Operation terminal for TCX2 controller
with internal temperature sensor
Mounting location
•Install the operation terminal on an easy accessible interior wall, approx. 1.5 m above the floor in an area of average
temperature.
•Avoid direct sunlight or other heat sources, e.g. the area above radiators and heat emitting equipment.
•Avoid locations behind doors, outside walls and below or above air discharge grills and diffusers.
•Location of mounting is less critical if external temperature sensors are used.
Installation
See installation sheet no. 70-000113C (www.vectorcontrols.com).
