ViewStat Communicating Thermostat - Programming Protocol Reference Guide
Description
Set the default (CP=1) or custom (CP=2) control system configuration pattern.
The ViewStat can retain two independent sets of communication configuration
settings. Each set contains the state of all Change-Of-State (COS) settings
and the Command Response (CR) setting. Default values for CP #1 and CP #2
are shown below.
IMPORTANT: Once a configuration pattern has been selected, any changes
you make to the communications control commands are assigned to the active
configuration pattern.
By default, CP #1 is active upon startup. The benefit of this command is to
facilitate having a standard configuration for normal operation and a second
configuration for special functions. CP #2 is convenient for those who wish to
integrate the text messaging display into their automation system. You may
alternate between these two configurations by simply sending the Configuration
Pattern command.
Syntax:
SN[address] CP=<pattern>
Parameters:
• <address> = 0 (global), or 1 through 64 (thermostat-specific address)
• <pattern> = 1 or 2
Reply Format:
SN[address number] CP=1 or 2 No response sent when set to CP=1
(i.e. no response to SN1 CP=1)
Default Settings for
Configuration Pattern 1:
CR = Normal
C1 = Off
C2 = Off
C3 = Off
C4 = Off
C5 = Off
C6 = Off
C7 = Off
C8 = Off
C9 = Off
C10 = Off
C11 = Off
C12 = Off
Syntax:
SN[address] HOLD=ON or OFF
Parameters:
• <address> = 0 (all thermostats), or 1 through 64 (thermostat-specific
address)
The ViewStat incorporates an ENTER button. This button has three functions:
• Thermostat Set-up - During Thermostat Set-Up the user interacts with the text
messaging display to select various operational parameters and this button is
used to enter those selections.
• User Reset Message Resetting - When the thermostat receives a User Reset
Message command this button is used clear the message from the text
messaging display.
• Network Override - During all other times, this button is used to override
network control of the thermostat: temperature changes, mode changes and
fan state changes are controlled only by the buttons on the thermostat.
This command can be used to change the Network Override status or HOLD
status regardless of what the text messaging display is doing. When activated
(HOLD = ON), "NETWORK OVERRIDE" shows on the ViewStat display. The
NETLK command enables or disables this feature.
