pass freely in through the evaporator. -
Page 19: Preparation And Drainage
General Information 7. Preparation and drainage The heat pump should be positioned so that the house cannot be damaged and the condensation water can easily drain into the ground. The foundation should be of concrete blocks or similar, resting on crushed stones or gravel. •... -
Page 20: Condensation Water
General Information Condensation water • The condensation tray is built into the heat pump and is used to divert most of the condensation water. The tray can be connected to a suitable drain. Connection diameter: 42mm. • A heating cable (available as an accessory) should be placed in the pipe to prevent refreezing. -
Page 21: Pipe Installation
General Information 8. Pipe installation The installation must be carried out in accordance with current MCS standards. Refer to MIS 3005 and associated building regs Part L,F & G. The boiler must be connected to an expansion vessel in an open or closed system. -
Page 22: Example Pipe Connection
General Information Example pipe connection EcoAir/EcoZenith i250 L The CTC EcoZenith i250 L has pipes at the rear right edge for connection of the heat pump. The heat pump’s lower connection is connected to the right connection when viewed from the front, so that water is pumped out to the heat pump. -

Page 25: General Function Description
General Information 10. General function description 10.1 Defrosting The CTC EcoAir 400 is fitted with hot gas defrosting. The heat pump checks constantly whether defrosting is needed and, if so, defrosting starts, the fan stops, the four-way valve changes direction and the hot gas goes to the evaporator instead. -
Page 26: Electrical Installation
General Information 11. Electrical installation The installation and heat pump connection must be done by an authorised electrician. All wiring must be installed according to valid requirements. The communication cable used is an LiYCY (TP) which is 4-conductor shielded cable, where the communication-bearing conductors are of twisted pair type. -
Page 27: Shielded Communication (Grey Connector)
General Information 11.2.1 Shielded communication (grey connector) The loop (5), which connects position 4 of the control terminal block and PE on the mains terminal block, must be removed on all heat pumps in the connection chain except the last and replaced (at position 4 on the control terminal block) by the shielding, which is then connected up to the next heat pump. -
Page 28: Ctc Basic Display (Accessory)
General Information 11.3 CTC Basic Display (accessory) The heat pump can be run without a controlling system (standalone), but it must be supplemented with the CTC Basic Display accessory. The CTC EcoAir 400 can then be controlled with a fixed return temperature or with CTC Basic Display (accessory) thermostatic control. -
