I have 2-90 kw and 1-100 kw make up units with six stage scr regulated discharge temperature control but would like to have the capacity to have the setpoint set back (get warmer) as outside air temps drop toward overnight lows and then RESET to the original setpoint after O/A temps warm. I have similar capacity on chillers with Honeywell step controllers. Any ideas or recomendations???
