Getting Started
Digital Signature
IMPORTANT
All the Honeywell WEBs software tools are now signed. Users can verify the signature using any OpenSSL tool.
Below are the steps to verify signature using OpenSSL community distribution.
Prerequisites:
• Download the Honeywell public key BuildingsCommonSupervisor.crt from location- same location as the
software release location
• Download the batch file “VerifyWEBsToolsSignature.bat” from location- same location as the software
elease location. This file has the commands to verify the module signature using the public key specified i
r
ep 1
St
• Download OPENSSL from this link- https://www.openssl.org/source/openssl-1.0.2o.tar.gz
• Extract the file using any ZIP utility to get the folder “openssl-1.0.2o”
• In the extracted folder find the file “openssl.cnf”
• Set Windows environment variable OPENSSL_CONF=<PATH TO openssl.cnf>, for example
OPENSSL_CONF=C:\openssl-1.0.2o\apps\openssl.cnf
Steps to verify the signature:
1. Place the files BuildingsCommonSupervisor.crt, VerifyWEBsToolsSignature.bat, WEBs tools modules and
signature file in the same location. For example: Following files are in one place
a. BuildingsCommonSupervisor.crt
b. VerifyWEBsToolsSignature.bat
c. honeywellSpyderTool.jar
d. honeywellSpyderTool.jar.sig
2. Open the command prompt and navigate to the location of the above files.
3. Execute the batch file VerifyWEBsToolsSignature.bat against a module for verifying its signature, for example
- C:\Spyder_RELEASE\ > VerifyWEBsToolsSignature.bat honeywellSpyderTool.jar

Occupancy Configuration
Schedule Model: A user can set the device’s schedule
model as;
1. Setpoint Mode or
2. Occupancy Mode
Setpoint Mode: In setpoint mode, the controller logically
emulates residential thermostats. The space temperature
is controlled to "SP Mode Cooling SP" and "SP Mode
Heating SP". Each schedule period consists of a start time,
a heating setpoint, and a cooling setpoint.
Occupancy Mode: By default, ‘Schedule Model’ is in
‘Occupancy Mode’. The system will be switched to
‘Occupied Mode’ when the occupancy sensor detects
occupancy. Occupied Mode allows a user to configure
‘Comm Fails Occupied’, ‘System Block’ & ‘Internal
Schedule’ settings.
If a user selects ‘Setpoint Mode’ from the available
‘Schedule Model’, the fields for ‘Comm Fails Occupied’
and ‘System Block’ settings become disabled.

Bypass and Standby
System Block: The System Block is hidden when the
schedule model is in ‘Setpoint Mode’. When the schedule
model is in ‘Occupancy Mode’, it allows a user to switch
between the available options. Selecting “Show
Unoccupied/Off” places the controller in unoccupied state.
Internal schedule: It can be configured in both Occupancy
Mode & Setpoint Mode. By default, ‘Internal Schedule’ is
‘Disable’.
If the internal schedule is ‘Disable’, a user can adjust the
setpoint (within setpoint limits).
