1.
Set all of the zone thermostats to the cooling mode.
2.
Reduce the cooling set point to 1° below the actual
zone temperature on all thermostats.
3.
First stage cooling should energize after a delay.
4.
Be sure the compressor and blower are activated.
Check that the zone, cool, and fan LEDs are on.
5.
Decrease the cooling set point more to achieve a second
stage call and check to see that the fan speed increases
and second stage cooling is energized. In variable speed
applications, when operating in low compressor speeds,
ensure that there is adequate air flow from each register
so as to get sufficient throw into the conditioned space.
If there is not sufficient airflow, try increasing the selected
blower speed.
6.
Adjust the thermostats until the temperature displayed is
5° higher than the actual temperature on all thermostats.
7.
The call for cooling should be canceled after a delay.
8.
Set all of the zone thermostats to the heating mode.
9.
Increase the heating set point to 1° above the actual
zone temperature on all thermostats.
10. After a delay, the unit should start up in the first stage
heating mode (H1).
11. Increase the heating set points more to achieve a
second stage call and check to see that the fan speed
increases and second stage heating is energized (H2).
12. Increase the heating set point to 4° above the
actual zone temperatures. Be sure the auxiliary
heat is energized and the fan speed increases when
applicable.
13. Set system to maintain desired comfort level.
14. Instruct the owner/operator of correct thermostat and
system operation.
NOTE: Unit check out can be accomplished by going to the
Test Mode screen at the MasterStat and selecting Central
Zone. The system will be controlled only by the MasterStat.
Any time superheat and subcooling is being checked, the
zone system must be in the central zone mode.
