PROGRAMMING TIPS
1. Determine piping arrangement and mode number
as depicted on pages 5 through 7.
2. Install system sensor and air sensor (for Mode 5
only) as positioned in the mode arrangements
located on page 6.
3. Wire the sensors to the Controller as described in
Fig. 22 on page 17.
4. Ensure that entire system is ready to start.
a. Water piping properly filled and purged.
b. Gas pipe properly installed and purged.
c. Electrical connections properly installed in
conduit.
d. Vent properly installed and terminated.
e. Sensor wires properly routed in separate con-
duit.
5. Turn on heater power to allow programming the
Controller.
6. After piping mode has been determined, program
Controller as described on pages 5 to 7.
Remember that the "Item", " " & "▼" buttons (all
three) must be pressed simultaneously for one
second to enter the program mode.
7. Use mode settings as a guide to set up the
Controller. Your settings may differ from the values
given in the manual depending upon the tempera-
ture settings required.
8. After programming Controller, the settings will be
automatically saved after 20 seconds of keypad
inactivity.
9. If the Controller display indicates any error(s), turn
to page 32 to identify and correct the error(s) that
are displayed.
