Counter Flow Heat Recovery Unit
Operation Description Availability
It automatically stops operating in case of interfering to the unit while it is working.
Upon request, wireless CO2, differential pressure, temperature and humidity sensors are avaliable.
Frost Control Optional heating coils also include frost thermostat to prevent coil freeze.
Heating coil valves on the devices which include optional heating coil, are controlled by proportional
valve motors with PID logic and sensitivity.
Fire Alarm Function
Wireless Sensors
Heating Coil
It will be active in case of f ire.
It is used in order to increase fan speed:Alternative 1: Via boast button on the control panel.
Alternative 2: Via dry contact or light power input (230V) on PCB board.
There are 2 alternatives to control filters:Alternative 1: It records run time of the unit and when
set time expires, control panel gives an alert for filter change.Alternative 2: Filter change time can be controlled with
pressure switch mechanically. By this way, control panel gives an alert when f ilter needs to be changed.
Control panel or external start stop function is available.
Digital control panel is available.
Wireless controller is avaliable as option.
3 steps fan speed control of supply and exhaust fan is available.
Constant air flow is available with pressure sensors.
Airflow control based on the air quality sensor is available.
