provide precise temperature control. This thermostat of-
fers you the flexibility to set heating and cooling tempera-
tures that fit your needs.
Features:
• Simultaneous heat and cool temperature storage
• LCD continuously displays set point and room tem-
perature
This thermostat is intended for use with a 24-volt system;
do not use this thermostat with a millivolt or line voltage
system. If in doubt about whether your wiring is millivolt,
line, or low voltage, have it inspected by a qualified
heating and air conditioning contractor or 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 compo-
nents could cause the control to malfunction.
