Mounting and Wiring Considerations
Environmental Requirements
The Two Condenser Head Pressure II Module needs to be installed in
an environment that can maintain a temperature range between -30°F
and 150°F and not exceed 90% RH levels (non-condensing).
Mounting
The Two Condenser Head Pressure II Module is housed in a plastic
enclosure. It is designed to be mounted by using the 3 mounting holes
in the enclosure base. It is important to mount the module in a location
that is free from extreme high or low temperatures, moisture, dust, and
dirt. Be careful not to damage the electronic components when mount-
ing the module.
See Figure 2 for Module dimensions (in inches).

Important Wiring Considerations
Please read carefully and apply the following information when wiring
the Two Condenser Head Pressure II Module:
1. To operate the Two Condenser Head Pressure II Module, you
must connect power to the 24 VAC input terminal block.
2. Each Pressure Transducer must have its own 18-gauge
shielded twisted pair cable. The Drain Wire must be the “Gnd”
signal for the transducer.
3. When the Analog Output is being used to control the
Condenser Fan Speed or Water Valve Percentage, the cable
must be 18-gauge shielded wire, and the Drain Wire must be
the “Gnd” signal.
4. If the Pulse Width Modulation (PWM) Output is being used to
directly control the ECM 142 motor, the wires do not need to
be shielded and can be any 18-gauge wire.
