8.8.4 Define cooling (accessory)
(Only applies to EcoPart.)
Cooling is adjusted using primary flow sensor 2 (B2), 
which means that radiator system 2 and cooling cannot 
be used simultaneously.
Common heating/cooling  No
Cooling  No (No/Yes)
This is for selecting whether cooling is installed.
Condense pipe secured  No (No/Yes)
If a condense pipe for the system has been secured, 
significantly lower temperatures are permitted at 
various points in the system. WARNING Build-up of 
condensation in the house structure can lead to damp 
and damage from mildew.
(No) means a setting range for room temperature of 
18–30ºC and (Yes) means a setting range of 10–30ºC
In the event of doubt, contact an expert surveyor for an 
assessment.
Room temperature cooling  25 (10 or 18...30)
This is used to set the desired room temperature for 
cooling. 
See the CTC EcoComfort manual for more 
information.
