SCC-300-RTC/SCC-310-RTC Rooftop AC Terminal Unit Controller
A flexible, feature-rich but cost-effective solution for any packaged
rooftop AC unit application. The SCC-300-RTC/SCC-310-RTC maintains a constant
zone temperature by configurable, energy-efficient, sequenced control
of supply fan, heating source, cooling source and optional mixed
air damper and exhaust air damper or fan.
- Configurable resistive inputs for space temperature or supply
air temperature (required) with/without bypass button and any
four of: mixed air temperature, setpoint adjust, fan, filter,
window and occupancy sensors
- Configurable analog input for CO2-based demand control ventilation
or dehumidification control.
- Five digital outputs simplify connecting with standard rooftop
unit five-wire interface
- Side loop provides independent control using spare inputs and
outputs for simple HVAC applications.
- Optimize energy usage with optimum start, demand limiting and
occupied/unoccupied/standby setpoints
- Use spare outputs for secondary heat control
- Built-in alarming, trending and scheduling
- Space Comfort Controller functional profile #8504
- Easy-to-use LNS plug-in software simplifies configuration.
- Optional
DIN rail mounting kit.
Input/Output Summary
