Input from its on-board temperature sensor or remote temperature, humidity and water sensing probes, allows this digital control system to provide dual-zone coverage for precise monitoring of critical environments. The EA400 accepts four sensor inputs and has alarm outputs that include four configurable SPDT relays. Digital control provides flexibility for simultaneously monitoring and the user-friendly configuration of eight event alarms with memory storage and time and date recording. Among the programmable features is a delay time entry mode that ignores programmed limits in a situation such as a defrost cycle for the time specified in the time delay.
