Testing:
Run the system and pay close attention to the radiant surface temperatures and dew
point (see next page diagram) where unwanted condensation may occur and look for
any condensation. There should be no wetness at all. Temperatures should agree with
your projections within 1-2 degrees F, adjust as needed. Monitor this closely at various
temperatures and conditions after initial startup, until you are sure your settings are
sufficient.
Problem: Valve does not operate upon start up
Solution: Make sure your power wires are plugged in, if the controller LCD is not lit up
then the valve does not have power. Upon start up the valve will start at full
recirculation and then it will begin to modulate.
Problem: Valve is moving too much, too fast, too far, etc.
Solution: This is not exactly as it appears. This valve uses a gear reduction motor so the
valve manual positioner that you can see may appear to move a very large amount,
note that even an apparent full turn of the valve is only a small change to the actual
amount of in mixing/non-mixing adjustment applied.
Problem: I am getting unexpected condensation
Solution: Check your calculations for error, or there may be an error in your R-value
assumptions. If this cannot be corrected with adjustments on your own, please contact
Chiltrix technical support (advanced support dept.).
