Remote Room Sensors - Observer TSTAT0201CW Installation Manual

Remote Room Sensors

(for non-zoned system)
A Remote Room Sensor (Part No. SYSTXIIRRS01) can be
used with the Observer Control to take the place of the con-
®
trol's internal temperature sensor (This sensor is NOT the
same as the Zone Temperature Sensor, even though the
part numbers are similar). This allows the Observer Control
to be mounted in areas with less than optimal airflow (such
as near an exterior door, window or in a closet). The remote
sensor can be wired to the terminal block connectors labeled
S1 and S2 at the control's back-plate. The Observer Control
will automatically detect the Remote Room Sensor and ig-
nore its internal temperature sensor. Typically, one remote
sensor is used but, multiple sensors may be used and aver-
aged in some applications. Averaging requires a special
series-parallel wiring method with a specific number of
sensors. See Fig. 1. It is also important to note the humidity
sensor cannot be remotely located, so do not locate the Ob-
server Control in an area where humidity sensing may not be
accurate.
