TR42 / Honeywell Wall Module

The TR40 and TR42 series room sensors and displays are designed to work with Trend IQX controllers. All models feature an integrated temperature sensor, and variants are available that also include relative humidity and/or CO2 concentration sensors. The TR42 has a monochrome backlit LCD screen that can be configured to display sensor readings and allows user control of fan speed, occupancy, and temperature setpoint. Up to 7 devices can be connected to the controller via a two-wire Sylk bus that carries both data and power.
