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.
