Q7300H SERIES 2000 COMMERCIAL THERMOSTAT SUBBASES
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.
— Uncontrolled areas such as an outside wall behind the
thermostat.
Subbase With Remote-Mounted
Temperature Sensors
If only remote-mounted temperature sensors are
used to sense and control room temperature, install
the thermostat in an area 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
temperature, 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.
— Uncontrolled areas such as an outside wall behind the
thermostat.
If more than one remote sensor is required, arrange them
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.
