The alarm condition can only be cleared by pressing the RESET button. The is ideal for domestic hot water systems. When the domestic water temperature rises above the selected set point, the will enter the Alarm Mode. The will control a solenoid valve. In the Alarm Mode, the solenoid valve will close the flow of hot water to the domestic system. To open the solenoid valve and let the hot water back into the system, two things must happen: the domestic water temperature must fall below the critical point, and the RESET button must be pressed. ETV Control Module ETV Control Module Tempered Cold NC Solenoid Hot HOT WATER SOURCE Typical uses of the include: Domestic Hot Water (DHW) alarm Freeze condition alarms Refrigeration system alarms Hydronic heating systems high temperature alarms and control for solenoid valve to disable the heating system Space temperature alarm systems Status Mode The operation has two status modes: Normal: In this mode, the System Sensor (temperature or pressure) is not in a critical zone. Critical zone is when the sensor reading is above the Set Point in Heating or below the Set Point in cooling. The solenoid valve will be open and its LED will be on. Alarm LED and Alarm relays will be de-energized. Alarm: The will automatically enter this mode whenever the System Sensor reading enters the critical zone. The will then close the solenoid valve (regardless of the Solenoid Valve type selected from the Startup menu). The Valve Open LED will be off and the Alarm LED will be blinking. All alarm outputs will be energized. Warning To Exit the Alarm Mode, the System Sensor must be out of the critical zone and the RESET button must be pressed.
