Space Temperature Sensor
The OE210, OE211, OE212, OE213 Space Temperature Sensor is typi-
cally used for constant volume HVAC unit applications controlling one
zone. The Space Temperature Sensor is a 10K Type III thermistor sensor
and should be mounted approximately 5 feet above the fl oor in the space
that is to be controlled. The Space Temperature Sensor is available as a
sensor only, sensor with override button, sensor with slide adjust, and
sensor with slide adjust and override confi gurations.
When the Remote Supply Air Temperature Reset Signal option is needed,
the Slide Offset option on the Room Sensor cannot be used. Only one
of these options may be used on the RNE Controller.
See Figure 10 below for complete Space Temperature Sensor wiring
details.

Remote SAT Reset Signal
Remote SAT Reset Signal
A Remote Supply Air Temperature Reset Signal can be connected to AI7
for applications requiring remote reset of the Supply Air Temperature
Setpoint.
When the Slide Offset option on the Room Sensor is used, the Remote
Supply Air Temperature Reset Signal cannot be used. Only one of these
options may be used on the RNE Controller.
The RNE Controller can accept either a 0-5 VDC signal or a 0-10 VDC
signal on this input.
See Figure 11 below for complete Remote SAT Reset Signal wiring
details.
