Sequences of Operation Addison’s Sequence of Operation is generated dynamically based on equipment code string
Standard set of control methods are written (enabled) to the control program at the end of the production line
Custom ‘special’ Sequences can be generated by Addison Controls Engineering, at cost<br>

Goal: T-Stat compatible Units will be able to be ordered to be compatible with Thermostats
-2 Heat, 2 Cool, Dehum, Fan, Dehum
-W1, W2, Y1, Y2, D T-stat will need to be ordered up front and may be difficult to switch to/from in the field. T-stat will require isolating relays to be added to our unit T-stat control would basically reset setpoints for Supply Air based on call.<br>
