The thermostat can operate with other thermostats on a
tN4 network in a cool group. When operating as a cool
group, the air temperature readings of all the thermostats
in the group are averaged. A single thermostat controls the
operation of the cooling equipment and is called the cool
group master. This operation is based on the averaged
temperature of all the thermostats in the cool group.
In a cool group, one thermostat is assigned as the cool
group master. The cool group master operates the cooling
equipment for the group. The other thermostats are assigned
as members of the cool group. Cool groups are assigned
using a number 1 through 16 and there can be up to a
maximum of 16 cool groups on the entire tN4 network.
Each Cool Group can have up to 24 members.
• • To assign a thermostat as the cool group master of
group 1, go to the Adjust menu. Select Cool Master and
set to 01.
• • To assign a thermostat as a cool group member of group
1, go to the Adjust menu. Select Cool Member item and
set to 01.
• • Repeat the same steps to set up additional cooling
groups.
Time Clock Section H
The thermostat has a built-in time clock to allow the thermostat
to operate on a schedule. A battery less backup allows the
thermostat to keep time for up to 4 hours without power. • Use the Time menu to set the correct time.
