Johnson Controls TEC
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.Learn More
Ventilation system controller with economizer and CO2-based demand control ventilation capabilities. The device may be configured locally or with wired communication protocols.
- Color touchscreen display.
- BACnet MS/TP supported.
- Good performance under Hub simulated occupancy profiles.
- Also functions as a thermostat.
- Economizer Control Options Single dry bulb change over; Single enthalpy change over; Differential enthalpy change over
|19-30 VAC, 50/60 Hz
|CO2 Sensor Compatibility
|Universal – Works with any CO2 sensor that has the ability to output compatible signal
|Controller CO2 Sensor Input Signal Types
|0-10 VDC, 0-2000 ppm Analog
|Actuator Signal Output Types
|Nominal Power Consumption
|Additional analog inputs include the outdoor air temperature, outdoor air humidity, and supply air temperature.
|Additional binary outputs include first cooling stage command (Y1), second cooling stage command (Y2), first heating stage command (W1), second heating stage command (W2), fan command (G), and heat pump changeover valve command. The thermostat commands may be configured for to control a heat pump with two compressor stages and auxiliary heating.
|Controller Configuration Method
|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. Alerts can be configured if connected to BMS
|Manufacturer Reported Control Algorithm Details
|The TEC3000 features advanced proportional-integral- derivative (PID) control algorithms to maximize control performance while minimizing excessive cycling and wear on the equipment
