Q7300L SERIES 2000 COMMERCIAL THERMOSTAT SUBBASE
Location
Subbase without Remote-Mounted
Temperature Sensor
Install the thermostat about 5 ft (1.5m) above the floor in
an area with good air circulation at average temperature.
See Fig. 1.
Do not install the thermostat where it can be affected by:
— drafts, or dead spots behind doors and in corners.
— hot or cold air from ducts.
— radiant heat from sun or appliances.
— concealed pipes and chimneys.
— unheated (uncooled) areas such as an outside wall
behind the thermostat.
Subbase with Remote-Mounted
Temperature Sensor(s)
If only the remote-mounted temperature sensor(s) is used
to sense and control room temperature, then install the
thermostat in an area that is accessible for setting and
adjusting the temperature and settings.
If both the subbase and remote-mounted temperature
sensor(s) are used to sense and control room tempera-
ture, then install the subbase about 5 ft above the floor in
an area with good air circulation.
Install the remote-mounted sensor(s) about 5 ft (1.5m)
above the floor in an area with good air circulation at
average temperature. See Fig. 1.
Do not mount the sensor(s) where it can be affected by:
— drafts, or dead spots behind doors and in corners.
— hot or cold air from ducts.
— radiant heat from sun or appliances.
— concealed pipes and chimneys.
— unheated (uncooled) areas such as an outside wall
behind the thermostat.
If more than one remote sensor are required, they must be
arranged in a temperature averaging network consisting of
two, three, four, five or nine sensors. See Fig. 2 through 6.
IMPORTANT
To avoid electrical interference, which can cause
erratic performance, keep wiring runs as short as
possible and do not run thermostat wires
adjacent to the line voltage electrical distribution
systems. Use shielded cable (Belden type 8762
or equivalent for 2-wire and Belden type 8772 or
equivalent for 3-wire). The cable shield must be
grounded only at the controlled equipment case.
