FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY

BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE

PERSONAL INJURY AND/OR PROPERTY DAMAGE.

DESCRIPTION

Operator: Save these instructions for future use!

The Type 1050 Indoor-Outdoor Control is designed for use on

conventional hot water heating systems where it is desired to

vary boiler temperature according to outdoor weather condi-

tions. These controls are not recommended for radiant panel

installations because of the lower boiler temperatures required.

Type 1050 has open-on-rise (SPST) switch action.

This indoor-outdoor control increases or decreases frequency

of burner operation to maintain a proper balance between boiler

temperature and outdoor temperature. This control should

always be used with a separate high limit control.

For increased flexibility, this control has two simple adjustments

that enable it to be set to meet the needs of almost any

installation. The square dial is used to adjust the reset ratio from

1-1/2 to 1, up to 1 to 1-1/2. The round dial permits additional

adjustment, if necessary, to raise or lower boiler water tempera-

ture at all outdoor temperatures.

INSTALLATION INSTRUCTIONS

TYPE 1050

INDOOR - OUTDOOR

HOT WATER TEMPERATURE CONTROL

With Adjustable Reset Ratio

THIS CONTROL 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 compo-

nents 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.

PRECAUTIONS

WARNING

To prevent electrical shock and/or equipment

damage, disconnect electric power to system at

main fuse or circuit breaker box until installation

is complete.

Do not use on circuits exceeding specified volt-

ages. Higher voltages will damage control and

could cause shock or fire hazard.

INSTALLATION Both the outdoor bulb and inside bulb should be installed before the control case, since capillary lengths of these bulbs will normally determine the final location for the control case. NOTE Use care not to bend or dent either of the sensing bulbs ROOF A. INSTALLING THE OUTDOOR BULB: Locate the outdoor bulb so that it senses actual outdoor air temperature. Attach mounting bracket supplied with control to some convenient outside part of the building so that the outdoor bulb is: 1.

DIAL SETTINGS When using this control as an exact replacement, use same dial settings as for old control. A. SETTING THE ROUND DIAL: Set the round dial for “N” initially. This will enable minor additional adjustments to be made later if the specific installation should require it (refer to “C”.) B. SETTING THE SQUARE DIAL: Select the proper square dial setting from table 1 or 2 below.

DIAL SETTINGS CONT. D. ADDITIONAL INFORMATION: Charts 1, 2, and 3 show the effect which dial settings have upon boiler water temperature under varying outside air temperatures. Some examples of how these charts may be used are as follows: 4 (104) 220 Example 1 (See Chart 1) – To determine boiler water temperature for 10° outside air temperature and a #3 square dial setting, move up on 10° line until it intersects the heavy line for a #3 square dial setting.
