INSTALLING THE THERMOSTAT
DISASSEMBLY
Insert a small coin (dime) in the release slot located
on the bottom of the thermostat. Gently twist the coin
to release the thermostat from the subbase. Avoid
twisting the case as this may stress the LCD or bend
the terminal connector pins. (Figure 1)
THERMOSTAT LOCATION
The thermostat should be installed in a location that
represents the ambient space temperature. Do not
install the thermostat in an area where drafts are
present, near the floor, behind doors or on an external
wall. Avoid placing the thermostat in areas where the
air movement is limited, affected by direct sunlight or
other areas not typical of the temperature in the
space.
MOUNTING THE SUBBASE
When mounting the thermostat, be aware that drafts
may travel down wall cavities and enter the back of
the thermostat through the control wire hole in the
wall. It is important to seal the hole to prevent any
drafts that might affect the internal temperature FIGURE 1
As with any HVAC project, careful installation is the key to a successful outcome. Time taken during
the installation process will be rewarded with fewer call-backs.
