Temperature Control Diagnostic Codes
Temperature control diagnostic codes appear on tem-
perature display.
These alarms turn off heat. E99 clears automatically
when communication is regained. Codes E03 through
E06 can be cleared by pressing
. For other codes,
turn main power OFF
then ON
to
clear.
NOTE: For hose zone only, if FTS is disconnected at
startup, display will show hose current 0A.
E01: High fluid temperature
Causes of E01 Errors
•
Thermocouple A or B (310) senses a fluid tempera-
ture above 230°F (110°C).
•
Fluid temperature sensor (FTS) senses a fluid tem-
perature above 230°F (110°C).
•
Overtemperature switch A or B (408) senses a fluid
temperature above 230°F (110°C) and opens. At
190°F (87°C) the switch closes again.
•
Thermocouple A or B (410) fails, is damaged, is not
touching the heater element (407), or has a poor
connection to the temperature control board.
•
Overtemperature switch A or B (408) fails in the
open position.
•
The temperature control board fails to turn off any
heat zone.
•
Zone power wires or thermocouples are switched
from one zone to another.
•
Failed heater element where thermocouple is
installed.
•
Loose wire
Checks
Check which zone is displaying the E01 error.
1. Check that connector B is firmly plugged into tem-
perature control module (see F
2. Clean and re-plug connections.
3. Check connections between the temperature con-
trol module and overtemperature switches A and B
(308), and between temperature control module and
thermocouples A and B (410) or FTS (21) [depend-
ing on which zone is displaying E01]. See T
page 36. Ensure that all wires are securely con-
nected to connector B.

Troubleshooting this equipment requires access to
parts that may cause electric shock or other serious
injury if work is not performed properly. Have a quali-
