INSTALLATION INSTRUCTIONS

ATTENTION INSTALLING PERSONNEL

As a professional installer you have an obligation to know the

product better than the customer. This includes all safety pre-

cautions and related items.

Prior to actual installation, thoroughly familiarize yourself with

this Instruction Manual. Pay special attention to all safety warn-

ings. Often during installation or repair it is possible to place

yourself in a position which is more hazardous than when the

unit is in operation.

Remember, it is your responsibility to install the product safely

and to know it well enough to be able to instruct a customer in

its safe use.

Safety is a matter of common sense...a matter of thinking be-

fore acting. Most dealers have a list of specific good safety

practices...follow them.

The precautions listed in this Installation Manual are intended

as supplemental to existing practices. However, if there is a

direct conflict between existing practices and the content of

this manual, the precautions listed here take precedence.

DESCRIPTION

This single pole double throw thermostat device with adjust-

able 0° to 45° temperature range is employed in conjunction

with the room thermostat to control the electric heaters that

have been added to cooling and heat pump products. This kit

includes an Outdoor Thermostat, three wires, mounting bracket,

(3) wire caps, and (2) self-drilling screws.

Note: If the outdoor ambient temperature is below 0° F (-18°

C) with 50% or higher Relative Humidity, an Outdoor Thermo-

stat must be installed and set at (0º F) on the dial. Failure to

comply wth this requirement may result in damage to the prod-

uct which may not be covered by the manufacturer’s warranty.

See Figures 12 and 15 for wiring connections.

The schematic and the terminal view of this device is shown in

Figure 2:

When used as an outdoor thermostat to control increments of

electric heat, connections will be made to terminals 2 and 1.

As temperature rises above the set point contacts 2 to 1 will

open thus preventing the controlled increment of supplemental

heat from operating. As outdoor temperature falls below the

set point contacts 2 to 1 will close allowing the controlled in-

crement of heat to operate. See Figures 10, 11, 13, and 14 for

wiring connections.

Use the wires supplied for Outdoor Thermostat connections. If

the installation is with an All Fuel kit, refer to the Installation

Instructions supplied with the AFE18 All Fuel kit for wiring con-

nections.

INSTALLATION

The outdoor thermostat is designed to be installed in the space

allocated in the control box of the cooling and heat pump units.
