4.3 0 TO 10 VOLT REMOTE SET POINT MODE
This mode allows the boiler set point to be controlled by an external control signal. The following
paragraphs provide the procedures necessary to wire, configure and set the required functions
necessary to operate in the 0 to 10 volt remote set point mode.
4.3.1 Remote Signal Source Wiring Connections
When setting up to operate in the 0 to 10 volt remote setpoint mode, the remote signal source must be
wired to terminals 1 (F-15) and 2 (GND) of connector number 3 (
III
) on the rear of the Controller. See
Section 5 for illustrations and pinouts of the connectors located on the rear of the Controller.
4.3.2 Configuring the Controller
Configure the Controller as follows:
1. Set the
ON/OFF
switch on the front of the Modulex boiler to the
ON
position.
2. Open the swing-down hinged panel of the Controller.
3. Turn the Rotary Knob clockwise to the EXPERT menu. The first item (sub-menu) displayed will be
INSTALLATION (the sub-menu items will scroll in the following sequence: INSTALLATION, HOT
WATER, HEAT CIRCUIT 1, HEAT CIRCUIT 2, SOLAR / MF). Continue scrolling (clockwise)
through the EXPERT menu until SOLAR / MF is displayed.
NOTE
If you scroll past the SOLAR / MF item, the EXPERT HS menu will be displayed. If this
occurs, slowly turn the Rotary Knob counterclockwise until SOLAR / MF is again
displayed.
4. With SOLAR / MF displayed, press the Program Key to enter the SOLAR / MF sub-menu.
5. Scroll through the SOLAR / MF sub-menu by turning the Rotary Knob clockwise until the F-15
Function is displayed along with
it’s presently stored value ( default is 00).
6. Press the Program Key to change the F-15 Function. The display will show CODE NO., requesting
the valid code to be entered.
7. Enter code 0000 (4 zeros) by pressing the Program Key four times. The red LED will remain lit
while the four code digits are entered.
8. With F-15 Function again displayed and the red LED lit, turn the Rotary Knob to change the F-15
Function to 01.
9. Press the Program Key to store the 01 setting for the F15 Function. The red LED will go off.
10. Continue scrolling through the sub-menu until RETURN is displayed.
11. Press the Program Key to exit the SOLAR / MF sub-menu.
12. With SOLAR / MF displayed, turn the Rotary Knob counterclockwise until the INSTALLATION sub-
menu item is displayed. Turning the Rotary Knob counterclockwise will help minimize scrolling and
display the sub-menu items in reverse order (i.e.:SOLAR / MF, HEAT CIRCUIT 2, HEAT CIRCUIT
1, HOT WATER, INSTALLATION).
13. With INSTALLATION displayed, proceed directly to paragraph 4.3.3.
