The CF benefits ensuring the lowest possible energy
consumption, quiet operation and an exceptional performance
range covering small apartments to large houses.
• Quiet operation • Integrated digital controller • Light-weight for easy installation • Plug and play controls • BMS connectivity (Building Management System) • LS inputs/ (Light Switch) • Volt-free inputs • Self diagnosis for simplified fault finding • Adjustable delay on/delay off timer • 0 to 10V propotional inputs
General The efficient counterflow heat exchanger ensure a temperature efficiancy up to 92% (according to EN 308). Automatic summer bypass (BP) will provide the house with cool outdoor air during summer. Individually speed adjustment on supply and extract fan. Possibilty to demand control ventilation by humidity, CO² etc. The fully automatic capability of the CF range means that adequate ventilation is always achieved. The CF:s BMS capability is also ideal for commercial applications where landlords or property managers want to monitor and optimise building performance and maintenance. The CF BMS can provide status information and it's self diagnostics can report if any fault is found.
Frost protection The CF has a automatic frost protection of the heat exchanger. If the frost protection will be activated the unit will start to decrease the speed of supply fan. This will be done in several steps. To prevent that the automatic frost protection will start, an additional pre-heater can be installed on outdoor ducting. The pre-heater has it's own temperature and flow control and will run separatly. For the CF250V there is a pre-heater of 1,2 kW and for the CF400V 2,0 kW. These pre-heaters can ensure a safe operation of the unit down to a outdoor temperature of -20 °C.
Quick Change filter As many systems are placed within cupboards the unique filter design folds as you remove it to ensure easy access in restricted spaces.
Integral Humidity sensor The integral humidity sensor increases speed in proportion to relative humidity levels, saving energy and reducing noise. The sensor also reacts to small but rapid increases in humidity, even if the normal trigger threshold is not reached. This unique feature ensures adequate ventilation, even for the smallest wet-room. Night time relative humidity setback feature suppresses nuisance tripping as humidity gradually increases with falling temperature.
