Boiler Control SC-9 - Nine Stage Boiler & Setpoint
SC-9
The installer must ensure that this control and its wiring are isolated and/or shielded from strong sources of electromagnetic noise.
Conversely, this Class B digital apparatus complies with Part 15 of the FCC Rules and meets all requirements of the Canadian
Interference-Causing Equipment Regulations. However, if this control does cause harmful interference to radio or television reception,
which is determined by turning the control off and on, the user is encouraged to try to correct the interference by re-orientating or relo-
cating the receiving antenna, relocating the receiver with respect to this control, and/or connecting the control to a different circuit from
that to which the receiver is connected.
Caution: The nonmetallic enclosure does not provide grounding between conduit connections. Use grounding type bush-
ings and jumper wires.
