Feature

Description

Security

Security initiates a keypad lockout.  The control can only be accessed by a four digit pass code which 
can be configured in two different formats:
Pin Lock:  When the Pin Lock is selected, the control is completely locked.  The user will need to enter 
a four digit password to change any setting (the default is “1234”).
Guest mode:  The enabling of this mode allows a guest to change the temperature up to 5° in either 
direction from setpoint and access to the weather, but cannot change the mode or any customized 
settings. Note: The back door password is 9467.

Network Diagnostics

Screen gives the user the ability to view the wireless connectivity of the 950 Control. Save Diagnostic 
Logs is used to record wireless data for troubleshooting purposes

Setpoint Dead Band

This sets the temperature band between heating and cooling setpoints while in the auto mode.

Software Updates

The control is field software upgradable. The software can be upgraded by two methods:

USB Flash Drive upgrade

 - Insert a USB Flash Drive with new software loaded and use the software 

upgrade screen to complete the upgrade process.

Internet upgrade

 - Use the software upgrade screen to complete the upgrade process

System Report

The System Report Screen provides a real time in depth look at operating conditions.  While similar 
to the System Status screen, the system report adds additional information for service technicians.  

Test Mode

There are three Test Modes in the control:

System Test

 - Ability to test heating/cooling/blower/humidifier and aux contacts for up to 30 minutes.

Damper Test

 - Ability to test damper operation (see Zone Panel IG for more information).

Variable Speed Test

 - 

Technician Access 

Screens

The “Technician Access” icon has a 5 second hold delay to enter the technician service screens.   After 
this 5 second hold delay, the technician will see a “Caution!” screen noting that only a trained HVAC 
technician should proceed into this area.    

Ventilation

The 950 control has the ability to control a ventilation system through the AUX contacts of a Relay 
Panel (Model BAY24VRPAC52DB* or newer). This function is enabled in the Installer Setup > 
Advanced > Accessories > Ventilation Installed. Once enabled the minimum ventilation can be 
set for each hour. Ventilation can be overridden during extreme temperature conditions by setting 
a maximum and minimum outdoor temperature for ventilation operation (wired outdoor sensor 
must be connected and enabled). Additional options are available to accumulate overridden 
runtime. All options are available for selection in Installer Setup > Advanced > Accessories section.   

 

Note

: Currently there is no option to interlock the blower with a call for ventilation.

Warm Air Discharge

Enabling Warm Air Discharge will reduce the variable speed blower air flow by 20% when in compressor 
heating operation.  Warm air discharge only applies to compressor heating and is disabled when 
hydronic, fossil fuel or electrical heat (including supplement heat) modes are activated.

Whole House                

Dehumidifier

The 950 control has the ability to control a whole-house dehumidifier through the AUX contacts of 
a Relay Panel (Model BAY24VRPAC52DB* or newer). This function is enabled in the Installer Setup 
> Advanced > Accessories > Dehumidifier Installed. The dehumidifier can be setup for stand-alone 
operation or only when the system is actively cooling. The user can also select whether the blower will 
be energized with a call for dehumidifier operation. Dehumidifier operation is only allowed in Cooling 
Mode or in Auto Mode when the last call for operation was cooling.
