CHAPTER 6: E8 SETUP AND PROGRAMMING
The following sections provide the detailed set-up and programming procedures necessary to
configure the Modulex Boiler for service operation.
NOTE
When performing the following operating mode set-up procedures,
refer to Chapter 3 of this document for illustrations and
descriptions of the Controller operating controls and displays.
Refer to Chapter 6 for Controller wiring connections.
6.1 Indoor/Outdoor Reset Mode
This mode is used to adjust the boiler set point based on the outdoor air temperature and a
programmed heating curve. The heating curve can be customized using functions provided in
the USER menu. The outdoor air sensor provided with the Modulex boiler must be installed to
enable this mode of operation. The following sections provide the procedures necessary to
wire and configure the controller for operation in the Indoor/Outdoor Reset mode.
6.1.1 Wiring Connections
The outdoor air sensor provided with the boiler should be mounted on the outer North or
North-East side of the building away from windows, doors and vents. Never mount the outdoor
air sensor in a location where it is exposed to direct sunlight.
Wire the sensor using shielded 2-conductor, 18 AWG wire (Belden #8760, or equiv.). Connect
the outdoor air sensor wire leads to terminals 9 (F9) and 10 (GND) of Connector 1 on the rear
of the Controller. There is no polarity to observe when connecting the wire leads. Refer to the
wiring diagrams in Chapter 7 for the locations of sensor connections. This sensor must be
connected (Section 7.1.2) prior to configuring the Controller.
6.1.2 Indoor/Outdoor Reset Operation Configuration
The Indoor/Outdoor Reset Mode is configured using the USER menu as shown in instructions
on the next page.
IMPORTANT
The outdoor air sensor MUST be connected as described in
Section 5.1.1 above, prior to configuring the Controller for
Indoor/Outdoor Reset Mode operation.
