Issued June 30, 2014

Applications

The T600MSN-3 non-programmable and T600MSP- 3
programmable thermostats are specifically designed
for control of multi-stage commercial heating and
cooling equipment.

IMPORTANT: The T600MSx-3 Thermostat is
intended to provide an input to equipment under
normal operating conditions. Where failure or
malfunction of the thermostat could lead to personal
injury or property damage to the controlled
equipment or other property, additional precautions
must be designed into the control system.
Incorporate and maintain other devices, such as
supervisory or alarm systems or safety or limit
controls, intended to warn of or protect against
failure or malfunction of the thermostat.

IMPORTANT: Le T600MSx-3 Thermostat est
destiné à transmettre des données entrantes à un
équipement dans des conditions normales de
fonctionnement. Lorsqu'une défaillance ou un
dysfonctionnement du thermostat risque de
provoquer des blessures ou d'endommager
l'équipement contrôlé ou un autre équipement, la
conception du système de contrôle doit intégrer des
dispositifs de protection supplémentaires. Veiller
dans ce cas à intégrer de façon permanente
d'autres dispositifs, tels que des systèmes de
supervision ou d'alarme, ou des dispositifs de
sécurité ou de limitation, ayant une fonction
d'avertissement ou de protection en cas de
défaillance ou de dysfonctionnement du thermostat.
