14.3.9 EcoZenith – CTC EcoComfort (Cooling)
CTC EcoComfort is an accessory which utilises the cool temperatures of
the borehole to create a cool indoor climate in summer. By connecting
EcoComfort to the separate fan convectors, its water is cooled using the
bedrock’s cooler collector water. The heat in the house is supplied to the
borehole in the bedrock.
CTC EcoComfort comes supplied pre-connected from the factory and is
easy to connect to the system.
The cooling function is controlled entirely from your EcoZenith where you
can also perform your own settings as to when and how you want cooling to
take place.
See also “Cooling” Menu in the “Detail menu description” chapter (“Installer/
Define system/Passive Cooling”).
This type of cooling function is energy efficient, as only circulation pumps
circulate the cool water. The capacity is however slightly lower compared to
what is known as active cooling where the compressor, which requires more
energy, is operated to generate cooling.
The system can be connected to separate fan convectors.
If separate fan convectors are connected, provided the system is insulated
against condensation and there is a condensate collector in the fan
convectors, much lower temperatures may be permitted.
See CTC EcoComfort manual for more information.
