Hot Water Controls

Remote Type

INSTALLATION INSTRUCTIONS

If the equipment manufacturer recommends a control location,
follow such recommendations. If none is offered, the following
recommendations should be observed.

When used to control the temperature of a vat or tank, locate the
control bulb in a place representative of the average tempera-
ture. Make certain that the fluid being controlled is not injurious
to the copper element.

When used for high limit service on a heating boiler, 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 in that 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.

Be careful to avoid damage to the capillary tubing between the
control and the temperature sensitive bulb. This tubing should
be led over a path that will protect it from cuts, blows, wear due
to vibration, etc.

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.

These hot water controls were designed for use on hot water
heating installations but they may be used on other heating
applications to control the temperature of other fluids. The fluid
they are to be used with must not be corrosive to copper.

These controls have capillary tubing between the temperature
sensitive bulb and the switch mechanism so that the switch
mechanism can be mounted at any convenient location while
the temperature sensitive bulb is located in the fluid to be
controlled.

These controls have special contacts which are suitable for use
on low voltage and millivolt (thermocouple generator type)
circuits as well as line voltage equipment such as gas valves, oil
burner motors, etc.

DESCRIPTION

PRECAUTIONS

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.

WARNING

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

CAUTION

Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dan-
gerous operation.

Following installation or replacement, follow appliance
manufacturer's recommended installation and/or ser-
vice instructions to insure proper operation.

CAUTION

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

Shut off main gas to heating system until installation is
complete.

CAUTION

Do not dent or bend the bulb as this will change the
control calibration and cause it to cycle at a tempera-
ture lower than the dial setting.

INSTALLATION

Operator: Save these instructions for future use!
