Hired-Hand System 1000 Power Curtain Eight Stage Controller - Manual (Page 12)

System 1000™ Power Curtain™ Controller 9
important because the design of the controller prevents a cool stage from running while
a heat stage is active (and vis versa).
The Sensors for display feature lets you choose which sensors will show up on the screen
during normal operation. You may select any combination of sensors one, two, and
three. (Sensor four is for outside sensor control).
8. Offset and Differential
8.1. Offset:
The point above (cool) or below (heat) target temperature where the stage turns off.
8.2. Differential:
The difference in degrees between the temperature a stage comes on and the temperature
the stage goes off.
8.3. Examples
8.3.1. Heat Mode:
If the Target Temp is set at 80 degrees, Offset set at 4 degrees, and Differential set at 2
degrees, The System will engage Heat Mode when building temperature reaches 74
degrees and the curtains are closed.
Example: Target Temp - Offset - Differential = Heat Mode on
80 - 4 - 2 = 74
If the Target Temp is set at 80 degrees, Offset at 4 degrees and Differential set at 2
degrees, The System will disengage Heat Mode when building temperature reaches 76
degrees.
Example: Target Temp - Offset = Heat Mode Off
80 - 4 = 76
8.3.2. Cool Mode:
If the Target Temp is set at 80 degrees, Offset set at 5 degrees, and Differential set at 2
degrees, The System will engage the fans when building temperature reaches 87
degrees.
Example: Target Temp + Offset + Differential = Cool Mode On
80 + 5 + 2 = 87
If the Target Temp is set at 80 degrees, Offset set at 5 degrees, and Differential set at 2
degrees, The System will disengage the fans when building temperature reaches 85
degrees.
Example: Target Temp + Offset = Cool Mode Off
80 + 5 = 85
