Overview

The TR75 Zio Plus sensors are 2-wire, non-polarity sensitive, Sylk bus communicating wall modules for use with Spyder® and ComfortPoint™ programmable controllers. All models have a space-temperature sensor, network bus jack, and an LCD panel with three softkeys and two Up/Down adjustment keys. The Zio Plus also includes access to controller schedule and has more memory for additional parameters than the Zio sensors. The TR75-H models include an onboard humidity sensor.

Features

  • Ability to control user access to controller parameters.
  • Parameter access can be customized by using the Tridium Niagara Workbench tool.
  • Programmable for: Home screen options, tenant access, contractor access, access to controller parameters, setpoint, override, fan, and other parameters.
  • Supplied with eight pre-programmed configurations (e.g. VAV with balancing) in the wall module configuration tool.
  • Ability to access and adjust most parameters in the programmable controller (including Scheduling).
  • Ability to balance the VAV system from the wall module.
  • Home screen can display one to three of any of the following parameters: Temperature Setpoint, Room Temperature, Room Humidity, Outdoor Humidity, Outdoor Temperature, and Time, or one of virtually any parameter in the controller.
  • Network bus jack.
  • Simple 2-wire terminal connection to the programmable controller and an optional 2-wire terminal connection for the network. All connections are polarity insensitive.
  • Retention of user configuration, including setpoints after a power outage.
