FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE
INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY
AND/OR PROPERTY DAMAGE.
SureSwitch™ is an electronically-controlled relay that can be used
to replace single and two-pole contactors commonly used in air
conditioners, heat pumps and other applications. A patented switching
algorithm reduces arcing between contacts, which nearly eliminates
pitting and welding for a longer life. The switching mechanism is sealed
to prevent intrusion from insects and other debris.
SureSwitch also provides advanced features for HVAC troubleshooting
and system reliability:
• Line-Voltage Brownout Protection
• Short Cycle Protection
• Random Start Delay
• Lifetime Cycle Count
SureSwitch is similar to a 1

compressor terminal C is switched. The compressor terminal R is
connected by a shorting bar to line input L1, and is energized even
when a call is not present.
Installation should be done by a qualified heating and air conditioning
contractor or licensed electrician.
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.
Following installation or replacement, follow manufacturer's
recommended installation/service instructions to ensure proper
operation.
SureSwitch has no user serviceable parts. Replace as a unit.
