DESCRIPTION  
These room thermostats are specially designed to control  
combination heating and cooling equipment that operates on  
line voltage.  
These controls are suitable for fans or water solenoids on  
heating/cooling convectors or any similar application that re-  
quires a heavy duty room thermostat with single pole, double  
throw (SPDT) switch action.

PRECAUTIONS  
CAUTION  
NOTE  
!
If in doubt about whether your wiring is millivolt, line, or low  
voltage, have it inspected by a qualified heating and air condi-  
tioning contractor or electrician.  
To prevent electrical shock and/or equipment damage  
disconnect electric power to system at main fuse or  
circuit breaker box until installation is complete.  
Do not exceed the specification ratings.  
Label all wires prior to disconnection when servicing  
controls. Wiring errors can cause improper and dan-  
gerous operation.  
Allwiringmustconformtolocalandnationalelectricalcodesand  
ordinances.  
This control is a precision instrument, and should be handled  
carefully. Roughhandlingordistortingcomponentscouldcause  
the control to malfunction.  
Following installation or replacement, follow appli-  
ance manufacturer’s recommended installation and/  
or service instructions to insure proper operation.  
This control has been accurately calibrated at the factory. Any  
attempt to calibrate this control will void the White-Rodgers  
warranty.  
WARNING  
!
Do not use on circuits exceeding specified voltage.  
Higher voltage will damage control and could cause  
shock or fire hazard.

THERMOSTAT LOCATION  
Proper location of the heavy duty room thermostat is very  
important to insure acceptable performance. The following  
general rules will help determine proper location:  
Concrete  
Plaster/  
Drywall  
Junction Box  
1. It is very important to be sure that the thermostat is in an  
area where air circulates around it freely.  
2. Never install the thermostat on or near an outside wall.  
3. Donotlocatethethermostatnearwindowsordoors,orinany  
drafty area.  
Themostat  
Conduit  
4. Don’t install the thermostat where it will be affected by “false”  
heat sources (such as direct sunlight, a stove or any appli-  
ance exhaust, steam lines, etc.).

5. Mount the thermostat on a post or a partioning wall, but be  
surethattherearenopipes, ductworkorheatsourcesinthat  
wall or directly behind it.  
WALL INSTALLATION  
The mounting plate for this thermostat has two  
holes 35/16”apart for attaching the control on a  
standard switch box.  
6. If the electrical conduit leads into a cooler or warmer room,

prevent drafts.

If the thermostat is used with unit heaters, the following sugges-  
tions for locating the thermostat may be helpful (see fig. 2).  
Post  
1. Position A in fig. 2 is acceptable if the thermostat is close  
enough to the unit heater so that the return air to the heater  
flows over the thermostat.  
Partition wall  
or post directly  
behind unit  
Unit  
B
2. Position B is acceptable if it is not necessary to make  
frequent adjustments of the dial setting.  
3. Position C is acceptable if it is sufficiently far from the heater  
that air flowing over the thermostat is not much above the  
average room temperature.

4. Position D is not acceptable because the post may prevent

air from circulating over the thermostat.

WIRING  
All wiring should be done in accordance with local and national electrical codes and ordinances.  
Follow the wiring instructions provided by the heating/cooling  
equipment manufacturer. If none are offered, a typical circuit  
application is shown at right.
