WARNING

To prevent overheating or fire, use this control as an operating or regulating

thermostat. ALWAYS USE A BACKUP CONTROL OR ALARM if a control

failure could cause the controlled appliance to overheat or could cause a fire

Where thermostat is capable of cycling directly between heating and cooling

loads, failure to provide a load transfer switch will result in thermostat failure.

Do not install, use or operate if product appears damaged, the enclosure is

cracked or broken or if the sensor has been bent, crimped or is dirty.

APPROPRIATE APPLICATION

This thermostat has been tested by CSA and Underwriters Laboratories Inc.

(UL), meets the requirements for NEMA 4X equipment and is suitable for use

under the National Electrical Code (NEC), Article 547-7, when used with

appropriate watertight connectors (not included).

INSTALLATION

Installation must be made by a trained, qualified service person in accordance

with the National Electrical Code (NEC) and all applicable local codes and

ordinances. Installation should meet all applicable national, state and local

codes. Refer to the appropriate wiring diagram included. Locate the thermostat

( local sensing models ) or sensing bulb ( remote sensing models ) for optimum

temperature sensing of the controlled space. Thermostat operation will be

affected by unusual heat or cold, such as direct sunlight, near windows or doors

or on outside walls.

All fittings and materials used for the installation should be approved, suitable

and installed properly for the intended application. For water tightness, the cord

seal or conduit hub should be UL listed and marked 4X. The conduit hub is to be

tightened onto the conduit before installing in the enclosure.

Where applicable, remove knockout(s) by impacting near the inside edge of the

knockout to be removed. IMPORTANT: Do not impact, dent or use the

sensor for support. This will cause calibration and/or thermostat failure.

To avoid electrical shock or damage to equipment, disconnect all power

before installing or servicing.

To avoid potential fire and/or explosion, do not use in potentially flammable or

explosive atmospheres.

WARNING

WARNING

READ

INSTRUCTION

CAREFULLY

BEFORE

ATTEMPTING

TO

INSTALL, OPERATE OR SERVICE THIS THERMOSTAT.

Failure to

observe safety information and comply with instructions could result in

PERSONAL INJURY, DEATH AND/OR PROPERTY DAMAGE.

Retain these instructions for future reference. This product, when installed,

will be part of an engineered system whose specifications and performance

characteristics are not designed or controlled by PECO. You must review

your

application

and

national

and

local

codes

to

assure

that

your

installation will be functional and safe.

Even though this thermostat is sealed, water or dust could enter through

improperly sealed wiring. A drip loop should be provided to prevent water and

other liquids from entering the thermostat housing. The cord or conduit

connections to the enclosure must be water and dust tight. The cover must be

tightened securely to compress the gasket and provide a watertight seal. Use

only screws provided. Do not over-tighten.

Maximum sensing element withstand temperature is 35°F (20°C) above the

highest temperature setting. Maximum temperature for the plastic enclosure is

140°F 60°C.

OPERATION AND CHECK-OUT

Allow one hour or necessary amount of time for the thermostat and system to

stabilize for normal operation. This thermostat is factory calibrated and

requires no correction on site.

TO CHECK OPERATION OF HEATING SYSTEMS:

1.

Disconnect power.

2.

Place the heat/cool selector switch, if applicable, in the heat position.

3.

Adjust

the

thermostat

set

point

to

at

least

10°F

(5°C)

below

the

temperature of the controlled space.

4.

Restore power.

5.

Slowly adjust the thermostat knob to raise the set point. When the set

point reaches the approximate temperature of the controlled space, the

heating equipment should start.

TO CHECK OPERATION OF COOLING SYSTEMS:

1.

Disconnect power.

2.

Place the heat/cool selector switch, if applicable, in the cool position.

3.

Adjust the thermostat set point to at least 10°F (5°C) above the

temperature of the controlled space.

4.

Restore power.

5.

Slowly adjust the thermostat knob to lower the set point. When the set

point reaches the approximate temperature of the controlled space, the

cooling equipment should start.

For use in wet or humid environments or where water tightness is required,

failure to use suitable watertight connections and suitable drip loop could

allow water to enter the enclosure resulting in thermostat failure.

Use copper wire only. Insulate or wire-nut all unused leads.

Use the grounding provisions provided for connection to the line ground

and equipment ground wire.
