- 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.

(COC/NH) Change over dry contact. Normally Heat: Used for hot / cold water or
air change over switching in 2 pipe systems.
Contact closed = Cold water or air present
Contact opened = Hot 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
Contact opened = Cold 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.
If water temperature is > 78 °F = Hot water present
If water temperature is < 75 °F = Cold water present

Only used for network reporting of the supply air temperature. Has no internal
function in the thermostat.
MenuScro
Menu scroll
Default value = On = Scroll active
Removes the scrolling display and only present the room temperature/humidity to the user.
With this option enabled, no status is given of mode, schedule and outdoor temperature.
On = Scroll active
Off = Scroll not active
AutoMode
Enables Auto menu for Mode
button
Default value = Off
Enables Auto function for the mode button
For sequences 2, 4 & 5 only
On = Auto active (Off-Cool-Heat-Auto)
Off = auto not active (Off-Cool-Heat)
C or F
Sets scale of the thermostat
Default value = °F
°F for Fahrenheit scale
°C for Celsius scale
On hotel models, this sets the default value when the thermostat powers up

System type installation
Number of pipes
Default is: 4.0 Pipes
Defines the type of system installed
2.0 Pipes, will limit the number of sequences of operation available from 0 to 3
Will enable heat/cool operation from the same output ( refer to wiring diagram )
4.0 Pipes, can access all the sequences of operation from 0 to 5
Will enable heat/cool operation from different output ( refer to wiring diagram )
