DAMPER OPERATION
Problem - No airflow to the sleeping area AND living
area registers
Turn system off immediately. Both dampers may be wired
backwards at the subbase or at the damper actuator (closing
rather than opening).
Problem - No airflow to the sleeping area OR living
area registers
Turn system off. One of the dampers may be wired backwards
at the subbase or at the damper actuator (closing rather
than opening).
Problem - When directing airflow to the sleeping area, the
airflow is actually directed to the living area, and when
directing the airflow to the living area, the airflow is actually
directed to the sleeping area.
Turn system off. Check if the dampers are switched (sleeping
area damper is wired to the living area terminals and the
living area damper is wired to the sleeping area terminals.)
SENSOR INSTALLATION
Problem - nS message on thermostat.
Check that the sensor is wired correctly. Check for a short in
the sensor wiring.
Problem - Sleeping area temperature reading very high or
very low.
Check that the correct sensor(s) have been used. One TS51
sensor is used in a single sensor installation. Two TS52
sensors are used in a dual sensor installation.
COMFORT CONCERNS
Problem - Downstairs bedroom is too cold or too hot at night.
The Nighttime Airflow Control option directs more airflow to the
sleeping area and less airflow to the unoccupied living area. If
the downstairs bedroom is on the same HVAC trunk as the
living area, the downstairs bedroom may become uncomfortable
at night. Turn off the Nighttime Airflow Control option using the
User Options.
Problem - The room temperature on the thermostat seems
too high or too low.
The thermostat is factory calibrated within 1 degree.
However, if a homeowner finds the temperature “feels”
too high or too low, the thermostat can be calibrated to
what the homeowner feels is the correct temperature using
Installer option 13 for the living area and option 14 for
the sleeping area.
