RSMV-HP Wiring
The RSMV-HP monitors and controls one refrigeration circuit of
the HVAC unit. The module is designed for R410-A refrigerant.
The RSMV-HP is connected to the VCC-X / VCCX2 Controller.
Up to 4 RSMV-HP’s can be connected, depending on the size of the
system. There are 2 E-BUS Expansion Ports which allow the use of
communicating sensors and the E-BUS Modules.
The RSMV-HP provides 6 analog inputs, 4 binary inputs, 4 relays,
and 2 analog outputs. See
Figure 2, below for inputs wiring and
Figure 3, page 7 for outputs wiring.

Suction Pressure Sensor Wiring
The OE275-01 Suction Pressure Transducer must be wired as shown
in
Figure 2, below . It is required for all compressorized VCC-X /
VCCX2 applications.
Th e Suction Pressure Sensors are used to measure suction pressure
at the HVAC unit’s DX evaporator coil suction line. Th is suction
line pressure is converted to saturated refrigerant temperature.
Th
e saturated refrigerant temperature is used to properly control
the compressors to maintain a given Suction Coil (Saturated)
Temperature Setpoint. In Cooling and Heat Pump mode, the
VCC-X / VCCX2 resets the Suction Coil (Saturated) Temperature
Setpoint to maintain a given supply air temperature setpoint. In
Dehumidifi cation mode, the Suction Coil (Saturated) Temperature
Setpoint is a user confi gurable setpoint that does not reset.
