10 RT-SVD03G-EN
General Information
Reliatel Ventilation Module (RTVM)
The RTVM is a module required for units configured with Space Pressure Control with Statitrac. The
module controls the Exhaust Damper Position 0-10Vdc output as well as the Space Pressure Sensor
calibration routine. The module accepts the following inputs:
• Statitrac Configuration.
• Space Pressure Input.
• Space Pressure Setpoint.
• Space Pressure Setpoint Deadband.
Reliatel Dehumidification Module (RTDM)
The RTDM is a module required for units configured with Modulating Dehumidification. The
module controls Modulating Cooling and Reheat valves as well as the Reheat Circuit Pumpout
Solenoid. The module accepts the following inputs:
• Reheat Circuit Entering Evaporator Temperature.
• Reheat Circuit Low Pressure Cutout Input.
Economizer Actuator w/ Module (ECA or RTEM)
The economizer can be used with or without the Options module. The actuator has a detachable
communicating module, which can be replaced separately. The outdoor air sensor, connected to
the RTRM, provides outdoor temperature information for the changeover decision.
The ECA accepts the following inputs:
• Mixed Air Sensor (MAS).
• Return Air Sensor (RAS) for comparative enthalpy or ICS input data.
• Outdoor Humidity Sensor (OHS) for reference or comparative enthalpy.
• Return Air Humidity Sensor (RHS) for comparative enthalpy.
•CO
2
Sensor 0-10VDC input.
• Remote Minimum Potentiometer (RMP).
• Active/Passive DCV Configuration Input (RTEM only).
• The Power Exhaust relay is connected to the ECA module as well.
COMM3/4 Communication Interface
Allows ICS communication between a ReliaTel unit and Trane ICS systems as follows:
• Tracer™ 100 series
• Tracer™ Summit
•Tracker™
•ComforTrac™
• VariTrac™ 1 (Comfort Manager)
• VariTrac™ 2 (Central Control Panel)
LonTalk® Communication Interface
Allows Building Management System (BMS) communication to a ReliaTel unit. There are 2 LCI
versions, one for SCC control (constant volume units) and one for DAC control (VAV units).
