CTRL-SP controller for surface mounting (controls up to 10 devices)
-
Installation on a wall surface (not recessed)
- The device draws exhaust air from the room within 70 seconds , , and then, 70 seconds later, fresh air is drawn into the room.
- Warm air from from the , the ceramic heat exchanger, which accumulates heat from the exhaust air. After the unit’s operation , when cold outside air is drawn in, the heat accumulated in the heat exchanger is transferred to the fresh supply air.
- Therefore, utilizes thermal energy that would otherwise be lost.
Every 70 seconds , , the device’s airflow changes 
- The device operates at the that has been selected , activating a two-position switch Ctrl – S
- Speed 1 – ” S1 “
- Speed 2 – ” S2 “
- Speed 3 – ” S1 + S2 “
- The same functionality can be achieved Ctrl – S or two 3-position switches. _
-
S3 switch activates “free cooling” (bypass) mode , which stops the alternating airflow
- This keeps the device in in exhaust mode or air supply mode , it does not reset . Configuration using the JUMPER setting
| Air Exhaust Mode | Air supply mode |

- Automatic ” Boost ” mode is activated by the sensor SEN – HY sensor
Synchronization
- If the equipment are installed in pairs, one unit extracts air from the room while the other supplies it from outside, and vice versa.
