INSTALLATION INSTRUCTIONS

DESCRIPTION

THESE CONTROLS MUST BE INSTALLED BY A QUALIFIED
INSTALLER.

Do not exceed the specification ratings.
All wiring must conform to local and national electrical codes

and ordinances.
This control is a precision instrument, and should be handled

carefully. Rough handling or distorting components could cause
the control to malfunction.

This control has been accurately calibrated at the factory. Any
attempt to calibrate this control will void the White-Rodgers
warranty.

If the boiler manufacturer recommends a control location, follow
such recommendations. If none is offered, the following informa­tion gives suggested locations.

When used for high limit service, the control should be in­stalled in the riser close to the boiler, or in a boiler tapping that
is near the top or hottest section of the boiler. If the boiler is also
used to heat domestic hot water, make sure that the high limit
control is not located in the section of the boiler that contains the
heat exchanger or piping for domestic hot water.

When used for low limit or operator service, the control should
be located near that section of the boiler that contains the heat
exchanger or piping for domestic hot water.

PRECAUTIONS

To prevent electrical shock and/or equipment dam­age, disconnect electric power to system, at main fuse
or circuit breaker box, until installation is complete.

WARNING

Do not use on circuits exceeding specified voltages.
Higher voltages will damage control and could cause
shock or fire hazard.

INSTALLATION

To remove the well from the control, loosen the set screw in the
large nut, then slide the well off to expose the bulb. Screw the
well into the proper tapping. Slide the bulb back into the well,
making sure that the bulb enters the well as far as it will go and
tighten the set screw.

CAUTION

Do not dent or bend the bulb as this will prevent it from
fitting into the well properly.

SETTING THE CONTROL

CONTROLS WITH ADJUSTABLE DIFFERENTIAL

1. Insert a screwdriver in the centre slot and turn the dial until
the right hand indicator “B” points to the lowest temperature
of the cycle.

2. Turn the differential adjusting screw “C” until the left hand
indicator “D” points to the highest temperature of the cycle.

The left-hand indicator points to the temperature at which the
contacts open on high limit and low limit applications. On
circulator applications, the left-hand indicator points to the
temperature at which the circulator will start.

On combination low limit and circulator applications, the
left-hand indicator points to the temperature at which the low
limit stops the burner and permits the circulator to run.

CONTROLS WITH FIXED DIFFERENTIAL

Insert a screwdriver in centre slot “A” and turn the dial until the

the cycle.

The fixed indicator points to the temperature at which the
contacts open on high limit and low limit applications. On
circulator applications, the fixed indicator points to the tem­perature at which the circulator will start.

On combination low limit and circulator applications, the
fixed indicator points to the temperature at which the low limit
stops the burner and permits the circulator to run.
