Over Temperature Protection (OTP)
The OTP will control the furnace temperaure at a preset value if
the primary control circuit fails. It is advisable to set the OTP to
either the maximum operating temperature of the furnace, or to
a value of 20 degrees above the operating temperature.
- Set OTP by pressing the ``scroll'' button until AL.SP
(Alarm Set Point) appears. The display would indicate
the previously set OTP. Press the ``up'' or ``down''
button to select a desired value of OTP.
