IMPORTANT
To avoid electrical interference, which can cause
erratic performances, 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.

providing temperature averaging network for
T7300/Q7300 Thermostat/Subbase.

temperature averaging network for
T7300/Q7300 Thermostat/Subbase.

temperature averaging network for
T7300/Q7300 Thermostat/Subbase.
Fig. 7. Nine T7047C Sensors providing temperature
averaging network for T7300/Q7300 Thermostat/Subbase.
NOTE:
When thermostat is configured for temperature
averaging network (remote and internal sensing), the
internal sensor has 50% authority of the averaged
temperature.
Mounting Subbase or Wallplate
The subbase or wallplate mounts horizontally on the wall or a
2 in. x 4 in. wiring box. Position the subbase or wallplate
horizontally on the wall or on a 2 in. x 4 in. wiring box.
1. Position and level the subbase or wallplate (for
appearance only). The thermostat functions properly
even when not level.
2. Use a pencil to mark the mounting holes. See Fig. 8.
