THIS PROCEDURE MUST BE PERFORMED BY A QUALIFIED TECHNICIAN.
IMPORTANT
If connecting to the Steffes power line carrier (PLC) system, follow the installation instructions in the PLC systems Owner’s and Installer’s manual.
Installation Methods:
-
Hard wired to system to the "OS" and "SC" terminals. (See Figure 22)
OR
-
Connected to Power Line Carrier (PLC)
Figure 22
Theory Of Operation:
The outdoor sensor monitors outdoor temperature and provides this information to Serenity. Serenity responds by automatically storing heat in its brick core according to outdoor temperature and the heating requirements.
Location Of:
The outdoor sensor must be placed in a location where it can accurately sense outdoor temperature and is not affected by direct sunlight or other sources of heat or cool.
Wiring:
- Route low voltage wire from the outdoor sensor to the electrical compartment through one of the low voltage wire knockouts.
- Connect to the two terminals labeled "outdoor sensor".
- If the sensor wiring is routed through an external wall, the opening through which the wire is routed MUST be sealed. Failure to do so may affect the accuracy of the outdoor temperature sensor.
- The outdoor sensor is supplied with a lead length of 40 ft. If a greater wire length is needed, it can be extended to a total of 250 ft.
- No other loads can be controlled or supplied through this cable. It is for connection of the outdoor sensor ONLY.
- This low voltage cable MUST not enter any line voltage enclosure.
- Unshielded Class II (thermostat) wire can be used as extension wire provided it is segregated from any line voltage cabling.
