Product Description1

This document describes the hardware installation procedures for the SAUTER EY-modulo4 room
operation units with display for Variable Air Volume applications (VAV) and Balancing Tool and for
Fan Coil applications (FC).

The SAUTER EY-RU483F001 communicating sensor and balancing tool for VAV is specifi cally
designed to work with the EY-RC415 and EY-RC416 controller product lines. This device provides
precision local temperature sensing and it allows occupants to adjust the local setpoint and view
the occupancy status, local space temperature, outside air temperature and operation mode.

Maintenance personnel have access to a password-protected advanced mode that allows them
to perform air balancing on a connected EY-RC415 or EY-RC416, send service pin messages for
commissioning and toggle temperature units between °C and °F.

The SAUTER EY-RU483F001 can be permanently installed on a wall or used as a hand-held air
balancing tool that can be connected through a standard wall-mounted room sensor. Using the
SAUTER EY-RU483F001 as a hand-held unit, technicians can directly perform VAV balancing right
near the point of control.

The SAUTER EY-RU482F001 communicating sensor is specifi cally designed to work with the
EY-RC402 and EY-RC403 controller product line. This device provides precision local temperature
sensing and it allows occupants to adjust the local setpoint and fan speed and view the local
space temperature.
