Troubleshooting
!
Always use proper precautions when accessing circuit breaker box.
Problem:
Solution:
Outlet temperature is below set point temperature and/or the low tem-
perature alarm has been activated
1. Depending on the heating plant plumbing and location, it may take several minutes for the hot water to
reach the unit. Ensure that you have allowed enough time (5 minutes) for the system to come up to tem-
perature.
2. On the Home screen, check the “Mixed Outlet Set point” and the hot water supply temperature. The hot
water supply temperature needs to be above the set-point or the unit will not be able to reach the set-
point.
3. If the hot water supply temperature is BELOW the “Mixed Outlet Set point”
a. Raise the hot water supply temperature at least 2F (1C) above the mixed outlet set-point temperature.
b. Ensure that the hot water is flowing.
c. Check the hot water source set-point temperature and ensure that the hot supply line has no obstruc-
tions or closed valves restricting flow to the IntelliStation.
4. If the hot water supply temperature is ABOVE the “Mixed Outlet Set point”, there are no obstructions
preventing hot water from reaching the unit, and there is sufficient flow through the unit, reset the control
by pressing the PRGM icon to access the “Programming” menu. Unlock the control and then select the
“Toolbox” to navigate to the “Toolbox” menu. From within the “Toolbox” menu use down arrow to high-
light “Reset” then press enter. This will access “Reset” menu. Press the “YES” and then press accept. The
controller will reset and begin a start up sequence.
Note: Alternately, the control can be reset by opening and closing the circuit breaker switch and waiting 100
seconds to resume normal operation.
6. If problem persists after conducting the above outlined problem solving procedures, contact Powers,
Technical Support at 800-669-5430 or [e-mail].
