Power Requirements
Cresnet®: 24 Volts DC
HVAC Unit: 24 Volts AC
Power Consumption: Approximately 1.5 Watts

Communications[1]
Cresnet

Fan Coil Unit Control
Fan Control: Variable speed control via 0-10 Volt signal;
20 mA max sink or source
Cooling: Variable valve control via 0-10 Volt signal;
20 mA max sink or source
Heating (Modulating Valve): Variable valve control via 0-10 Volt signal;
20 mA max sink or source
Heating (Relay): Contact closure to HVAC

Buttons
HOT/COLD: Toggles between Heat and Cool modes
FAN: Controls fan speed;
Cycles through Auto, High, Medium, Low, and Off settings
UP: Raises the room’s setpoint by 1° F or 0.5° C, depending on the active temperature scale
DOWN: Lowers the room’s setpoint by 1° F or 0.5° C, depending on the active temperature scale
°F/°C: Toggles between Fahrenheit and Celsius temperature scales

Motion Sensor
On-board passive infrared sensor;
Enables thermostat to toggle between two previously defined setpoints;
When motion is detected, the Occupied setpoint is used;
When the room is vacant, the Unoccupied setpoint is used

Display
