Zone Valve(s): The TZV's are factory set to maintain a loop temperature of 110°F. Temperature adjustments can be

made in approx. 5°F increments/decrements by rotating the TZV stem one full turn CCW or CW respectively. Be sure to

allow enough time for the loop to change temperature and stabilize before readjusting. If recirculation pump deadheading

is a concern, it is recommended to add a pump bypass valve or to manually adjust the TZV in the longest loop/zone to full

hot. This can later be adjusted to a lower temperature as the system stabilizes and reaches an equilibrium point.
