RT-SVD03G-EN 41
ReliaTel Ventilation Module (RTVM)
RTVM Layout
27.5 to 50 Ton
The RTVM is installed in the economizer section for V3 units with Statitrac.
RTVM Inputs
J1, J2 Inputs:
J1 provides 24VAC power in to the board and MODBUS communication to and from the RTRM. J2
provides 24VAC power and MODBUS communication downstream to the ECA.
J3 Inputs:
J3 - 1, 2 inputs allow configuration for Statitrac Control. If closed, the unit is configured for Statitrac
control.
J4 Inputs:
J4 - 3, 4, 5 provide 5Vdc to the Space Pressure Transducer, an input for the space pressure signal
to the control board, and a common for the transducer.
J5 Output
J5 - 1, 2 provides a 2-10Vdc output signal and common to the exhaust damper actuator.
