Distech Controls ECLYPSE ECY-303 - Multi State Input Variables

32 ECY-303 Preloaded Applications
ID Units Valid Range Default Value
Binary Value 25 Yes/No Yes to No Yes
Multi State Values
OccupancyCmd (MSV1)
This variable is used to receive the occupancy information from the BMS system.
This input is used in conjunction with the motion detection (MSV6) to determine the effective occu-
pancy mode. Refer to the OccupancyStatus (MSV15) for more information.
ID Enumeration Default Value
Multi State Value 1
1 = Occupied: The HVAC controller should operate in the occupied
mode
2 = Unoccupied: The HVAC controller should operate in the unoccupied
mode
3 = Bypass: The HVAC controller should operate in the occupied mode
4 = Standby: The HVAC Controller should operate in the standby mode
Occupied
HvacModeCmd (MSV2)
This variable is used to coordinate the hvac controller with the BMS system. If the system is in another
mode than Auto, the hvac control loop will be forced into this mode.
ID Enumeration Default Value
Multi State Value 2
1 = Auto (Mode determined by unit)
2 = Heat (Use heat setpoints)
3 = MrngWrmUp (Use heat setpoints)
4 = Cool (Use cool setpoints)
5 = NightPurge (Use cool setpoints)
6 = PreCool (Use cool setpoints)
7 = Off (No unit operation allowed)
Auto
FanModeCmd (MSV3)
This variable is used to configure the fan control mode based on the OccupancyStatus.
ID Enumeration Default Value
Multi State Value 3
1 = On: When OccupancyStatus(MSV15) is occupied, the fan is set to
On. When in Unoccupied, Bypass or Standby mode the fan is controlled
based on the terminal load like in Auto mode.
2 = Auto: The fan start is controlled based on the terminal load. When
the terminal load is at 0%, the fan is off.
3 = Off: The fan is always set to Off.
On
AuxContact (MSV4)
This variable is used to display the actual status of an auxiliary contact configured on inputs between
UI1 to UI5.
ID Enumeration Default Value
Multi State Value 4
1 = Active: Auxiliary Contact is activated.
2= Inactive: Auxiliary Contact is Inactive.
3= Unconfig: Auxiliary Contact is not used.
