11. ACCESSORIES AND OTHER OPTIONS
The accessories and options usable with URTP devices are as follows:
11.1. CO2 Detector
Constantly checking the system exhaling air, it activates the fresh air damper to the extent that the system allows
(and if the pre-determined temperature settings are in the range) in the point that the air quality gets lower. It
thereby provides more fresh air to the environment.
11.2. Smoke Detector
Constantly checking the system rotational air, it turns off the device and detects a fire alarm to the room control unit
if the amount of CO in the air exceeds the pre-determined amount.
11.3. Filter Dirty Warning
Sending information of the changing filter pressure to the control panel thanks to the different pressure key, it lets
you know that the level of dirt in the filter has increased. The factory pressure setting is 250 Pa. You will receive a
Filter contaminated warning if it exceeds this value.
11.4. Indoor Air Flow Control
The flow can be calculated instantly thanks to the different pressure information readable from the factory-released
measurement nozzles on the plugged fans, constantly checking so that the flow value entered into the system could
remain the same.
11.5. Speed Control of Condenser Fan
With this option offered so that the system will not return an error of low pressure at lower outdoor temperatures,
capacities of condenser fans may be decreased by making its revolutions adjustable. The system can thereby
function properly at lower temperatures.
11.6. Hydrophilic and Epoxy Coating
Depending on the device operation conditions, the interior and exterior heat exchangers of the device may be
applied coating against corrosion and extreme condensation.
11.7. Heat Exchanger Protection Grill
The surface of the device condenser heat exchangers is composed of thin (0.1 mm) aluminum lamellas, it can be
covered with a 4mm painted wire cage for protection of people and animals from these sharp surfaces.
11.8. Gravity Damper
It functions like a non-return valve to prevent unwanted air and particles through the exhaust when the device is not
operating.
11.9. Return Fan
It operates in series with the exhaling air fan and has been designed for the cases where the exhaling air fan cannot
meet the pressure falling on the rotational side. Using the system exhaling fan, it insures that the exhaling fan will
win over the total pressure.
11.10. Power Exhaust Fan
Within the systems operating with a large amount of fresh air, it can be used to export the extra air indoors.
