• Do not exceed ratings of the device(s).

• The thermostat is not designed for service in any location where condensation may

occur. Avoid locations where excessive moisture, corrosive fumes, or vibration is

present. NEMA Type 1 covers are intended for indoor use primarily to provide a degree

of protection against contact with the enclosed equipment.

• Thermostats with guards that restrict air flow must have heating or cooling anticipation.

Mounting

The thermostat requires upright mounting on a flat vertical surface. Locate the thermostat

where it is exposed to unrestricted circulation of air which represents the average tempera-

ture of the controlled space.

1. Pull all wires from source to thermostat location.

2. Make electrical connection to thermostat (see Figure-2 through Figure-4).

3. Remove thermostat cover and fasten thermostat to box or wall (see Figure-5).

4. Attach thermostat cover (see Figure-5).

CHECKOUT

After installing a thermostat, make an initial check of the switching action. Verify the switch

action by listening to and watching the switch contacts or by using a voltmeter between the

proper sides of the switch.

1. Run the setpoint dial to a temperature above ambient. This should cause the thermostat

to make a circuit between the orange and brown leads.

2. Slowly turn the setpoint dial setting to a lower temperature. This breaks the circuit

between the orange and brown leads. The contact blade is in a neutral position between

the two contacts (not making a circuit to either contact). Turn the setpoint further down

to again lower the temperature. This causes the thermostat to make a circuit between

the orange and red leads.

CALIBRATION

All thermostats are calibrated at the factory and normally do not require any such attention.

However, if recalibration is necessary for any reason, proceed as follows:

W A R N I N G

Turn Off control power and power to night depression circuit, where applicable.

1. Set temperature dial 2°F (1°C) below actual stable room temperature, as read from an

accurate thermometer.

2. Remove cover (see Figure-5).
