Since there is not currently a forum for the CM1800, I'll ask this question here.
Does anyone know if there is a way to add hysteresis to the temperature control of the CM1800? It turns the compressor off or on with only a one degree change, which may result in insufficient pressure equalization before the compressor restarts. Does anyone know if there is a way to add hysteresis - set it so that it takes a two-degree drop before the compressor will turn back on? I was going to install a "delay after break" time delay in the SSR control, but I've had difficulty finding an appropriate device that works in the DC control circuit. Does anyone have other suggestions?
