FANS

The fans are powered by energy-efficient EC motors. 

HEATER 

A heater (electric or water coil) is supplied as standard. 

TEMPERATURE CONTROL

In cold weather the bypass damper closes and outdoor air is routed 

through the heat exchanger in order to recover the heat from the ex-

tract air (winter mode). The heat that the counterflow heat exchanger 

recovers is generally sufficient. 
When outdoor temperatures are low and the desired supply air tem-
perature cannot be achieved using recovered heat alone, the heater 
assists.
In warm weather the bypass damper opens and the outdoor air is  
routed past the heat exchanger (summer mode).

CONTROL EQUIPMENT

The unit is equipped with an electronic Curo control unit The control 

unit is integrated into the unit and controls the 

 

operation of the fans, the bypass damper and the heater. 

FAN CONTROL

Three operating modes can be selected via the Curo Touch control 

panel: 

•  “AWAY” (low speed) is only used when the premises are left empty 

for an extended period (during a holiday for example) 

•  “HOME” (normal speed) is used for normal ventilation flow 

•  “FORCED” (high speed) is used when there is a greater need for ven-

tilation (reverts to normal automatically after 120 minutes) 

The speed of the fans can be adjusted independently of each other. 

COOLING RECOVERY

In the summer, if the extract air is colder than the outdoor air, the by-

pass damper closes to recover cooling from the colder extract air. This 

applies particularly if there is some form of cooling unit in the facility/

house.

DEFROSTING, TERMO ICE

During cold periods when frost forms in the heat exchanger, the Termo 

Ice function defrosts the unit and the supply air fan is stopped. Defros-

ting does not start until it is really needed. In other words when much 

of the heat exchanger has been covered in frost. This is to allow the 

highest degree of heat recovery possible. The Termo Ice system can 

detect the difference between frost and condensate.

ETHERNET CONNECTION (ACCESSORY)

This function can be used to connect the unit to an existing network. 

The unit has an integrated web server, which makes it possible to read 

and change certain parameters via a web browser.
The connection can also be used for connection to a superior system 

via Modbus TCP/IP.

ENERGY CLASS

Compliant with energy class A+ in cold climate conditions (Scandinavia).
