Sequence of Operation and Wiring
Occupied Mode
Setpoints revert to those defined by occupied cooling and heating. The occupancy output opens fresh air damper to minimum
position.
Stand-by Mode (only available when PIR motion detector sensor is used)
Setpoints revert to those defined by stand-by cooling and heating.
Unoccupied Mode
Setpoints revert to those defined by unoccupied heating and cooling. The fresh air damper closes.
Occupied Override Mode
System reverts to occupied mode for duration determined by “ToccTime” parameter.
On Call for Cool
If supply water temperature is less than 24°C (75F), cooling valve opens to maintain room temperature, else the valve closes.
On Call for Heat
If supply water temperature is greater than 25°C (77F), heating valve opens to maintain room temperature, else the valve closes.
Supply Air Sensor
Only used for monitoring. Shows automatically if sensor is connected.
