OPERATING MANUAL FOR HEATSAN   

98-0177A 

  Page 5 

Conductivity 

The Conductivity is shown on the top line after the unit operating status. When 
the unit is in STANDBY, because of a shut down condition, the reading is 
replaced with ‘----’.  If the reading is over range, the reading is shown as ‘^^^^’ 
when in the OPERATE mode. 

Operating Hours 

The current operating hours are shown on the bottom line. 

Temperature 

The current water temperature is shown on the bottom line to the right of 
operating hours. When the unit is in STANDBY due to a shut down condition, 
the reading is replaced with ‘---‘. 

Warning Messages 

Warning messages are also shown on the second line. If any warnings are 
active, the active warnings will alternate with the normal displays for the 
bottom line. The following lists the warning messages. 

HI COND - The Conductivity reading has exceeded the programmed limit. 

Tank Full Operation 

The unit can be operated with 1 or 2 level switches. With 1 level switch, the 
switch is connected to the tank full high input. When this switch has been 
active for 5 seconds, the unit will shut down on tank full. TANK FULL will show 
on the display. When the tank full condition clears, the display will show TANK 
FULL 99. The number is the tank full restart time and the unit will restart when 
this delay times out.  

For 2 level switch operation, the upper switch is connected to the tank full high 
input and the lower switch is connected to the tank full low input. When both 
switches are “open”, the MRO unit will start. The MRO unit will continue to run 
when the water level rises, and while the lower switch becomes active 
(closed). When the upper switch becomes active (closes), after the 5 second 
delay, the MRO unit will shut down. TANK FULL will show on the display. 
When the tank level drops and the upper level switch clears, the display will 
show TANK FULL 99 and the MRO unit will remain off. The number is the 
tank full restart time and the number will blink until the lower level switch 
clears (opens).  When the lower level switch clears (opens), the number will 
remain steady and the MRO will restart when the delay times out.
