OVERVIEW - READ ME BEFORE PROCEEDING!
1. The LEGIOMIX valve is factory pre-configured for basic mixed temperature control. All
thermal disinfection functionality and the SHOCK button are disabled (but can be easily enabled
in the Menu if needed).
2. Once mounted, wired, and powered up with
24 volts AC (field-provide a 115/24 VAC
transformer)
, you will be prompted to set the Date, Time, and Region (USA) in the LCD
display. The procedure is described below.
3. After setting the Date, Time, and Region, the control will run an “anti-clog” cycle (2 full
strokes of the valve). This takes a few minutes. It then automatically goes to “Adjustment
Running” mode for normal operation.
4. In normal operation, the green LCD screen shows Day, Date, mixed temperature “Tm” and
return temperature “Tr” in degrees °F, and control mode. This display will also show alarms, log
data, etc. if they occur.
5. The two gray/red LED segments labeled “Mixed °C” and “Return °C” will be off when °F is
selected. If the temperature units are changed to °C, in the configuration menu, these segments
will show °C. These LED segments will also indicate a problem with the resistance at the sensor
terminals, even if the LED displays are off.
6. Relay contact outputs 1, 2 and 4 are for thermal disinfection applications only; ignore if doing
mixing control. Relay 3 is a general alarm which can be connected, if desired; see manual for
details.
