INSTALLATION INSTRUCTIONS
WARNING
Electrical Shock Hazard - Turn o power at the main
power source before installing the ETC control.
DO NOT restore electrical power to the unit unl the
ETC control is properly installed and cover assembled.
Fire Hazard - DO NOT locate the ETC control in an
explosive atmosphere as a re could result due to
possible spark generaon in the control.
All ETC Controls are designed as temperature controls
and are not used as temperature limit controls.
Where failure or malfuncon of the ETC control could
cause personal injury or property damage, other
devices (limit or safety controls) or systems (alarm
or supervisory) intended to warn or protect against
failure or malfuncon of the ETC control must
be installed.

INSTRUCTIONS CONCERNANT L’INSTALLATION
AVERTISSEMENT
Risque de choc électrique - Couper le courant à la
source d’alimentaon principale avant d’installer le
contrôleur ETC. NE PAS rétablir l’alimentaon élec-
trique de l’appareil avant que le contrôleur ETC ne
soit correctement installé et que le couvercle ne soit
assemblé.
Risque d’incendie - Ne pas placer le contrôleur ETC
dans une atmosphère explosive car un incendie
pourrait être déclenché par d’éventuelles éncelles
survenant dans le contrôleur.
Toutes les commandes de l’ETC sont conçues pour
contrôler la température et ne sont pas ulisées com-
me témoins des limites de température.
Si une défaillance du contrôleur ETC peut causer
des blessures ou des dommages matériels, d’autres
disposifs (contrôles des limites ou de la sécurité) ou
des systèmes (d’alarme ou de surveillance) desnés
à prévenir ou à protéger contre une défaillance ou un
dysfonconnement du contrôleur ETC, doivent être
installés.
TROUBLESHOOTING ERROR MESSAGES
Display Messages
E1 Appears when either the up Ç or down È key is pressed when not
in the programming mode.
To correct: If the E1 message appears even when no keys are being
pressed, replace the control.
E2 Appears if the control sengs are not properly stored in memory.
To correct: Check all sengs and correct if necessary.
EP Appears when the probe is open, shorted or sensing a temperature
that is out of range.
To correct: Check to see if the sensed temperature is out of range.
If not, check for probe damage by comparing it to a known
ambient temperature between -30°F and 220°F. Replace the
probe if necessary.
EE Appears if the EEPROM data has been corrupted.
To correct: This condion cannot be eld repaired.
Replace the control.
CL Appears if calibraon mode has been entered.
To correct: Remove power to the control for at least ve seconds.
Reapply power. If the CL message sll appears, replace the control.
