Honeywell T7412E PRODUCT DATA

GENERAL

The temperature sensor is used for room temperature measurement in Excel 500 heating, ventilating and air control systems. It is suited for wall mounting and incorporates an occupancy extend button. As a passive product, this sensor is not subject to the requirements of CE.

INSTALLATION

Observe the following 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 temperature measurement due to draught from the conduit.

NOTE: Use shielded wiring in areas with high EMI. Keep

15 cm (5.9’’) minimum distance between sensor lines and 230 Vac power lines.
