BT1-1030 Coyote Control Knob

The BT1-1030 Coyote Control Knob is used on compatible mobile HVAC control panels.
It is designed as a push-on style knob for a 1/4 inch shaft.

This knob may fit the same applications as several common HVAC control knob interchange numbers.
However, the appearance may vary from the original knob.

As a result, it is a useful replacement option when function and shaft fit are more important than exact cosmetic match.

Function and Performance

A control knob gives the operator a simple way to adjust an HVAC control.
This knob is used with compatible thermostatic switch applications.

The BT1-1030 is a push type knob.
It presses onto a 1/4 inch shaft without a set screw.

In addition, this knob features a snowflake indicator.
That makes it useful for A/C or cooling-related control positions.

Durability and Design

The BT1-1030 control knob is designed for mobile HVAC use.
Cab HVAC controls often face repeated use, vibration, temperature changes, and normal wear.

This knob is made for push-on installation.
Therefore, the shaft size and shape must match before installation.

Because appearance can vary between interchange versions, compare the knob style if visual match is important.

Installation

Install this knob by aligning it with the control shaft.
Then press it onto the shaft until it seats securely.

Before installation, confirm the shaft size, switch model, and knob orientation.
Do not force the knob if the shaft does not match.

Also verify that the indicator position matches the function of the HVAC control.
