OT18-60A OUTDOOR THERMOSTAT 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 precautions and related items.
Prior to actual installation, thoroughly familiarize yourself with this Instruction Manual. Pay special attention to all safety warnings. 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 before 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 adjustable 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 Thermostat must be installed and set at (0º F) on the dial. Failure to comply wth this requirement may result in damage to the product 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 increment 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 connections.

1.Remove the sheet metal screws securing the unit control box cover.
2.Install the OT18-60A Outside Thermostat using the supplied bracket and self-drilling screws (see Figures 3 through 9.). NOTE: Early split, packaged cooling and heat pump units, refer to Figures 3 through 6. AS*, D*, GS* and SS* split cooling and heat pump units, refer to Figures 7 and
8.AP*, GP*, DP* packaged cooling and heat pump units, refer to Figure 9.
3.Wire the thermostat per Figures 10, 11, 12, 13, 14, and
4.Route the capillary away from live terminals to prevent electrical shorts.
NOTE: Outdoor Thermostat copper capillary will remain inside of the control box on early models. On AS*, D*, GS*, SS*, AP*, GP* and DP* models, the capillary will extend outside the control box.
5.Set installed thermostat(s) to the proper outdoor temperature. Insert a screwdriver in slot of thermostat dial (Figure 1). Turn set point indicator as shown in figure to desired temperature setting on label (counterclockwise for WARM, clockwise for COLD).
6.Reinstall the control box cover.
