Programming Steps and Display
The ETC can be programmed in four simple steps using the LCD display and the three keys on the face
of the control.
Step 1 - To start programming, press the SET key once to access the Fahrenheit/Celsius
mode. The display will show the current status, either F for degrees Fahrenheit or
C for degrees Celsius. Then press either the up
⇑ or down ⇓ arrow key to toggle
between the F or C designation
Step 2 - Press the SET key again to access the setpoint. The LCD will display the current
setpoint and the S1 annunciator will be blinking on and off to indicate that the
control is in the setpoint mode. Then press either the up
⇑ key to increase or the
down
⇓ key to decrease the differential to the desired temperature.
Step 3 - Press the SET key again to access the differential. The LCD will display the
current differential and the DIF1 annunciator will be blinking on and off to indicate
that the control is in the differential mode. Then press either the up
⇑ or the down
⇓ key to decrease the differential to the desired setting.
Step 4 - Press the SET key again to access the cooling or heating mode. The LCD will
display the current mode, either C1 for cooling or H1 for heating. Then either
press the up
⇑ or down ⇓ key to toggle between the C1 or H1 designation. Press
the SET key once more and programming is complete.
Note: The ETC will automatically end programming if no keys are depressed for a period of thirty
seconds. Any settings that have been input to the control will be accepted at that point .
