Installation & Wiring
Power Supply
The Two Condenser Head Pressure Module requires a 24 VAC power
connection with an appropriate VA rating.
If you will be connecting the Two Condenser Head Pressure Module to
any of the VCM-X series controllers, one of the most important checks
to make before powering up the system for the fi rst time is to make sure
that the controller is confi gured properly for your application. Refer to
the VCM-X Controller Technical Guide or VCM-X Modular E-BUS
Controller Technical Guide for more information.
WARNING: Observe polarity! All boards must be wired
GND-to-GND and 24 VAC-to-VAC. Failure to
observe polarity could result in damage to the
boards.
Environmental Requirements
The Two Condenser Head Pressure 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 Module is housed in a plastic en-
closure. 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).
