I’m using an A2192 Chamber Enhancer Board. Are there any mandatory settings?
It is imperative that the Inc & Dec Cycle time of the 620A control channel and the A2192 board Cycle time dip switch settings match. If they do not then the information interpreted by the A2192 will be incorrect and result in incorrect output functions. See the A2192 manual for Heat & Cool Dip switch definitions and settings. Note: The Model 620A is connected to the A2192 board by 4 wires. The wires from the 620A are not pin for pin compatible with the input pins of the A192. 620A ,TB1 Pin to A2191, TB1 Pin 1 1 +9vdc 2 4 Gnd 3 2 Inc 4 3 Dec Back to the top.
