RSMZ Input Wiring
The RSMZ monitors and controls one refrigeration circuit of the
HVAC unit. The RSMZ is used on RZ units and on RN-E units
with Danfoss compressors. The module is designed for R410-A
refrigerant.
The RSMZ is connected to the AAON unit controller. Three or
six RSMZ Modules can be connected, depending on the size of
the system. There are two E-BUS Expansion Ports which allow
the use of communicating sensors and E-BUS Modules. There
is a MODBUS terminal block which allows wiring to the Reheat
Expansion Module or VFD Compressor.
The RSMZ must be connected to an 18-30 VAC power source.
When wiring the RSMZ, its relay outputs must be wired as wet
contacts (connected to 24 VAC). See Figure 2, this page for
RSMZ input wiring for modules 1, 2, 4, and 5.
WARNING: Observe Polarity! All boards must be wired
with GND-to-GND and 24 VAC-to-24
VAC. Failure to observe polarity will result
in damage to one or more of the boards.
