White-Rodgers 49S25-707 Directives D'installation

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
The 49S25-707 is a Two-Stage unitary air conditioning or heat
pump control designed for applications with PSC or ECM outdoor
fan motors and single-phase compressors up to 5-ton units. This
control is designed to work as part of a fully communicating
HVAC system using 4 wires or legacy 24 VAC inputs to support
non-communicating systems.

CAUTION
!
Risk of Electric Shock.
Disconnect electric power
to system until installation
is complete. Do not use on
circuit exceeding specified
voltage. Higher voltage will
damage control and could
cause shock or fire hazard.
This control is not intended
for use in locations where
it may come in contact with
water.
May cause flame rollout.
Shut off main gas to heat-
ing system until installa-
tion is complete.
