Tracer® ZN.010
and ZN.510
Analog Inputs
Both Tracer® ZN.010 and ZN.510 accept a maximum of five analog inputs. Reference Table 7.
Table 7. Analog Inputs Available
Analog Input | Description | Application |
Zone | Space temperature | Space temperature detection |
Set | Local setpoint | Thumbwheel setpoint |
Fan | Fan mode input | Zone sensor fan switch |
Analog input 1 (AI1) | Entering water temperature | Entering water temperature detection |
Analog input 2 (AI2) | Discharge air temperature | Discharge air temperature detection |
Notes:
1.The zone sensor, entering water temperature sensor, and the discharge air temperature sensor are 10KW thermistors. Figure 26 on page 38 provides the
2. Zone Sensor:
Wall mounted sensors include a thermistor soldered to the sensor’s circuit board Unit mounted sensors include a return air sensor in the unit’s return air stream.
3. Changeover units include an entering water temperature sensor.
Zone Sensors
Fan Mode Switch
The zone sensors available with the Tracer® ZN.010 and ZN.510 provide up to three different inputs
1.Space temperature measurement (10K thermistor)
2.Local setpoint
3.Fan mode switch
Wall mounted zone sensors include a thermistor as a component of the internal printed circuit board. Unit mounted zone sensors use a sensor placed in the unit’s return air stream.
Each zone sensor is equipped with a thumbwheel for setpoint adjustment.
The zone sensor may be equipped with a fan mode switch. The fan mode switch offers selections of off, low, medium, high, or auto. Reference Table 8 on page 45 for fan mode operation.
