14.5 Addressing Sensors

When multiple FHP ZS Combo Sensors (up to 5 max) are connected to the FHP560 controller, each sensor on the Rnet must have a unique address
associated with it, and the addresses have to be sequential. If the sensors are not addressed sequentially the FHP560 reads any gaps as faulty
sensors and a sensor wiring alarm is generated.
The DIP switches located at the back of the sensor (next to the Rnet connector block) may be used to set an address from 1 to 5 (the factory
default address for all FHP branded ZS sensors is "1").
There are four (4) DIP switches (numbered 1 through 4) used to address the ZS sensors. Each DIP switch has a value assigned to it for addressing
the sensors as shown in the Table 41:
DIP Switches
DIP Switch Number DIP Switch Value
1 1
2 2
3 4
4 8
Table 41
Turn on as many DIP switches as needed so that their total value equals the required address. In the below example (see Fig. 11), DIP switches #1
and #4 are ON (to the right position). Their values (1 + 8) total 9, so the sensor's address is 9.
While the DIP switches may be used to address the
sensor for any value from 0 to 14, the FHP560 ONLY
recognizes values from 1 to 5, and any other address will
result in the sensor(s) not functioning properly.
14.6 Confi guring Multiple Sensors
Multiple ZS Combo Sensors on an Rnet must be confi gured in the software (using a BACview interface) in order for the FHP560 to function as
required.
Any combination of sensing capabilities may be used (Temperature, Relative Humidity, CO₂), and the effective value used to control the unit may
be confi gured as the minimum, maximum, or average of all the individual values.

14.7 Formatting Sensors

Formatting a sensor clears its fl ash memory. To format a sensor perform one of the two below:
1. Download the controller that the sensor is connected to with new software.
2. Perform the following steps:
2.1. Remove the wiring connector from the sensor
2.2. Note the current position of the DIP switches
2.3. Set all DIP switches to the ON position
2.4. Reattach the wiring connector to format
2.5. After approximately 3 seconds, remove the wiring connector
2.6. Set the DIP switches back to their original position
2.7. Reattach the wiring connector
