Two Condenser Head Pressure II
Module
For RNE 55 - 105 Ton units, the Two Condenser Head Pressure II Module
( OE370-23-HP2C2) will monitor two head pressure transducers and
control two condenser fans or water valves. A pulse width modulation
(PWM) signal or a 0-10 VDC output signal is used to control these
condenser devices. See Figure 34 below for the wiring diagram.
The Two Condenser Head Pressure II Module connects to the Full Digital
Module, the Water Source Heat Pump Module, or the RNE Controller
with an HSSC cable. This allows setpoints, status values, and alarms to
be communicated between the RNE Controller and the Two Condenser
Head Pressure II Module. This module requires a 24 VAC power con-
nection with an appropriate VA rating.
NOTE: For more information, see the Two Condenser Head
Pressure Module II Technical Guide found on our
website orioncontrols.com.
