WHITE RODGERS Fan Coil Heating Cooling Thermostat Instruction Manual
DESCRIPTION
The 1A 11-2 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 milli volt, line, or low voltage, have it inspected by a qualified heating and air conditioning contractor, electrician, or someone familiar 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 components could cause the control to malfunction.
CAUTIONTo prevent electrical shock and/or equipment damage, disconnect electric power to system, at main fuse or circuit breaker box, until installation is complete.CAUTIONDo not use on circuits exceeding specified volt-age. Higher voltage will damage control could cause shock or fire hazard.
Specification
Switch Action: SPDT (Heating – open on rise) (Cooling – close on rise)Temperature Range: 36°F to 90°F (2°C to 32°C)CAUTIONWhen the thermostat is set below 40°F (5°C), damage to the building and/or contents may result due to freezing. This is possible due to factory calibration tolerances, thermostat location and operating characteristics of the heating equipment.
System Switch: Heat – Off – Cool
Fan Switch : Low – Medium – High

INSTALLATION
Proper location insures that the thermostat will provide a comfortable home temperature. Observe the following general rules when selecting a location:
- Locate thermostat about 5 ft. above the floor
- Install thermostat on a partitioning wall, not on an outside wall.
- Never expose thermostat to direct light from lamps, sun, fireplaces or any temperature radiating equipment.
- Avoid locations close to windows, adjoining outside walls, or doors that lead outside.
- Avoid locations close to air registers or in the direct path of air from them.
- Make sure there are no pipes or duct work in that part of the wall chosen for the thermostat location.
- Never locate thermostat in a room that is warmer or cooler than the rest of the home, such as the kitchen.
- Avoid locations with poor air circulation, such as behind doors or in alcoves.
- The living or dining room is normally a good location, provided there is no cooking range or refrigerator on opposite side of wall.
INSTALL THERMOSTAT
CAUTIONTo prevent electrical shock and/or equipment damage, disconnect electric power to system at main fuse or circuit breaker box until installation is complete.The thermostat may be mounted on a standard 2 x 4 inch vertical outlet box or 2-ganged outlet boxes. When mounting to a 4 x 4 inch junction box is required, use of a standard adapter plate (not provided) is necessary. USE COPPER CONDUCTORS ONLY.Install the thermostat as follows:
- Before mounting, connect system wiring to proper color-codedleads at rear of thermostat. Follow equipment manufacturer’s instructions or refer to wiring diagram for typical system hookups.
- Remove thermostat cover by grasping top and bottom of cover and pull straight out. Dress wiring into junction box and secure thermostat to outlet box with mounting screws.NOTE: DO NOT PUSH OR DAMAGE THE TEMPERATURE KNOB DURING INSTALLATION.
- Install thermostat cover, turn knob to desired set-ting, and set selector switches for the appropriate system function and fan speed.
WIRING
CAUTIONTo prevent electrical shock and/or equipment damage, disconnect electric power to system at main fuse or circuit breaker box until installation is complete.Varying the wiring can alter the thermostat/system operation as shown below:
- For the thermostat to cycle both fan and valve, connect all wires as shown.
- For the thermostat to cycle fan only (if valve is not used), do not connect the thermostat orange wire to the system. Wrap orange lead with approved electrical tape or wire nut to prevent shorting.
- For the thermostat to cycle the valve only (with fan on continuously), Connect orange wire to L1 and black wire to VALVE. Connect all other wires as shown.
NOTE:With the system switch in the OFF position, the thermostat will prevent both the fan and valve circuits from turning on.
NOTEThis typical wiring diagram shows only the terminal identification and wiring hookup. Always refer to wiring instructions, provided by equipment manufacturer, for system hookup operation. All wiring should be done according to local and national electrical codes and ordinances.
Note:Above FAN and SYSTEM switches shown in MED and HEAT positions respectively.
