Outdoor Temperature Sensor for Venstar Thermostats
The ACC0400 accessory transmits outdoor air temperature to compatible Venstar thermostats including the T1100FS, T1700, T1800, T1900, T2700, T2800 and T2900 models. It also functions as a remote room sensor for the T1800, T1900, T2700 and T2900 units. The thermostat displays a blinking degree icon when controlling to the remote sensor reading. High and low daily outdoor readouts appear on the T1800, T1900, T2800 and T2900 thermostats.
Requires 3-Conductor Thermostat Wire
Installation demands a three-conductor thermostat wire run between the sensor location and the thermostat. Without this specific wiring the accessory cannot communicate temperature data to the controller. The sensor measures temperatures from 0 to 160 F whether mounted indoors or outdoors. Buyers without existing three-conductor cable or the ability to pull new wire cannot use this sensor.
Enables Outdoor Readouts and Remote Control
When configured as an outdoor sensor the accessory adds high and low temperature history to supported thermostat displays without affecting heating or cooling decisions. When configured as a remote room sensor it shifts the control point to the sensor location so the thermostat maintains the temperature where the sensor sits rather than at the thermostat itself. The sensor does not add wireless connectivity, smart-home integration or additional relay outputs.

Questions about this item
How does the 0 to 160 F range work when the sensor is installed outdoors?
The sensor measures outdoor air temperature across the full 0 to 160 F range and transmits the reading to compatible thermostats for display of daily high and low values.
What wiring standard does the ACC0400 require and what does it limit?
It requires a 3-conductor thermostat wire, which carries power and signal between the sensor and the thermostat.
Which Venstar thermostat models can this sensor mount to and function with?
Compatible models include T1100FS, T1700, T1800, T1900, T2700, T2800, and T2900 for outdoor sensing, with T1800, T1900, T2700, and T2900 also supporting remote room sensing.
