Johnson Controls TCN-890x Installation Instructions Manual

TCN-890x Electronic Room Thermostats
Installation
Install the TCN-890x where the occupant can read and
adjust the setpoint dial selector easily. Situate the
module where the temperature is representative of the
general room conditions. Avoid installing the
TCN-890x near cold or warm air drafts, radiant heat, or
direct sunlight.
IMPORTANT: The TCN-8900 Series electronic
room thermostats are intended to control equipment
under normal operating conditions. Where failure or
malfunction of the TCN-890x thermostat could lead
to an abnormal operating condition that could cause
personal injury or damage to the equipment or other
property, other devices (limit or safety controls) or
systems (alarm or supervisory) intended to warn of,
or protect against, failure or malfunction of the
TCN-890x thermostat must be incorporated into and
maintained as part of the control system.
IMPORTANT: Do not mount the module on an
exterior wall. Make all wiring connections in
accordance with the National Electrical Code and all
local regulations.
