- 1. (None): No function will be associated with the input
- 4. (Filter): a backlit flashing Filter alarm will be displayed on the thermostat LCD screen when the input is energized. It can be tied to a differential pressure switch that monitor filters
- 5. (Service): a backlit flashing Service alarm will be displayed on the thermostat LCD screen when the input is energized. It can be tied in to the AC unit control card, which provides an alarm in case of malfunction.
- 1. (None): No function will be associated with the input
- 2. (COC/NH) Change over dry contact. Normally Heat: Used for hot / cold water change over switching in 2 pipe systems.
- Contact closed = Cold water present
- Only used and valid if system is setup as 2 pipes. Parameter ( Pipe No ) set as 2 pipes.
- 3. (COC/NC) Change over dry contact. Normally Cool: Used for hot / cold water or air change over switching in 2 pipe systems.
- Contact closed = Hot water present
- Only used and valid if system is setup as 2 pipes. Parameter ( Pipe No ) set as 2 pipes.
- 4. (COS) Change over analog sensor: Used for hot / cold water or air change over switching in 2 pipe systems.
- Only used and valid if system is setup as 2 pipes. Parameter ( Pipe No ) set as 2 pipes.
- 5. (SS) Supply air sensor monitoring: Used for supply air temperature monitoring.
- Only used for network reporting of the supply air temperature. Has no internal function in the thermostat.
- Range is: 0 to 500
- This parameter (Personal Area Network Identification) is used to link specific thermostats to a single specific Viconics wireless gateway ( VWG ) For every thermostat reporting to a gateway ( maximum of 30 thermostats per gateway ), be sure you set the SAME PAN ID value both at the gateway and the thermostat(s).
- Range is: 10 to 26
- Viconics recommends using only the 2 last channels ( 25-2575MHz and 26-2580MHz )
- Range is: 0 to 254
- This parameter / function is not currently supported by the wireless thermostats.
- BI1
- Default value = None
- (None): No function will be associated with the input
- (Filter): a backlit flashing Filter alarm will be displayed on the thermostat LCD screen when the input is energized. It can be tied to a differential pressure switch that monitor filters
- (Service): a backlit flashing Service alarm will be displayed on the thermostat LCD screen when the input is energized. It can be tied in to the AC unit control card, which provides an alarm in case of malfunction.

- Contact closed = Cold water or air present
- Only used and valid if system is setup as 2 pipes. Parameter ( Pipe No ) set as 2 pipes.
- (COC/NC) Change over dry contact. Normally Cool: Used for hot / cold water or air change over switching in 2 pipe systems.
- Contact closed = Hot water present
- Only used and valid if system is setup as 2 pipes. Parameter (Pipe No ) set as 2 pipes.
- (COS) Change over analog sensor: Used for hot / cold water or air change over switching in 2 pipe systems.
- Only used and valid if system is setup as 2 pipes. Parameter (Pipe No ) set as 2 pipes.
- (SS) Supply air sensor monitoring: Used for supply air temperature monitoring.
- 2.0 Pipes, will limit the number of sequences of operation available from 0 to 3
