Temperature Control Diagnostic Codes
8 312063Z
Temperature Control Diagnostic Codes
Temperature control diagnostic codes appear on
temperature 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
temperature above 230°F (110°C).
• Fluid temperature sensor (FTS) senses a fluid
temperature above 230°F (110°C).
• Overtemperature switch A or B (308) senses a fluid
temperature above 230°F (110°C) and opens. At
190°F (87°C) the switch closes again.
• Thermocouple A or B (310) fails, is damaged, is not
touching the heater element (307), or has a poor
connection to the temperature control board.
• Overtemperature switch A or B (308) 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
• On 8 kW heater models only: Jumper wire on J1
connector, between module (3) and display (4), is
loose or incorrectly wired.
Checks
Check which zone is displaying the E01 error.
1. Check that connector B is firmly plugged into
temperature control module (see F
IG. 8, page 34).
2. Clean and re-plug connections.
3. Check connections between the temperature
control module and overtemperature switches A and
B (308), and between temperature control module
and thermocouples A and B (310) or FTS (21)
[depending on which zone is displaying E01]. See
T
ABLE 6, page 34. Ensure that all wires are securely
connected to connector B.
4. Remove connector B from temperature control
module, and check continuity of overtemperature
switches A and B, thermocouples A and B, or FTS
by measuring resistance across the pins on the plug
end; see T
ABLE 1.
CAUTION
To prevent damage to soft key buttons, do not press
the buttons with sharp objects such as pens, plastic
cards, or fingernails.

Troubleshooting this equipment requires access to
parts that may cause electric shock or other serious
injury if work is not performed properly. Have a
qualified electrician perform all electrical
troubleshooting. Be sure to shut off all power to the
equipment before repairing.
