Operation Description Availability On / Off Display Display Fan Speed Control Fan Speed Control Fan Speed Control Bypass Damper Function ModBus Filter Function 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. Free cooling is available, by controlling the indoor and outdoor air conditions. It controls all functions of unit via PC or central control system 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. Optional Optional Optional Boost Function 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 (23V) on PCB board. Safety Fire Alarm Function Wireless Sensors It automatically stops operating in case of interfering to the unit while it is working. It will be active in case of f ire. Upon request, wireless CO2, differential pressure, temperature and humidity sensors are avaliable. Optional Heating Coil Heating coil valves on the devices which include optional heating coil, are controlled by proportional valve motors with PID logic and sensitivity. Optional Frost Control Optional heating coils also include frost thermostat to prevent coil freeze.
