H7012A,B Room Humidity / Temperature Sensor
Mounting and Installation Advice:
• Mount these units at the inside wall of the room to be
heated or air conditioned, away from doors, windows
and heat sources.
• Do not mount in niches, book shelves, behind cabinets
or curtains or where it could be exposed to solar
radiation.
• Seal the conduit opening to avoid false measurement
due to draught from the conduit.
• Provide sufficient air circulation.

Use shielded wiring in areas with high EMI.
Keep 15cm (5.9'') minimum distance between
sensor lines and 230Vac power lines.
Use two transformers: one for sensors and
actuators and one for the controller (see Fig. 3).
