ADDRESS THE THERMOSTATS AND SET HIGHEST ADDRESS

IMPORTANT!

THESE STEPS MUST BE DONE AT EACH THERMOSTAT

FOR COMMUNICATION TO WORK PROPERLY.

1.Press the Mode and Enter buttons simultaneously through the thermostat. It may take a couple of tries to get them pressed together.

This will enter the Thermostat Set Up Menu. The first menu item that will appear on the message center display is an informational item that indicates that only the Scroll Up, Scroll Down (two buttons located immediately

to the right of the message center display) and the

Enter buttons are used in thermostat set up. This will remain on the display for approximately 5 seconds or until any of the three aforementioned buttons is pressed. Thermostat Set Up is a series of sub-menus available to customize the thermostat in various ways. The thermostat Owners Manual and Installation Manual outline the thermostat set up features. The following steps will guide only through the Communications Set Up sub-menu (see ILLUSTRATION 5).

ILLUSTRATION 5 – Setting the Thermostat Address

2.Press the Scroll Down button until the “Communications Set Up” menu shows on the display.

3.Press the Enter button to select this sub-menu.

4.The first sub-menu item is “Set Thermostat ADDRESS”. Press the Enter button to select this item.

5.Set the address between 1 and 64 using the Scroll Up and Scroll Down buttons. (If using Model 8840 thermostats, see Appendix 1.)

Each thermostat must have a unique address

(i.e. no two thermostats can have the same address)

Start with address 1 and increment by 1 for each new address – do not skip an address. This will help to speed communications.

Write down the address for each thermostat on the Network Interconnection Worksheet (see ILLUSTRATION 3).

6.After the address has been selected, press the Enter button to store the address.

7.Use the Scroll Up and Scroll Down buttons to set the “Number of Stats On Network” to the highest address that will be on the thermostat network. This will be equal to the total number of thermostats on the network, unless one or more addresses are skipped.

IMPORTANT!

THIS NUMBER MUST BE SET THE SAME

AT EACH THERMOSTAT

8.After setting the number of thermostats on the network press Enter. The next item will be to “Set BAUD Rate”. The thermostat defaults to 9600 baud (bits per second).

If you want to change to 19200 baud operation, continue with #9.

If you want to operate at 9600 baud, press the Scroll Down button to get to the “EXIT” screen for the Communications Set Up sub-menu and go to #10.

9.Press Enter to set the baud rate. Use the Scroll Up or Scroll Down button to toggle between 9600 baud and 19200 baud. Press Enter when the baud rate desired is showing.

10.Press Enter to “EXIT” the Communications Set Up sub-menu. This will return you to the main menu.

11.Press the Scroll Down button until “EXIT” is displayed. Press the Enter button. The thermostat will then reset and return to normal operation.
