Features and Benefits

1.1
• Stand-alone thermostat algorithm or fully BACnet network-controllable
• BTL listed with B-ASC device profile for integration into BACnet networks
• 24VAC (+/-10%) power input
• BACnet MS/TP with baud rate selections up to 76.8kbps
• Suitable for 4-pipe modulating heat/cool control applications with manual or automatic
changeover NOTE: 2-pipe heat/cool applications and floating-type valve actuators are
not supported by this device
• Adjustable algorithm applied to modulating valve control
• Effective run time accumulation for energy consumption metering
• Full configurable control parameters such as deadband, proportional gain, integral rate
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 (1) locally by the user, (2) by using a separate
occupancy sensor, or (3) by using BACnet network command.
• Separate adjustable occupied and unoccupied set points for heating and cooling mode
• Fan can be set to run continuously or automatically
• Non-volatile memory retains user settings during power outage
• Thermostat buttons are lockable to prevent tampering
• °C or °F display
• Energy Savings Input (ESI) for local occupancy control
• Control outputs disabled during "OFF" state for safety
