WIRELESS HOME - BASICWalker Technologies’ “WIRELESS HOME - BASIC” is the lowest cost solution to control of baseboard heaters in a home or remote location. Each unit can control a single baseboard heater zone. Any other line voltage load can also be controllerd including lights, hot tubs and hot water tanks. Where a load that is larger than the maximum rated load is controlled an additional load control relay is required.

CONTROLLERS

WZ_LVS250 Single Zone Baseboard Controller The single zone LVS250 controls one zone of baseboard heating accurately to within a few tenths of a deg.C. The Walker Temperature Predictor in the software compensates for self heating and wall effects to ensure stable control. The LVS-250 responds to a knob setpoint or a supervisory command sent over the wireless network. The integral motion detector can turn down the heat based on occupancy to save energy.

LVS_250

WZ_TERMINAL_1 Multiple Zone Wireless Master Control BoxFor multiple zone baseboard control, the control-lers are linked by a wireless network “master” controller that determines system operation. The WZ_Terminal_1 allows operator input or a contact closure to trigger the “on” state of the controllers in the attached wireless system. When the switch is “on” the WZ_Terminal_1 transmits an “on” com-mand to all the controllers in the network. When the LVSTAT250 controllers are “on”, they control to the setpoint knob and when “off” control to the preset low temperature.

The WZ_Terminal_1 has the following inputs.

1. Trigger Input (contact closure)

2. Outdoor Temperature input

3. Terminal (RS232) input

WIRELESS HOME - BASICThe “WIRELESS HOME - BASIC” system can be configured to control multiple zones with various different strategies and options. Some of the features are listed below.

OPERATION

Occupied/Unoccupied StateCan be set by serveral means.

1. Pushing a remote switch.

2. Pushing a button on the WZ_TERMINAL_1

3. Contact closure from a remote switch or home control system.

4. Command fron local or dial up terminal interface.

Last TX MinutesIs the time since last transmission for each of the zones.

Unoccupied SetpointThe Unoccupied temperature setpoint can be fixed or based on outdoor temperature, so that as it gets colder outside the unoccupied temperature setpoint is adjusted higher to give insurance against power outages.

Minimm and Maximum SetpointThe minimum and maximum setpoints can be set for each zone. These override the knob setpoint.This is useful for keeping renters from turning up the heat to high or maintaining a minimum setpont.

Time ScheduleSet day and night time schedules during occupied mode. If you are away during the day, or not using some areas, there is no point heating empty spaces.

Night Setpoint If you normally open your window at night, having a night setpoint in a zone ensures your heat will turn down at night.. By adjusting the schedule “on: time, you can make sure it is warn when you get up.

No_Motion HoursIs the number of hours since motion was detected in the zone.

Connection Options

Local ConnectionBy using RS232 or a USB to RS232 convertor, a direct cable connection to the WZ_Terminal_I is possible. A standard terminal program such as Tera Term Pro will provide the connection.

Internet ConnectionBy ordering the WZ_TERMINAL_1 with an internet bridge installed (WZ_TERMINAL_1BR), a connection is available, via the internet, from any PC or handheld device that can support a serial interface. Most device app stores have VT100 terminal emulators available, (pie-VT100 for IPOD) but any terminal emulator will work. Dial-up via telephone modems is also supported.

WIRELESS HOME - BASICTo configure and control the “WIRELESS HOME BASIC” system, an RS232 terminal connection is used to connect to the WZ_TERMINAL_1. This gives access to the operation and setup screen. From this screen, the operator can command the on/off state of the heating system as well as set up particulars of its operation. This connection also allows you to remotely view operation or turn up the heat from your PC or phone.

Up to 20 zones of wireless WZ_LVS250 or other wireless devices
