Troubleshooting<br />
Increase sensor response delay. See 3.12 - Calibrate Sensors.<br />
During period of low humidity, static electricity can cause the control<br />
program to freeze or display incorrect information. Although this is<br />
unlikely, the control can be reset by cycling power from the disconnect<br />
switch.<br />
Find open or short circuit and repair power to pump.<br />
Temperature display will indicate dashes. Check wiring from<br />
temperature/humidity board (remote sensors) to the control board or<br />
from control board to wallbox. Replace temperature/humidity circuit<br />
board (remote sensors) or wallbox.<br />
Check wiring and/or replace control board.
