Installation & Wiring
Power Supply
The Water Source Heat Pump Module requires a 24 VAC power con-
nection with an appropriate VA rating.
If you will be connecting the Water Source Heat Pump Module to the
VCM-X WSHP Controller or SA Controller, one of the most important
checks to make before powering up the system for the fi rst time is to
make sure that the VCM-X WSHP Controller or SA Controller is con-
fi gured properly for your application. Refer to the VCM-X Controller
Technical Guide or SA 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 Water Source Heat Pump Module needs to be installed in an environ-
ment that can maintain a temperature range between -30°F and 150°F
and not exceed 90% RH levels (non-condensing).
Mounting
The Water Source Heat Pump 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 mounting the module.
See Figure 2 for Module dimensions (dimensions are in inches).
