SCC Controller

The following functions can be selected via the SCC:
- Set temperature^* (for ventilation in steps)
- Set negative pressure (for flap control)
- Air humidity (for cooling control)
- Minimum ventilation level
- Band width
- Heating / Cooling difference
- Minimum alarm level
- Maximum alarm level

The SCC is a ventilation regulator that controls the ventilation by means of stepcontrol (max. 6 steps). For the minimum ventilation level the first step can be switched cyclical. It is possible to keep the negative pressure at a constant level by controlling the air-inlet with an exra negative pressure sensor. The heating and cooling are switched on/off by means of a relay.
When using an extra air humidity sensor, the cooling can be switched off when the air humidity rises too high.

The setting of the functions is very simple. Pressing the corresponding symbol on the front of the device to enter a setting or regulation. The selected button will light up as an indication that the selected setting or regulation has been activated. Use the two arrow buttons to increase or decrease the relevant value.
