Room Sensors and Displays Honeywell
The TR40 and TR42 series of room sensors and displays are designed to operate with Trend IQX controllers.
All models have an integral temperature sensor and variants are available that also include sensors for relative humidity and/or CO2 concentration. The TR42 features a monochrome backlit LCD display which can be configured to show sensor readings and allow user control of fan speed, occupancy and temperature setpoint.Up to 7 devices can be connected to the controller by a two wire Sylk™ bus which carries both data and power.
Features
▪ Single power/data connection to controller reduces wiring.
▪ Temperature sensing plus versions with humidity and/or CO2
▪ Operates in either °C or °F.
▪ Common backplate and connections allows easy upgrade from TR40 to TR42.
Display Value: Shows the current value for any of the following:
▪ temperature in either °C or °F (up to 1 decimal place)
▪ humidity in %
▪ CO2 concentration in ppm (parts per million)
▪ temperature setpoint in either °C or °F
▪ device name
It can also be configured to scroll through any settings that are visible in the MORE menu, or to display nothing.
Function Buttons
The TR42 has two function buttons which invoke the function indicated by the label (or icon) displayed above them.
Depending on the device configuration, the buttons can have the following primary functions on the home screen:
Main Display
The display is used present a range of different information and, where required, provide the user with selectable options to change certain settings.
In normal operation (i.e. no buttons being pressed), the display's 'home' screen can be configured to display:
▪ a value (e.g. temperature, humidity and CO2 values),
▪ the current fan state, and
▪ the current occupation state.
