TH-2005 EXCEL PROGRAMMABLE THERMOSTAT
USER'S GUIDE (E-Series)
Choosing location for INSTALLATION
For obtaining thermostat's best performance upon using,
recommend user to follow up with precaution listed below.
(1). Place thermostat on wall inside the room approximate
1.5 meter above floor.
(2). Avoid position where temperature sensing easily interfered
by ambience, such as, directly exposed to Sun-Light, too
near to any Heat-Generate devices/refrigerator, right next to
entrance/exit/window, etc.
(3). Prevent thermostat from installed at position that furniture
may interfere air-flow, stagnant air-flow location is not
suitable for installing thermostat.
(4). Keep thermostat away from high humid ambience, high
humidity is hazardous to thermostat's operational duration,
(5). It's crucial, before installing thermostat, make sure house
renovation is finished, no tacky painting/plaster is right
on thermostat's installing position.
(6). To level thermostat prior to installation is not necessary
