Replace any wire that shows sign of aging and feels brittle to the touch.

POWER CONNECTION ///

USING 24V AC FROM THE HVAC UNIT

If you can get easy access to the HVAC unit’s transformer you may use this to power the base unit.

However please check the following before doing so:

1. That the transformer rating is not exceeded when you add the display load (approx 200mA).

2. That the transformer is not switched via other circuits and has a permanent primary feed from the power line.

3. That the voltage does not exceed 27V AC.

NOTE: If in doubt please use the power adapter supplied with the Thermostat Kit. To do this, simply route the power wire through the lower left grommet into the housing and plug in the power jack.

CONNECTION TO HVAC UNIT ///

CONNECTING TO THE GATEWAY ///

DISCOVERING NEW DEVICES

In order for the Gateway to control devices such as cameras, thermostats and switches, each device must be registered with the Gateway. The Gateway establishes a “secure wireless network” between itself and all discovered devices. The Gateway can only control devices that it has discovered.

New devices can be discovered at any time.

In order for the Gateway and its associated devices to be used, it must be configured first and the devices it controls must be discovered. All configuration and discovery is performed through the Gateway local administration pages. To get to these pages you must log on to the Gateway using your browser. Please refer to your User Manual for Gateway configuration information.

Once configured, a setup wizard will be presented.

SETUP WIZARD - DEVICE DISCOVERY START PAGE

When you get to Step #4 of the setup wizard, press the discovery button on the devices you wish to discover at this time. Click the ‘NEXT’ button when you have completed discovering your devices.

NOTE: This page will automatically refresh every 15 seconds to display newly discovered devices.

It will also automatically stop discovering devices after 15 minutes. You will be able to discover devices at a later time if you choose to do so.

OPERATIONAL MODES ///

OFF

The Heating and Cooling systems are both off and do not respond to any changes in temperature settings.

HEAT

The Heating system activates to maintain desired heating setting. The Heating system will be turned on at one degree Fahrenheit (approximately 5ºC) below the set point and will turn off at the set point.

COOL

The Cooling system activates to maintain desired cooling setting. The Cooling system will be turned on at one degree Fahrenheit (approximately 5ºC) above the set point and will turn off at the set point.

AUTO

The Thermostat will automatically switch between heat and cool modes to maintain the desired heating and cooling temperature settings. To ensure that the heating and air conditioning systems are not activated simultaneously, the system has a built-in offset. This offset maintains a minimum of three degrees Fahrenheit or Celsius between the desired heat and cool temperatures. If you try to change one temperature set point within three degrees of the other temperature set point, the

Thermostat will automatically adjust the other set point to ensure the offset is maintained.

For example, if you have the heat set to a desired temperature of 69ºF and you attempt to set the desired cooling temperature to 71ºF, the desired heating temperature will automatically decrease to

68ºF to maintain the 3ºF difference.

The AUTO mode automatically turns the Heating or AC on, based on the temperature ranges you entered for Cool and Heat. However, the first time the Thermostat changes the operating mode from heat to cool or from cool to heat, the temperature must rise two degrees above the set point for the change to occur. This keeps your HVAC system from overshooting and constantly alternating between the heater and air conditioner.
