AUTOMATION AND CONTROL SYSTEM |
VUT EH CONTROL AND PROTECTION FUNCTIONS |
-
The unit incorporates an integrated automation and control system with a multi-functional control panel with LCD display.
-
The standard delivery set includes 10 m connection cable for connection to the remote control panel.
-
The unit has the freezing protection function to prevent the heat exchanger freezing by means of actuating the bypass damper and controlling water heater.
-
As the temperature sensor warns of the freezing danger, the bypass air damper is opened and the intake air is directed through the air duct beside the heat exchanger.
-
As the heat exchanger is warmed the supply air temperature rises up to the set level while passing through the heater.
-
Meanwhile the warm extract air warms up the heat exchanger.
-
After the freezing danger is no longer imminent, the bypass damper shuts the bypass duct and the unit reverts to the standard operation mode.
|
- Control from the control panel: switching on/off, speed selection, timer, faults;
- Maintaining the set room temperature by the sensor on the control panel – smooth heating capacity control;
- Three-speed fan speed control (low-medium-high);
- Unit operation according to daily and week schedule (timer adjustable from the control panel);
- Safe start-up/shutdown of the fans;
- Electric heater overheating protection by the temperature sensor installed in the supply air duct and by two overheating thermostats, one thermostat activated at 60 °C with automatic reset and another thermostat activated at 90 °C with manual reset. Blowing of the heating elements for heat removing at the end of the heating cycle;
- Filter clogging control by filter time.

MOUNTING |
OPTIONS |
- The unit is designed for indoor mounting. While mounting the unit provide the correct condensate collection and drainage.
- Access for the unit servicing and filter cleaning is from the side panels on the left from supply air side.
|
- For attenuation of sound generated by the fans it is recommended to install the duct silencer (refer SR) from inside before the unit.
- For vibration absorbing it is recommended to install the flexible antivibration connectors (refer VVG) on both sides of the unit.
