Lux Products PSP722E Install Batteries, Access and Navigate Installer Setup Menu, System Type

3.6. INSTALL BATTERIES

Install batteries at this time. For instructions, see BAT-

TERY INSTALLATION.

3.7. INSTALLER SETUP

Configuration items are selected from the Installer Set up Menu. They are stored in non-volatile RAM, and will be preserved even in the event that the unit’s batteries are run down, or removed, or the hardware reset on the rear of the unit’s circuit board of the thermostat is pressed.

NOTE: Pressing the S/W RESET button on the rear of the unit’s circuit board will write default values of all temperature programs and setup menus into the unit nonvolatile memory. Take care not to inadvertently press this button when the ther- mostat has been removed from the wall plate!

3.7.1 ACCESS AND NAVIGATE INSTALLER SETUP MENU

Note: Insure that all relays are off before making changes in the installer menu. There are two methods, which may be used to do this. Place the unit in the OFF mode and wait for 5 minutes or Press the H/W RESET button on the rear of the unit’s circuit board. Take care not to inadvertently press the S/W RESET button.

●To enter the Installer Setup Menu press and hold the Setup Button for 10 seconds.

●Use the NEXT button to scroll through its options. As you proceed the menu item number will be displayed in the left portion of the screen.

●Selections can be changed by pressing the UP/DOWN button.

●Moving from one menu item to the next and accept- ance of changes is done by pressing the NEXT button.

●All changes become effective when the unit exits the Installer Setup mode.

●The Installer Setup mode will be exited when the Setup button is pressed again, or, if no other keys are pressed for 20 seconds.

All settings, their choices and default values are given in

INSTALLER SETUP MENU WITH FURNACE SYSTEM TYPE SELECTED: and INSTALLER SETUP MENU WITH HEAT PUMP SYSTEM TYPE SELECTED AND FUTURE OUTDOOR SENSOR ENABLED.

3.7.1.1 SYSTEM TYPE

This option determines whether the thermostat is to con- trol a furnace and air conditioning system or heat pump system.

●In furnace mode the unit will make the proper W ter- minals live for Heating, and the proper Y terminals live for cooling.

●In Heat Pump mode the unit makes the proper Y ter- minals live for the first and second stages of a heat pump unit during heating or cooling. In this mode an additional stage of Aux Heat may also be activated through the W1 terminal.

3.7.1.2 HEAT STAGES

Set this to the number of non-compressor driven heat stages to use for temperature control by this system.

3.7.1.3COMPRESSOR STAGES (COOL/HEAT PUMP STAGES)

Set the number of compressor driven system stages to use for temperature control. These stages include all cooling or heat pump stages to be used for temperature control by this system.

3.7.1.4MODES

The modes setting selects what system modes will be available to the user. The selections available are system mode dependant:

●Heat-Off

●Cool-Off

●Heat-Off-Cool

●Heat-Off-Cool-Auto (Furnace Mode) or

●Heat-Off-Cool-Em Heat-Auto (Heat Pump Mode)

3.7.1.5 MINIMUM RUN TIME

Minimum Run Time provides compressor protection and prevents short cycling. Compressor stages are held off for a minimum of this time. During program run this is also the minimum on time.

3.7.1.6 HEAT PUMP LOCKOUT

This menu item is available only in Heat Pump Mode with an operational outdoor temperature sensor. Enabling this option allows the thermostat to disable a heat pump and request AUX Heat below the Heat Pump Lockout Temperature.

3.7.1.7 HEAT PUMP LOCKOUT TEMPERATURE

This menu item is available only in Heat Pump Mode with an operational outdoor temperature sensor. With it you may set the outdoor temperature at which the thermostat will cease to call for heat pump sourced heat, and use the alternate AUX Heat source.

3.7.1.8 DEADBAND

When using auto-changeover, deadband provides a disal- lowed temperature range between the maximum heat temperature set point and minimum cool temperature set point. Deadband may be set from 3 to 5 degrees. With auto-changeover active and the Deadband set to 3°F and heat set to 70°F the minimum allowed cool temperature set point will be 73°F. If the cool temperature set point is lowered, then the heat temperature set point will be low- ered by the same amount maintaining the 3°F Deadband.

3.7.1.9 SWING 1

Swing 1 sets the temperature variation the system allows above the temperature set point before switching the first stage heat source off, or below the temperature set point before switching the first stage heat source on. In Cool, Swing 1 sets the temperature variation the system allows above the temperature set point before switching first stage of cooling on, or below the temperature set point before switching the first stage of cooling off.
