General Information
The Complete System
CTC EcoAir 510M
CTC EcoAir 510M is a modulating air source heat pump
that takes heat from the outside air and supplies it to the
existing heating system in the house. The heat pump
works with outdoor temperatures down to -22°C.
The CTC EcoAir 510M has been designed to operate
with high efficiency and low noise levels. The heat pump
has integrated hot gas defrosting which keeps the
evaporator coil free from ice to maintain high efficiency.
Control
CTCEcoAir520M is controlled by these products.
• CTCEcoZenithi250
• CTCEcoZenithi350
• CTC EcoVent i 350 F
Ecodesign information relating to the current
combination (current package) can be downloaded from
www.ctc.se/ecodesign. Energy labelling stickers can
also be printed from here.

!Note: In case of deviations, the product's data plate
applies. When servicing always check the product's
data plate for correct refrigerant quantity.
* The sound specified should be regarded as an indication since the level
is affected by the compressor’s and the fan’s speed, as well as the
surroundings. The upper value corresponds to 100% reflecting ground and
walls (smooth concrete).
