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:
•
•
•
•
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:
•
•
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:
•
•
•
•
•
•
•
•
COMM3/4 Communication Interface
Allows ICS communication between a ReliaTel unit and Trane ICS systems as follows:
•
•
•
•
•
•
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).
