RT-SVX34C-EN 43
Installation Electrical
Variable Air Volume Control Options
The RTRM must have a mode input in order to operate the rooftop unit. The normal mode selection
used with a remote panel with or without night setback, or ICS is AUTO and OFF. Table 9 lists the
operating sequence should a CV zone sensor be applied to a VAV system having selectable modes;
i.e. Fan selection ON or AUTO. System selection HEAT, COOL, AUTO, and OFF.
Default Mode Input for Discharge Air Control
For unit stand-alone operation without a remote panel or an ICS connected, jumper between
terminals J6-2 and J6-4 on RTRM.
VHR Relay Output
For stand alone VAV unit operation, the VHR output should be wired to drive VAV boxes to
maximum position during all heating modes and unoccupied periods. The VHR contacts are shown
in the de-energized position and will switch (energize) during the above mentioned operating
modes.
