Johnson Controls Peak
Demand Control Ventilation (DCV) controllers integrate with the building ventilation system to modulate the amount of outdoor air based on input from a CO2 sensor. They can be used to save energy during low occupancy and improve indoor air quality during high occupancy.

Model Number | PK-ECO1001-0 |
Power Supply | 20-30 VAC, 50/60 Hz |
Controller CO2 Sensor Input Signal Types | 0 to 10 VDC, 0-2000 ppm Analog |
Actuator Signal Output Types | 0-10 VDC or 2-10 VDC |
Nominal Power Consumption | 15 VA. Does not include any sensors or actuators |
Economizer Control Options | Single dry bulb change over; Single enthalpy change over; Differential enthalpy change over |
Other Inputs | Additional analog inputs include the supply air temperature, outdoor air temperature, outdoor air humidity, return air temperature, return air humidity, building pressure input, outdoor air flow, and damper feedback position. Additional binary inputs include first cooling stage status (Y1), second cooling stage status (Y2), heating stage status (W1), shutdown status, purge status, and occupancy status. |
Other Outputs | Additional binary outputs include alarm output, first cooling stage command (Y1), second cooling stage command (Y2), and exhaust fan output |
Controller Configuration Method | Local (display) |
Controller Response to CO2 Sensor Failure/Power Loss | The controller logic is reconfigured to ignore DCV settings. DCV settings are maintained in memory and restored when power is restored. Controller defaults to economizer mode. |
Manufacturer Reported Control Algorithm Details | A Pattern Recognition Adaptive Control (PRAC) algorithm tunes Proportional-Integral (PI) feedback loops |
Supported Communication Protocols | BACnet MS/TP communication |
