1.1 Features and Benefits
• Stand-alone thermostat algorithm or fully BACnet network-controllable
•
BTL listed with B-ASC device profile for seamless integration into BACnet networks
• 24VAC (+/-10%) power input
•
Manual-changeover or Auto-changeover control types
• BACnet/IP over Wi-Fi can be integrated into any 802.11 b/g/n Wi-Fi network
•
Suitable for single to multi-stage heat/cool control applications with manual or
automatic changeover between heating and cooling modes
•
Adjustable algorithm applied to multi-stage step control
• Adjustable minimum on/off time staging for optimizing runtime
•
Effective run time accumulation for system runtime for energy consumption metering
• Full configurable control parameters such as deadband, proportional gain, integral
rate, stage trip points, and cycle time
•
Adjustable minimum/maximum set point ranges
•
Three options for temperature reading:
o
Built-in temperature sensor, or
o Remote sensor (RS) input for wiring in a remote temperature sensor (NTC
3kΩ), or
o
BACnet network temperature override
• Occupancy status can be switched from thermostat buttons by occupants or using
BACnet network command.
•
Separate adjustable occupied set points for heating and cooling mode
•
Separate adjustable unoccupied set points for heating and cooling mode
• Fan can be set to run continuously or automatically depending upon fan mode
•
Non-volatile memory (EEPROM) retains user settings during power outage
• Thermostat buttons are selectively lockable to prevent unauthorized control
•
°C or °F display
•
Control outputs disabled during “OFF” state for safety
