verifies that the blower vacuum switch contacts are open before energizing the blower.

3. It is normal for the heater to display up to a 5-second delay when the keypad is used to reset the con
-
trol to clear an error code.
4. The control will accept a mode change during lockout after 5 seconds. The control will continue to
display the error code and remain in lockout until it is reset. At reset the control will go to the last
saved mode.

WINTERIzATION:
In moderate climates, the heater can continue to operate during short-term cold spells. Do not use the
heater to maintain the water temperature just above freezing or for freeze protection. Care must be taken to
avoid freeze-up in the heater. When it is used during freezing weather, the pump must run continuously. The
heater is not warranted against freeze-ups. In regions where freezing temperatures are encountered, all water
must be drained from the heater when it is out of service, to prevent damage to the heater and piping. Drain

ing the heat exchanger is recommended as part of the season’s shutdown procedures.
