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

INSTALLATION INSTRUCTIONS
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.
