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

DESCRIPTION

The 1A11-2 thermostat controls line voltage valves and/ or blower motors on fan coil units in manual changeover, heating/cooling systems. It features a system switch for manual selection of heat -off-cool, a three speed manual fan control switch, an adjustable temperature dial with a 36 to 90°F range, and an indicating thermometer, all combined in one deluxe-styled control.

Color-coded leads are provided for connection to field wiring. The thermostat can be wired to perform the following functions:

-Thermostat cycles both fan and valve.

-Thermostat cycles fan only.

-Thermostat cycles valve only.

-System switch “OFF” breaks all circuits.

PRECAUTIONS

If in doubt about whether your wiring is millivolt, line, or low voltage, have it inspected by a qualified heating and air conditioning contractor, electrician, or someone famil- iar with basic electricity and wiring.

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.

!CAUTION

To prevent electrical shock and/or equipment damage, disconnect electric power to system, at main fuse or circuit breaker box, until installa- tion is complete.

!WARNING

Do not use on circuits exceeding specified volt- age. Higher voltage will damage control - could cause shock or fire hazard.
