Problem
Solution
High Temperature Alarm
A. The process temperature has exceeded the
“High Temperature Alarm Set Point”
. If the
“High Temperature Alarm Set Point”
is set
correctly, then make an adjustment in the
Control Settings
screen to the
“Power
Adjust”
parameter. Reset this parameter to –5
counts. See if this solves the issue. If not,
continue reducing the count by five until the
issue is resolved.
Low Flow Alarm
A. The flow rate has dropped below the
“Low
Flow Alarm Set Point”
or the minimum
required flow rate of 0.5gpm. Increasing the
flow rate or decreasing
“Low Flow Alarm Set
Point”
may resolve this problem. Please note
that a minimum flow rate of 0.5gpm is required
for the heaters to turn ON.
High Pressure Alarm
A. Danger – The system exceeds
“High
Pressure Alarm Set Point”
. It is
recommended that the system pressure be less
than 65 psi. Reduce the pressure in the
system by shutting off the water supply and
opening the output valve.
Discharge Temperature is not stable
A. Check all parameters in the
Control Settings
screen and compare them to the Factory
Settings.
B. Calibrating the Heater Amperage may be
needed if the incoming voltage is fa
The “manual” Purge feature is not
functioning
(Optional on Aquarius
D.I. Water
Heating Systems only)
A. Verify that an adequate supply of air is present.
B. Verify that the solenoid valves are operational.
C. Verify that the air operated valves (AOV) are
operational.
