INSTALLATION INSTRUCTIONS

High Limit Control
Open On Rise, Manual Reset
This high limit control is of the non-cycling manual reset
type; once the contacts open, they will remain open until
the reset button is pushed.
This control is designed to break a line voltage (or low
voltage) circuit if air temperature at its element location
ever reaches its predetermined cut-out setting.
This control may be used to protect against high tempera-
tures in heating and ventilation systems by opening circuit
to burner if circulated air reaches a temperature above the
fixed setting of the control. It is also suitable for use on
downflow furnaces to lock out burner in event of blower
failure or slow start.
Follow any wiring instructions provided by the furnace
manufacturer. Typical diagram is shown for normal use of
this control. A normal cycling type high limit control should
always be used in addition to the High Limit Control for
monitoring burner operation.
All wiring should be installed according to local and
national electrical codes and ordinances. Controls
are required to be installed with 75
°
C minimum wire.
This control has a fixed setting. If temperature ever reaches the cut-out setting, the contacts will open. When
temperature drops to safe level, the reset button must be pushed before contacts will reclose.
