atmospheric pressure. The Space Pressure Setpoint and Space Pressure Deadband are set by
adjusting potentiometers located on the RTVM.
The RTDM (Dehumidification Module) provides a pulsed signal output to control the Cooling and
Reheat Modulating Valves. The RTDM will also monitor the Entering Evaporator Temperature as
well as protect against a low refrigerant pressure in the reheat circuit.
DIP Switches:
Switch 1 is "OFF" for IGV's and "ON" for VFD's.
Switch 2 is "OFF" for VAV, "ON" for VAV without IGV.
Switch 3 and 4 operation are explained under "supply air temperature reset".
Switch 5 is "OFF" for DWU Disabled and "ON" for DWU Enabled.
Conventional Thermostat Connections (Standard with CV)
This feature allows conventional thermostats to be used in conjunction with the RTRM on Constant
Volume Applications only. It utilizes the conventional wiring scheme of R, Y1, Y2, W1, W2/X, and
G. Refer to Figure 21, p. 41 for conventional thermostat connections. Applicable thermostats to be
used with the conventional thermostat inputs are:
TCI - Trane Communication Interface (Optional)
This module is used when the application calls for an ICS building management type control
system. It allows the control and monitoring of the system through a Trane Tracer™ panel. The
module can be ordered from the factory or ordered as a kit to be field installed. Follow the
installation instructions that ship with each kit when field installation is necessary.
LCI - LonTalk® Communication Interface (Optional)
This module is used when the application calls for a LonTalk building management type control
system. It allows the control and monitoring of the system through a Trane Tracer Summitt panel
or 3rd party LonTalk system. The module can be ordered from the factory or ordered as a kit to be
field installed. Follow the installation instructions that ship with each kit when field installation is
necessary.
BCI - BACnet® Communication Interface (Optional)
This module is used when the application calls for a BACnet building management type control
system. It allows the control and monitoring of the system through a Trane Tracer SC panel or 3rd
party BACnet system. The module can be ordered from the factory or ordered as a kit to be field
installed. Follow the installations instructions that ship with each kit when field installation is
necessary.
Manual Motor Protectors (380V through 575V Only):
Manual motor protectors will be used as branch circuit protection for compressors and supply fan
motors. These devices are capable of providing both overload and short-circuit protection.
Before operating, the manual motor protector must be switched with the rotary on/off switch to the
“ON” position and the overload setpoint dial must be set to the appropriate rating of the motor.
